Metabool syndroom door light frisdrank

Het drinken van de 'light' versie van frisdranken vergroot je kansen op het metabool syndroom. Light frisdranken zijn wat dat betreft slechter voor je dan het eten van gefrituurd voedsel.

Minder overgewicht bij kinderen die borstvoeding kregen

Weer een reden om borstvoeding te geven is deze nieuwe studie waarin een relatie zichtbaar is tussen het krijgen van borstvoeding en een lager gewicht tijdens de kinderjaren. Of de moeder diabetes had of hoger gewicht speelde geen rol.

Slaaptekort kan tot overgewicht leiden

Afgelopen week dook het bericht op dat de Engelse onderzoeker Dr Shahrad Taheri een relatie legt tussen slaaptekort bij kinderen en overgewicht. Ik ben eens gaan spitten en stuitte op de ondergaande studie van deze onderzoeker die hij al eind 2004 publiceerde. Wat is nu precies het probleem ? Deelnemers aan de studie die te weinig sliepen hadden een verlaagd leptine niveau en een verhoogd ghrelin niveau. Deze hormonen spelen weer een rol bij overgewicht omdat deze combinatie de eetlust aanjagen.

Voor mij heel logisch want als je geen energie uit je slaap kunt halen dan zal je lichaam het uit voeding willen halen.

Rol van het Ghreline hormoon

Grote kans dat je maag veel van het hormoon Ghreline aanmaakt dat een signaal naar je hersenen stuurt. Zodra de maag gevuld is neemt de aanmaak van dit hormoon af en stopt het hongergevoel. Daarnaast reageren je darmen op calorierijk voedsel, zodra de darm zich vult worden er bepaalde eiwitten aangemaakt zoals de stof PYY die juist de trek vermindert. Het is dus een samenspel van hormonen en eiwitten die je hongergevoel aansturen. Gaat daar wat mis dan is het ook logisch dat de ene persoon een sterker hongergevoel heeft dan de andere.

Rol van het leptine hormoon

Leptine en insuline beïnvloeden de eetlust via de hypothalamus voornamelijk op de langere termijn. De leptine concentratie stijgt niet of nauwelijks in aansluiting aan een maaltijd, maar met name wanneer de vetmassa toeneemt en er chronische een grote fl ux van glucose en vetzuren in de adipocyt bestaat. Insuline stijgt uiteraard wel snel na een maaltijd, maar heeft veel tijd nodig om de hypothalamus te bereiken via de bloed-hersenbarrière. Pas wanneer de insuline concentratie in plasma chronisch is verhoogd, worden
hypothalame neurale circuits zodanig beïnvloedt dat de gevoeligheid van de hersenstam voor verzadigingssignalen toeneemt.

One study indicated that insufficient sleep at the age of 30 months was associated with obesity at the age of seven, suggesting that this could programme the part of the brain regulating appetite and energy expenditure", Dr Taheri explained.

Diet Soda Drinkers Gain Weight

People who drink diet soft drinks don't lose weight. In fact, they gain weight, a new study shows. The findings come from eight years of data collected by Sharon P. Fowler, MPH, and colleagues at the University of Texas Health Science Center, San Antonio. Fowler reported the data at this week's annual meeting of the American Diabetes Association in San Diego.

Why Almost Everything You've Been Told About Weight Loss is Wrong! With the release of The Fat Loss Bible, Anthony Colpo turns the world of weight loss on its head. After reading this myth-busting new book, you will realize that almost everything you have been told about weight loss is false.

Destroying the Myths

In the first section of the book, Colpo mercilessly takes aim at today's most pervasive weight loss myths, then blows each one to pieces with an unrelenting barrage of scientific data.

The biggest myth of all, states Colpo, is that calories are of little importance when attempting to lose weight. The Australian researcher lambasts those who claim the key to losing weight is lowering one's fat or carbohydrate intake. He is especially scornful of famous low-carbohydrate authors who enthusiastically promote the belief that, at identical caloric intakes, one can gain weight on a high-carbohydrate diet but lose weight on a low-carbohydrate diet. The late Dr. Atkins called this the "metabolic advantage", a term his followers still use today as if its existence had already been established beyond a doubt.

Those who promote the "metabolic advantage" theory are fond of selectively citing clinical trials with free-living subjects that have shown greater weight loss on low-carbohydrate diets. As The Fat Loss Bible explains, these authors rarely mention the even greater number of free-living studies that do not show greater weight loss on low-carb diets, and they almost never mention the numerous metabolic ward studies that have looked at this very issue.

Metabolic ward studies are the most important form of evidence, as they are the only clinical trials that ensure identical caloric intake among the subjects eating high- and low-carbohydrate diets. After all, if one is testing the belief that isocaloric diets of differing macronutrient composition can have differing weight loss effects, one must be sure that the diets consumed by the subjects are indeed isocaloric. Free-living studies fail dismally to meet this requirement; as The Fat Loss Bible explains, an abundance of evidence exists to show that dietary misreporting is the norm, not the exception, in free-living dietary trials.

In a world first, The Fat Loss Bible presents the results of each and every one of the metabolic ward dietary comparison studies conducted over the last five decades, and the results are unmistakable. When dietary misreporting is removed as a potential confounder, there is simply no evidence for a "metabolic advantage".

The fundamental requirement for weight loss is a calorie deficit. One must eat less calories than what they are expending, otherwise they simply will not lose weight. This is the reality, regardless of what eating style one chooses, be it low-carb, high-carb, or anywhere in between. By distracting people from this fundamental requirement, the promoters of the "metabolic advantage" theory inevitably set up many dieters for failure.

The reason some free-living clinical trials have shown greater weight loss on low-carbohydrate diets is because these regimens can have powerful satiating effects. Increased dietary protein, dietary fat, and low carbohydrate intakes all act through different mechanisms to decrease hunger. In other words, these diets make it easier for many people to lower their calorie intake. Because those following low-fat and calorie-restricted diets are most likely to underreport, the free-living studies give the false impression that lower-carb diets cause greater weight loss at a given calorie intake than higher-carb diets.

As the discrepancy between supportive and non-supportive free-living studies shows, the satiating effect of low-carb diets is not evident in all dieters. If those who do not experience such satiation are unaware that a calorie deficit, not reduction of carbohydrates, is the driving factor, then their efforts at weight loss will likely result in failure and frustration.

Colpo uses the same sort of meticulous science to destroy numerous other dietary myths, which are accepted as gospel by many in the health and nutrition arena. These myths include:

" Ketosis accelerates weight loss;

" Eating small, frequent meals helps you lose weight faster;

" Eating big meals at night makes you fat;

" Eating carbohydrates early in the day gives you energy, eating them at night makes you fat;

" Building muscle turns you into a "fat-burning dynamo".

The Fat Loss Bible presents study after study to show these and other beliefs are grounded, not in fact, but fantasy.

How to Really Lose Weight

Colpo is no armchair expert. In addition to his work as an independent researcher and author, Colpo is a certified fitness trainer who has worked with a wide variety of clients over the last over 16 years. In the second section of the book, Colpo presents the science-based principles he has developed for helping people lose weight.

Having established that a calorie deficit is essential for weight loss, Colpo explains the correct way to establish such a deficit. He warns against sudden, drastic, and excessive cuts in calorie intake, as these can induce ravenous hunger, mood disturbances, and rapid loss of precious muscle tissue.

Instead of resorting to the usual random and ineffectual method of cutting calories, The Fat Loss Bible describes in a step-by-step fashion how to calculate your own ideal daily calorie target. This is done by taking into account such factors as your current weight status and physical activity levels.

Having calculated your daily calorie target, The Fat Loss Bible then explains just how much protein, fat, and carbohydrate you should eat. The book also lists the type of foods that should form the foundation of your diet - fresh nutrient-dense Paleolithic-style foods such as meats, eggs, nuts, vegetables, and small amounts of fruit.

The Fat Loss Bible thoroughly addresses another subject commonly ignored by most weight loss books: Exercise. Colpo explains just why exercise is so important. Not only does it help establish a calorie deficit, but the right kind of exercise helps prevent muscle loss. Many people who lose weight end up smaller but still have a flabby look to their physiques. This is due to the fact that they have lost excessive amounts of muscle along with fat. If your goal is to have a lean attractive physique with good muscular tone, then muscle loss is to be avoided at all costs. Any weight you lose should be comprised primarily of fat.

Not any old form of exercise will suffice. Contrary to popular wisdom, endless hours of jogging or aerobics are not the best way to lose fat. The Fat Loss Bible describes the many benefits of weight training and brief-duration cardio and explains how you can institute an intelligently structured exercise routine.

Conclusion

The Fat Loss Bible is two-books-in-one; it debunks common weight loss myths, and then outlines a step-by-step method for losing weight based on solid science. It will completely change your thinking on weight loss.

Lucoxanthin (Bruin zeewier) zorgt voor 5-10% gewichtsverlies bij proefdieren

Japanse onderzoekers hebben ontdekt dat bruin zeewier (zit bijv in Miso soep) een stof lucoxanthin bevat die bij proefdieren tot een gewichtsverlies van 5-10% leidde. De onderzoekers denken dat er binnen 3-5 jaar een natuurlijke extract of medicijn kan worden ontwikkeld dat kan helpen overgewicht te bestrijden. Verder stimuleert de stof de aanmaak van het Omega 3 vetzuur DHA door de lever, verhoogde niveau's van dit vetzuur verlagen het slechte cholesterol dus gunstig voor je hart en bloedvaten. Het voordeel tov visolie suppletie is dat deze stof geen vieze smaak heeft. De onderzoeker waarschuwt wel dat het eten van veel bruin zeewier weinig effect heeft omdat de stof moeilijk geabsorbeerd wordt. Dus moeten we dus nog een paar jaar wachten....

Brown seaweed contains promising fat fighter, weight reducer

Chemists in Japan have found that brown seaweed, a flavor component used in many Asian soups and salads, contains a compound that appears in animal studies to promote weight loss by reducing the accumulation of fat. Called fucoxanthin, the compound achieved a 5 percent to 10 percent weight reduction in test animals and could be developed into a natural extract or drug to help fight obesity, the researchers say.

The compound targets abdominal fat, in particular, and may help reduce oversized guts, the scientists say. Their study was presented today at the 232nd national meeting of
the American Chemical Society.

Fucoxanthin is a brownish pigment that gives brown seaweed its characteristic color and also conducts photosynthesis (the conversion of light to energy). It is found at high
levels in several different types of brown seaweed, including a type of kelp that is used in traditional Japanese miso soup. But fucoxanthin is not found in abundance in green
and red seaweed, which also are used in many Asian foods, the researchers say.

The brown seaweed used in the current study was Undaria pinnatifida, a type of kelp also known as wakame, which is widely consumed in Japan. As kelp forests are found
in abundance along the California coast, the new research findings could represent a potentially lucrative market if kelp -- of which there are many varieties -- can be
developed into effective anti-obesity drugs, according to the scientists.

"I hope that our study [points to a way to] help reduce obesity in the U.S. and elsewhere," says study leader Kazuo Miyashita, Ph.D., a chemistry professor at Hokkaido
University in Hokkaido, Japan. The compound appears to fight fat through two different mechanisms, he says.

The study involved more than 200 rats and mice. In obese animals fed fucoxanthin, the compound appeared to stimulate a protein, UCP1, that causes fat oxidation and
conversion of energy to heat, Miyashita says. The protein is found in white adipose tissue, the type of fat that surrounds internal organs. As the abdominal area contains abundant adipose tissue, the compound might be particularly effective at shrinking oversized guts, the researcher says. This is the first time that a natural food component has been shown to reduce fat by targeting the UCP1 protein, he says.

The pigment also appeared in animal studies to stimulate the liver to produce a compound called DHA, a type of omega-3 fatty acid, at levels comparable to fish oil supplementation. Increased levels of DHA reduce 'bad cholesterol' (low density lipoprotein), which is known to contribute to obesity and heart disease. But unlike fish oil supplements, fucoxanthin doesn't have an unpleasant smell, Miyashita says. No adverse side effects from fucoxanthin were reported in the mice and rats used in the study.

But eating lots of seaweed is not the quickest or most convenient path to weight loss, Miyashita cautions. He notes that a person would probably need to eat huge amounts of brown seaweed daily to cause noticeable weight loss. That's because fucoxanthin is tightly bound to proteins in the seaweed and is not easily absorbed in the form of whole seaweed. However, he hopes to extract the most active form of fucoxanthin from brown seaweed so that it can be developed into a pill that people can take daily or as needed.

Human studies are planned, the researcher says, but adds that it may take three to five years before such an anti-obesity pill is available to consumers. Until then, people should continue to eat a well-balanced diet and get plenty of exercise, he says. Funding for the current study was provided by the Japanese government.

Vetarm niet de oplossing voor zwaarlijvigheid

Walter Willett: "Vetarme diëten zijn niet de oplossing voor de epidemie van zwaarlijvigheid"

Professor Walter Willett, President van de afdeling Voeding van de ''School van de Volksgezondheid van Harvard (Boston, Massachusetts)'', wordt gezien als een van de betere, zoniet de beste voedingsdeskundige ter wereld. Aan zijn zijde werkt het meest prestigieuze team van epimideologen aan dit probleem.

In het onderhoud met Thierry SOUCCAR verklaart President Willett de meest recente gegevens omtrent de factor voeding gelieerd aan diabetes en zwaarlijvigheid. De meest recente gegevens zijn gepubliceerd in de belangrijkste medische tijdschriften. Professor Willett heeft zijn medewerking gegeven aan het boek ''Sante, mensonges et propagande'' van Thierry SOUCCAR en Isabelle ROBARD. (zie fonteine.com Nieuws September 2006)

Welke raad kan men geven om in goede gezondheid te blijven ?

Het is belangrijk dun en actief te blijven; regelmatig een sport, zoals wandelen, te beoefenen. Zoveel als mogelijk verzadigde vetten en transvetten vervangen door meervoudig onverzadigde vetten; deze bevinden zich in oliën. Weinig geraffineerde glucides gebruiken, die rijk aan vezels zijn. Aardappelen met mate ; dit product is niet geschikt voor ''het zittende leven''. Rood en wit vlees afwisselen. Rood vlees is niet goed als het dagelijks gebruikt wordt. Vis lijkt een beschermer.De eenvoudige suikers met mate gebruiken: dit om verhoging van de suikerspiegel zoveel mogelijk te voorkomen.

Korte, vertaalde samenvatting door Ditta van Herk

Zetmeel en tarwe = dikmakers

Het eten van te veel deegwaren en zetmeelhoudende producten kan er ook aan bijdragen dat men aankomt. Ramadan is vaak een tijd waarin vrouwen hun kookkunsten willen tonen. Het bakken van brood wordt vaak gezien als visitekaartje van de gastvrouw; wie een goed brood kan bakken, die kan pas echt koken! Maar niet iedereen ziet brood als het hoogtepunt van goede kookkunsten. Verscheidene boeken van diëtisten leggen heel precies uit hoe zetmeel en granen bijdragen aan gewichtstoename. De meeste granen en peulvruchten, in combinatie met melk en vlees, dragen bij aan de zure omgeving in ons lichaam, wat een nadelig effect heeft op de gezondheid

De beste manier om het probleem van het eten van te veel zetmeel op te lossen, is er zeker van te zijn dat je de juiste porties van de verschillende voedselsoorten binnenkrijgt, wat nodig is om af te kunnen vallen. Stel je voor dat je je bord samenstelt uit enkel en alleen groenten en dat je slechts melk, vlees en granen mag gebruiken als smaakmakers/garnering. Beperk jezelf tot één kopje graan (rijst/tarwe/bulgur) per dag. Ga selderij zien als iets waar je smeerkaas of pindakaas op kunt smeren, in plaats van op brood. Dip worteltjes in de hoemoes, in plaats van brood. Vul koolbladeren, in plaats van tortilla’s. Stop niet met het eten van brood en vlees, maar laat ze meer op de achtergrond of bewaar ze voor bijzondere gelegenheden. Je zou moeten streven naar 70 % groenten (en fruit, maar hier iets minder van) en 30% aan granen, bonen en melkproducten en vlees

Er is nog een hele voedselcategorie die bijdraagt aan gewichtsverlies, omdat de producten bitter zijn, of omdat ze een hoog watergehalte hebben. Het is bekend dat ieder voedsel of kruid dat bitter is meehelpt vetten sneller en efficiënter door het systeem te loodsen. Ook hier geldt dat je matig moet zijn in het nuttigen ervan en de juiste porties tot je moet nemen. Het is geen voedsel dat je onbeperkt kunt eten. Bitter en voedsel met een hoog watergehalte zijn onder andere: haver, maïs, rogge, adzuki-bonen, komkommer, aubergine, zoete aardappelen, selderij, asperges, spruitjes, kool en andere spruitachtigen. Je kunt ook kruiden gebruiken die de spijsvertering stimuleren. Dit zijn onder andere: kardemom, gember, kaneel, cayennepeper

Grapefruits hongeren vetcellen uit

Zonder dat je op dieet bent kun je afvallen als je grapefruits of grapefruitsap aan je menu toevoegt. Dat zeggen onderzoekers van de Amerikaanse Scripps Clinic, die proeven deden met honderd mannen en vrouwen van gemiddeld 98 kilo.

Algemene tips

Vegetarisch eten biedt op zich geen garantie voor gewichtsverlies. Er zijn vegetariërs die zich volstoppen met vette en gesuikerde voeding, met name geraffineerde koolhydraten, en die te weinig fruit en groenten eten. Daarom volgen hier een aantal richtlijnen die je kunnen helpen om een geschikt dieet samen te stellen:

• Denk eraan: onthouding en honger zijn geen voorwaarden om af te slanken. Integendeel: ze werken enkel frustrerend en kunnen leiden tot vreetbuien.

• Blijf niet dooreten tot je een volledig “vol gevoel” hebt. Het duurt zo’n 20 minuten tot de hersenen het signaal krijgen dat het lichaam voldoende voedsel tot zich heeft genomen en dus verzadigd is.

• Denk eraan je voedsel goed te kauwen. Het kauwen helpt het lichaam bij het efficiënter benutten van voedingsstoffen. Daardoor wordt voorkomen dat sommige slecht verteerde voedingsmiddelen worden opgeslagen onder de vorm van vet in de weefsels. Goed kauwen is meer dan ervoor zorgen dat je het voedsel kan inslikken. Het zorgt ervoor dat je je veel vlugger verzadigd voelt met minder grote hoeveelheden voedsel. Je kan hierbij denken aan een oud gezegde: “kauw je drinken en drink je eten.”

• Donkergroene groenten: laat niet na om zo lang als ze voorradig zijn ze royaal toe te voegen aan je dagelijkse menu. Je kan ze sappig maken met water of sinaasappels; voeg citroen toe en kruiden zoals munt of citroenmelisse. Ook bij mensen met een genetische aanleg voor zwaarlijvigheid wordt het al dan niet opslaan van extra kilo’s sterk bepaald door een verantwoorde voedselkeuze en de mate van lichaamsbeweging.

• Rauwkosten: neem grote porties. Je kan heerlijke saladedressings maken met citroen, sinaasappelsap, stukjes groene appel, aardbeien of gedroogde vruchten, balsamico azijn, kruiden,…

• Voeg geregeld gebroken lijnzaad toe aan je maaltijden. Het bevat veel essentiële vetzuren die belangrijk zijn voor allerlei lichaamsfuncties. Bovendien helpt het om de zin in eten, die leidt tot overgewicht, te verminderen.

• Water: drink minstens anderhalve liter (mineraal)water per dag. Dit helpt bij de afvoer van toxische reststoffen die in de lichaamsweefsels opgeslagen zijn. Hierdoor kunnen zuurstof en voedingsstoffen de cellen gemakkelijker bereiken en verloopt de afvoer van opgeslagen vet efficiënter.

• Neem de hoofdmaaltijd ’s middags en een lichte maaltijd ’s avonds. Probeer niet meer te eten na zes uur ’s avonds. Het spijsverteringsstelsel werkt het best rond de middag. ’s Avonds vertraagt de werking ervan, dus als je te laat nog eet, wordt dit voedsel niet meer volledig verteerd en wordt het opgeslagen als vet.

Low-Fat Diet and Chronic Disease Prevention

The Women’s Health Initiative Randomized Controlled Dietary Modification Trial was designed to study a low-fat diet, a nutritional approach to prevention of chronic diseases that was considered promising. The negative findings from the trial were both unexpected and disappointing to nutrition authorities. The authors’ public responses to the findings articulated an unwillingness to believe the finding that a low-fat diet did not prevent breast or colon cancer or heart disease. The negative results should stimulate work on alternate hypotheses, and reconsideration of the long-standing proscription against dietary fat.

Clock gene plays role in weight gain, study finds

Scientists have discovered that a gene that participates in the regulation of the body's biological rhythms may also be a major control in regulating metabolism. Their finding shows that mice lacking the gene Nocturnin, which is regulated by the circadian clock in the organs and tissues of mammals, are resistant to weight gain when put on a high fat diet and also are resistant to the accumulation of fat in the liver.

UCLA Identifies New Molecule Involved in the Body’s Processesing of Dietary Fat

UCLA investigators have identified a new molecule that may help regulate the delivery of fats to cells for energy and storage.

Published in the April issue of the journal Cell Metabolism, the finding could lead to a better understanding of how we utilize fats from the foods we eat.

"We thought that we had figured out how the body digests and uses fats, but we have identified a completely new player in the game," said the study's author Anne Beigneux, assistant investigator at the David Geffen School of Medicine at UCLA.

Digested fats travel to the small intestine, where they are packaged into chylomicrons, which are large, spherical particles filled with triglycerides.

Chylomicrons then travel through the bloodstream and deliver triglycerides to the skeletal muscles and heart — tissues that are hungry for fuel — or to adipose tissue for energy storage. Molecules called proteoglycans, attached to the inside walls of capillaries, wait like baseball players with their mitts open, poised to catch the passing chylomicrons.

Proteoglycans hold the chylomicrons steady while the triglycerides are broken down or hydrolyzed by the enzyme lipoprotein lipase (LpL). The triglyceride breakdown products are then taken up and used by cells.

"Previously we didn't know what molecule in the capillaries facilitated the capture of chylomicrons and facilitated the interaction with lipoprotein lipase," said Dr. Stephen Young, study author and investigator at the David Geffen School of Medicine at UCLA. "We think that we've found the missing piece of the puzzle."

Investigators discovered that a protein called glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 (GPIHBP1) may be the missing link.

Scientists found that mice deficient in GPIHBP1 develop very high triglyceride levels, even on a normal diet, demonstrating that fats in the bloodstream are not readily metabolized in the absence of GPIHBP1.

Laboratory tests confirmed that GPIHBP1-deficient mice had much higher levels of chylomicrons in the bloodstream than normal mice. The GPIHBP1-deficient mice had grossly milky plasma, reflecting very large amounts of triglycerides in the blood.

"These findings indicate a defect in the breakdown of chylomicrons in mice that don't have GPIHBP1," Beigneux said.

Weight gain in pregnancy linked to overweight in kids

Pregnant women who gain excessive or even appropriate weight, according to current guidelines, are four times more likely than women who gain inadequate weight to have a baby who becomes overweight in early childhood. These findings are from a new study at the Department of Ambulatory Care and Prevention of Harvard Medical School and Harvard Pilgrim Health Care and are published in the April issue of the American Journal of Obstetrics and Gynecology.

A study by a UB pediatric researcher investigating the causes of weight gain in children after they have their tonsils and adenoids removed to treat sleep-disordered breathing has shown that removing these tissues results in less fidgeting and other non-exercise motor activity. This reduction in motor activity left an excess of calories, findings showed, resulting in an average 13 percent increase in excess weight based on a participant's age, sex and height.

New Joslin Study Reveals How a Specific Fat Type Can Protect Against Weight Gain and Diabetes

A new study from Joslin Diabetes Center may shed light on why some people can eat excessive amounts of food and not gain weight or develop type 2 diabetes, while others are more likely to develop obesity and this most common form of diabetes on any diet. The study, which used two strains of mice with differing tendencies to gain weight and develop diabetes on a high-fat diet, identified genetic and cellular mechanisms that may prevent certain mice on a calorie-dense diet from gaining weight and developing metabolic syndrome.

“Although this study was done with mice, it points out new mechanisms that may underlie the ability of genetically different mice -- and perhaps genetically different people -- to not gain much weight on high caloric diets,” said lead investigator C. Ronald Kahn, M.D., an internationally recognized researcher who is Head of Joslin’s Section on Obesity and Hormone Action and the Mary K. Iacocca Professor of Medicine at Harvard Medical School.

It has long been known that people significantly differ in their tendency to gain weight and develop metabolic syndrome, a group of conditions including hypertension, abdominal obesity, high triglycerides and glucose intolerance that can lead to type 2 diabetes. More than 60 million Americans either are obese or have metabolic syndrome, putting them at risk for type 2 diabetes and its frequent complications, including cardiovascular disease and other serious conditions. Currently 21 million Americans have diabetes and approximately one-third of them do not even know they have the disease. Formerly known as adult-onset diabetes, type 2 diabetes is occurring more frequently in young adults and even children.

The Government Makes You Fat

Michael Pollan: Michael Pollan looks at the way Government policy determines what we eat and why "the most reliable predictor of obesity inAmerica today is a person's wealth." He quotes a study by Drewnowski of the University of Washington, who determined that a dollar will buy 1200 caloriesof cookies or chips but only 250 calories of carrots. If you don't have a lot of money, the most rational thing to do is buy junk food to get the mostcalories for your buck. [Ben Licher]

Low Glycaemic Index Diet Improves Insulin Sensitivity in Overweight Women

Switching to a low glycaemic index (GI) diet from a high GI diet can result in improvements in insulin sensitivity, and may thereby lower the risk of type 2 diabetes in overweight or obese individuals with impaired glucose tolerance, according to a controlled, 24-week, crossover study presented here at the 15th European Congress on Obesity (ECO).

New Science-Based Guide To Natural Fat-Loss

American consumers have long been skeptical about weight-loss supplements, and rightly so. With dozens of nutrients, herbs, and food extracts being marketed as aids for weight loss, there is shockingly little reliable information available concerning the safety and efficacy of any given product. What is more, many so-called miracle pills and quick fixes fail to deliver on the grand weight-loss promises they make, others come with unpleasant side effects, and some have even proven to be dangerous when used incorrectly.

OHSU Researchers Show How Obesity Causes Breakdown In Brain-Based System Which Regulates Appetite and Body Weight

New research led by scientists at the Oregon National Primate Research Center demonstrates how obesity causes the breakdown of a brain system that regulates appetite. The research provides a clear picture of some factors involved in obesity. More than 60 percent of American adults are overweight and more than 30 percent are obese. The study results may have also identified possible targets for new drug therapies aimed at assisting individuals in weight loss. The research is published in the March issue of Cell Metabolism.

The research provides new understanding of leptin resistance. Leptin is a hormone secreted by fat cells. It can suppress food intake by affecting brain cells that control appetite. However, high levels of leptin which can be found in severely overweight individuals, can lead to leptin resistance. Leptin resistance means that the body no longer responds to the hormone's weight suppressing effects.

The research was conducted in mice and involved two separate groups that were fed high-fat and low-fat diets. Over time, the high-fat diet group developed symptoms of diabetes and obesity, as is often the case in humans. The low-fat diet group did not develop these health problems.

"This research demonstrates how a portion of the hypothalamus of the brain, called the arcuate nucleus, is negatively impacted by an overabundance of leptin," explained Michael Cowley, Ph.D., an associate scientist in the Division of Neuroscience at ONPRC. "By developing a special test of neuronal function, we were able to witness the breakdown in this group of specialized cells. Eventually the cells behaved as if there was no leptin present, even though levels were 40-times higher than in normal animals. We were also able to witness the eventual repair of this important system which occurs as the mice lost weight when returned to a low fat diet."

More specifically, the scientists determined that leptin resistance prevented the arcuate nucleus from taking part in an important signaling function that regulates appetite and body weight. Meanwhile, other portions of the weight regulation system remained intact and in fact became more responsive, thereby suggesting that arcuate nucleus function is the point of breakdown during leptin deficiency.

Research shows BMI often not an accurate indicator of body fat

Body mass index, or BMI, long considered the standard for measuring the amount of fat in a person’s body, may not be as accurate as originally thought, according to new research.

A research team from Michigan State University and Saginaw Valley State University measured the BMI of more than 400 college students – some of whom were athletes and some not – and found that in most cases the student’s BMI did not accurately reflect his or her percentage of body fat.

The research is published in the March issue of Medicine and Science in Sports and Exercise, the official journal of the American College of Sports Medicine.

BMI is determined by this equation: A person’s weight divided by his or her height squared. Generally a BMI of 25 or above indicates a person is overweight; 30 or above indicates obesity. A person with a higher BMI is thought to be at a greater risk of heart disease, diabetes and other weight-related problems.

“The overlying issue is the same criteria for BMI are used across the board,” said Joshua Ode, a Ph.D. student in the MSU Department of Kinesiology and an assistant professor of kinesiology at Saginaw Valley. “Whether you’re an athlete or a 75-year-old man, all the same cut points are used.”

“BMI should be used cautiously when classifying fatness, especially among college-age people,” said Jim Pivarnik, an MSU professor of kinesiology and epidemiology. “It really doesn’t do a good job of saying how fat a person really is.”

Obesity And Environmental Chemicals: Research Probes Potential Link

A team of researchers at UNH is investigating whether the increasing ubiquity of chemical flame retardants found in foam furniture, carpeting, microwaves and computers might be related to the climbing rate of obesity in the United States.

“Environmental chemicals are a possible third component to the obesity epidemic, along with diet and exercise,” says Gale Carey, professor of nutrition and a leader of the research project, along with professor of nutrition Anthony Tagliaferro and Deena Small, assistant professor of molecular biology and biochemistry. The trio received funding for the project from the President’s Excellence Initiative Awards, which provide support for interdisciplinary research.

The flame retardants, called polybrominated diphenyl ethers (PBDEs), have been produced since the 1960s; they’re now found in consumer products like carpeting, upholstered furniture, computers and hair dryers, where they retard the combustibility of these products. It’s estimated that American consumers come into contact with up to 100 products containing PBDEs per day.

Fetal Exposure to Common Chemicals Can Activate Obesity

Exposure to environmental chemicals found in everyday plastics and pesticides while in the womb may make a person more prone to obesity later in life, new research indicates. Obesity is generally discussed in terms of caloric intake - how much a person eats - and energy output - how much a person exercises. But now Frederick vom Saal, professor of biological sciences in University of Missouri-Columbia's College of Arts and Science, has found that when fetuses are exposed to these chemicals, the way their genes function may be altered to make them more prone to obesity and disease.

Belly fat may drive inflammatory processes associated with disease

As scientists learn more about the key role of inflammation in diabetes and heart disease, new research from Washington University School of Medicine in St. Louis suggests that fat in the belly may be an important promoter of that inflammation. The researchers have confirmed that fat cells inside the abdomen secrete molecules that increase inflammation. This is the first evidence of a potential mechanistic link between abdominal fat and systemic inflammation.

Paleo Diet Overview

This diet really comes from a collection of research and writings about the diet of human ancestors. Although these writings are not in total agreement as to what this diet was, there are many common themes. "Modern Paleolithic" diets are based on the idea that humans and their ancestors were evolving for millions of years before reaching the Neolithic period during which farming and other advancements radically changed the human diet, to the detriment of human health. Further changes in the last century, and even more in the last two decades, have accelerated this process. [Ben Licher]

Aging, Adiposity, and Calorie Restriction

Calorie restriction in adult men and women causes beneficial metabolic, hormonal, and functional changes, but the precise amount of calorie intake or body fat mass associated with optimalhealth and maximum longevity in humans is not known. In addition, it is possible that even moderate calorie restriction may be harmful in specific patient populations, such as lean persons who have minimalamounts of body fat.

Natural fibre may take extra pounds away

The fibre is called oligo fructose. “It’s not a chemical or a drug. In fact it’s a food product that is already being used in things like yogurt, cereal and baby food. We have found in a previous study with rats that the fibre increases the levels of a satiety hormone called glucagon-like peptide (GLP-1) in the body and increases a gene in the intestines that helps the body to create more GLP-1.” In a study with genetically obese rats, Reimer and U of C PhD Student Jill Parnell found that consuming the natural fibre helped the rats to significantly reduce their food intake and improved their blood lipid profile.

Cravings for chocolate increased by dieting

New research led by Professor Ben Fletcher and Dr Karen Pine at the University’s School of Psychology, has revealed that dieting leads women into a vicious cycle of negative emotions which in turn provokes cravings for the very foods they are trying to avoid, chocolate being one of the most powerful. "An ideal target food for such research is chocolate, since it is often the subject of a love-hate relationship," said Dr Pine. "While it is loved for its pleasurable taste, scent and texture, it is often disliked by some for its perceived high calorific and sugar content and, as a result, some people make a conscious effort to restrict their consumption of it."

Vagus Nerve Stimulation May Help Prevent Obesity

Scientists at the Medical University of South Carolina (MUSC) have determined that vagus nerve stimulation (VNS) may play a role in developing clinical treatments for obesity and emotional eating. The first of its kind, the study examined the effects of VNS on food cravings in adults with major depression.

"While it is still too early to think of cervical VNS as a treatment for emotional eating or obesity, the study results do demonstrate the need for more investigation and suggest that it is plausible that cervical VNS could one day be used to treat obesity," Borckardt said. "We also learned that VNS device settings may be key in understanding how to target specific areas in the brain responsible for satiety, and emotional eating."

Food cravings are related to eating behaviors and therefore they may influence weight change over time. This study provides initial evidence that food cravings, at least for sweet foods, may be one mechanism underlying the relationship between acute left cervical VNS and eating behaviors and weight. This type of VNS involves implanting the electrical device under the patient's skin in the upper left quadrant of the chest. "For some of the patients, we saw a decrease in the craving of sweets, whereas for others, we saw an increase," said Jeffrey Borckardt, Ph.D., MUSC Brain Stimulation Laboratory, Institute of Psychiatry, and one of the study's authors. "Based on certain VNS device parameters, {i.e. electrical current intensity, length of time the device was on or off, depression severity, body mass index, and emotional eating tendencies} we could predict if cravings would increase or decrease when the VNS device was turned on and off."

New Data On Fructose-sweetened Beverages And Hepatic Metabolism

According to figures published by the World Health Organitzation (WHO), in the year 2015 some 2.3 bn adults will be overweight and more than 700 million will suffer from obesity, a pathology which is increasingly being seen in children. In addition, for some time now the high incidence of obesity in developed countries has coincided with an increase in the consumption of beverages sweetened with fructose, a powerful sweetener. A team from the University of Barcelona (UB) has recently published a study in the journal Hepatology which provides clues to the molecular mechanism through which the fructose in beverages may alter lipid energy metabolism and cause fatty liver and metabolic syndrome.

The study was led by Dr Juan Carlos Laguna of the Department of Pharmacology and Therapeutic Chemistry at the Faculty of Pharmacy, who is also the director of the research group “Nuclear receptors regulating energy metabolism as pharmacological targets”, with the participation of Núria Roglans, Laia Vilà, Mireia Farré, Marta Alegret, Rosa Mª Sánchez and Manuel Vázquez-Carrera.

This preclinical study published in Hepatology was carried out with laboratory rats receiving fructose- or glucose-sweetened liquid intake. No solid food was given. “The fructose in fruit has nothing to do with this study,” stresses Professor Laguna. “Fruit is healthy and its consumption is strongly recommended. Our study focuses on liquid fructose intake as an addition to the ordinary diet.”

Fructose is mainly metabolized in the liver, the target organ of the metabolic alterations caused by the consumption of this sugar. In this study, rats receiving fructose-containing beverages presented a pathology similar to metabolic syndrome, which in the short term causes lipid accumulation (hypertriglyceridemia) and fatty liver, and at later stages hypertension, resistance to insulin, diabetes and obesity.

The fructose used to sweeten beverages alters the lipid metabolism in the liver and, according to the authors, represents a calorie overload to which the body’s metabolism is unable to adapt. Specifically, fructose increases fat synthesis in the liver and reduces its degradation through action on a specific nuclear receptor (PPARa), which controls fatty acid ß-oxidation. “The most novel finding,” says Laguna, “is that this molecular mechanism is related to an impairment in the leptin signal. Leptin is a hormone that plays a key role in the body’s energy control; among its peripheral actions, it accelerates fat oxidation in the liver and reduces its synthesis.”

How we can stop stress from making us obese

Professor Herbert Herzog, Director of the Neuroscience Research Program at the Garvan Institute of Medical Research, together with scientists from the US and Slovakia, have shown that neuropeptide Y (NPY), a molecule the body releases when stressed, can ‘unlock’ Y2 receptors in the body’s fat cells, stimulating the cells to grow in size and number. By blocking those receptors, it may be possible to prevent fat growth, or make fat cells die. “We have known for over a decade that there is a connection between chronic stress and obesity,” said Professor Herzog. “We also know that NPY plays a major role in other chronic stress-induced conditions, such as susceptibility to infection. Now we have identified the exact pathway, or chain of molecular events, that links chronic stress with obesity.” “There is not much we can do about the increased levels of NPY caused by stress, but we can do something about the damage it causes. If we can interfere before it causes fat to amass, it could have a major impact on cardiovascular disease, diabetes, and cancer (which all have links with obesity).”

Diet for the metabolic effect

You are what you eat, and you burn what you eat. These are two simple ways of expressing deeper biochemical truths that impact your weight loss efforts. The metabolism has different fuels at its disposal. However, it is not as discriminating as we would like in which ones it chooses to burn. Ironically, the body becomes efficient at burning what it is given. If you eat sugar, you will be a sugar burner. So how do you become a fat burner? You eat the way your ancestors ate; lean protein, high fiber, and that’s right, fat; the right kind.

Obesity Surgery Can Lead to Memory Loss, Other Problems

Weight loss surgery, such as gastric bypass surgery, can lead to a vitamin deficiency that can cause memory loss and confusion, inability to coordinate movement, and other problems, according to a study published in the March 13, 2007, issue of Neurology®, the scientific journal of the American Academy of Neurology. The syndrome, called Wernicke encephalopathy, affects the brain and nervous system when the body doesn’t get enough vitamin B1, or thiamine. It can also cause vision problems, such as rapid eye movements. The study found that the syndrome occurs most often in people who have frequent vomiting after the surgery. It usually occurs within one to three months after the surgery, although one case occurred 18 months after surgery.

Do low-fat foods make us fat?

Recent Cornell studies in movie theatres, holiday receptions, and homes showed people eat an average of 28% more total calories when they eat low-fat snacks than regular ones. "Obese people can eat up to 45% more," reports lead researcher Brian Wansink (Ph.D.), in the book, Mindless Eating: Why We Eat More Than We Think.

"People don’t realize that low-fat foods are not always low-calorie foods," says Wansink. Fat is often replaced with sugar. Low-fat snacks are an average of 11% lower in calories, but people wrongly believe they are around 40% lower.

In one study, two groups of people attending a holiday open-house were given identical regular chocolates that were labeled as either "Regular" or as "Low-fat." People served themselves an average of a third more of the candies, which would have translated into 28% more calories if they had actually been low-fat. A second study showed this is because "people believe they will feel less guilty eating the low-fat foods, so they tend to overindulge, says Pierre Chandon, co-author and marketing professor at INSEAD in France. Fat is often replaced with sugar.

When the package says 'low fat,' the calories can pile up, Cornell study of snack foods finds

People -- especially overweight people -- consume up to 50 percent more calories when they eat low-fat versions of snack foods than when they eat the regular versions, according to a new Cornell study.

Further, a companion study finds, when food labels show serving sizes on such packaged low-fat snacks as granola or chocolates, normal-weight people tend not to overeat them while overweight people do.

"This is a world of fat-free, carb-free and sugar-free products," said Brian Wansink, the John S. Dyson Professor of Marketing and of Applied Economics at Cornell. In fact, many low-fat-labeled foods have only about 30 percent fewer calories than their regular counterparts.

"Often, the fat-free version is not much lower calorie than the regular version," Wansink said. "Low-fat labels trick people into eating more than regular labels. But the cruel twist is that these labels have an even more dramatic impact on those who are overweight. They are at danger for really overindulging when they see something with a low-fat label. If we are looking for an excuse to eat, low-fat labels give it to us."

He recommends that low-fat-labeled foods post larger, more realistic serving sizes, which might deter people from eating too much by giving them a more accurate calorie count.

The study, conducted with Pierre Chandon, a marketing professor at INSEAD, an international business school in France, is published in the November issue of the Journal of Marketing Research and reported in Wansink's book, "Mindless Eating: Why We Eat More Than We Think."

What makes food fattening?

The theory described in this article assumes that the body-fat set point – how much body fat the brain tries to maintain – is controlled by flavor-calorie associations. Calorie-associated flavors raise the set point – the stronger the association, the greater the increase. In the absence of calorie-associated flavors, the set point declines. Given some plausible assumptions, themechanism regulates body fat according to the availability of food, increasing body fat when food is abundant, decreasing body fat when food is scarce. The theory explains a wide range of human and animal data, including effects and correlations involving pre-exposure, pureeing, moistening food, bland food, glycemic index, supermarket food, junk food, fasting, intragastric feeding, and income. It also helped find a new way to lose weight.

Eat Beans Weigh Less

A presentation at the recent Experimental Biology Conference revealed that people who include beans in their diets have healthier diets overall, lower body weights, and reduced risk of obesity. Researchers used data from the National Nutrition and Health Examination Survey (1999-2002) to study the associations between bean consumption, nutrient intake, and certain health parameters among children and adults. Children who ate beans not only had greater intakes of fiber (more than one-third higher), magnesium, and potassium, but showed a trend toward reduced risk of being overweight. Bean-consumers between the ages of 12 and 19 weighed 7 pounds less and had nearly an inch smaller waist circumference than their non-bean-consuming peers.

New Scientific Review Shows Vegetarian Diets Cause Major Weight Loss

A scientific review in April’s Nutrition Reviews shows that a vegetarian diet is highly effective for weight loss. Vegetarian populations tend to be slimmer than meat-eaters, and they experience lower rates of heart disease, diabetes, high blood pressure, and other life-threatening conditions linked to overweight and obesity. The new review, compiling data from 87 previous studies, shows the weight-loss effect does not depend on exercise or calorie-counting, and it occurs at a rate of approximately 1 pound per week.

The Effects of Grapefruit on Weight and Insulin Resistance: Relationship to the Metabolic Syndrome

Half of a fresh grapefruit eaten before meals was associated with significant weight loss. In metabolic syndrome patients the effect was also seen with grapefruit products. Insulin resistance was improved with fresh grapefruit. Although the mechanism of this weight loss is unknown it would appear reasonable to include grapefruit in a weight reduction diet.

Grapefruit Diet: Fact, Not Fiction

The grapefruit diet is not a myth. That’s what a new study by the Nutrition and Metabolic Research Center at Scripps Clinic confirmed. Researchers there found that the simple act of adding grapefruit and grapefruit juice to one’s diet can result in weight loss. The 12-week pilot study, led by Dr. Ken Fujioka, monitored weight and metabolic factors, such as insulin secretion, of the 100 men and women who participated in the Scripps Clinic “Grapefruit Diet” study. On average, participants who ate half a grapefruit with each meal lost 3.6 pounds, while those who drank a serving of grapefruit juice three times a day lost 3.3 pounds. However, many patients in the study lost more than 10 pounds.

Deze diëtistenpraktijk is echter met name gericht op het informeren van kankerpatiënten over voeding en het bewaken van een goede voedingstoestand tijdens alle fasen van het ziekteproces. Uit recent onderzoek is gebleken dat veel kankerpatiënten een grote waarde hechten aan voeding en een goede voedingstoestand, maar dat het vaak moeilijk is om hier informatie over te vergaren.Een goede voedingstoestand is geen garantie voor een grotere kans op herstel, maar het vermindert de kans op complicaties tijdens behandelingen en verhoogt de mate van herstel na een operatie en het algemene gevoel van welbevinden van de patiënt.

Uitstellen is heel menselijk. Ik geloof dat er nooit een "verkeerd" moment is om te beginnen je gewicht serieuze aandacht te geven - een gesprek over wat je (eigenlijk) zou willen kan de eerste aanzet zijn. Iedereen die op mijn spreekuur komt krijgt een voedingsadvies op maat; zoveel mogelijk aangepast aan je wensen en mogelijkheden. Misschien heb je aan dit voedingsadvies al voldoende houvast om af te vallen. Je komt dan voor een eenmalig consult. Of je kiest er bijvoorbeeld voor om eens per maand voor een kort bezoekje terug te komen, om "een stok achter de deur" te hebben en vragen te stellen over de dingen die je tegenkomt. Het kan ook zijn dat afvallen niet zo vanzelfsprekend gaat. Je hebt misschien al heel wat afgetobd met je gewicht, en "alles" al eens geprobeerd. Ik probeer je dan te helpen om jezelf te motiveren en geleidelijk die moeilijke obstakels uit de weg te ruimen. In dat geval kan je kiezen voor een langere en intensievere begeleiding.

Een eerste bezoek duurt ongeveer drie kwartier tot een uur. Hierin komen verschillende punten aan bod. Ten eerste een wederzijdse kennismaking. Vervolgens wordt altijd een voedingsanamnese afgenomen. Dit betekent dat u zo precies mogelijk probeert aan te geven wat u gewend bent om te eten, waar u van houdt en waar u een hekel aan heeft. Op deze manier kan ik de mogelijke veranderingen aangeven en in overleg met u in uw dagmenu inpassen. Ten slotte stellen we een behandelplan op en bespreken we het vervolg van de begeleiding .

Er zijn nog meer voorbeelden te noemen, maar waar het om gaat is..Wil je van je eetprobleem af dan zul je naar de oorzaken moeten kijken. En wat ik merk is dat mensen met een eetstoornis juist alles doen om maar niet met hun gevoelens bezig te zijn. Men wil wel de buitenkant veranderen zonder dat de binnenkant serieus genomen wordt. Dit zal niet werken.

Het lichaam laat je zien en voelen wat er aan de hand is, alleen luister je daar niet naar, ooit heb je ergens besloten daar afstand van te nemen. (Waarom?) Het lichaam vertelt wanneer het verzadigd is tijdens het eten, voel je dat of ga je overal aan voorbij. Voel je eigenlijk niets meer. Daarna komen de schuldgevoelens, ik ben weer eens zwak geweest, ik had juist de controle maar nu ineens niet. Je voelt je weer eens waardeloos, baalt van je lijf dat te dik is of waarvan je denkt dat het te dik is. (anorexia). Een vicieuze cirkel waarin je zult blijven hangen tot je de pijn van binnen zal erkennen. Misschien ben je teleurgesteld in je relatie, mis je contact. Misschien ben je teleurgesteld in je ouders en stop je dat weg omdat je hen niet de schuld wil geven.

Je mag waarschijnlijk toch al niemand de schuld geven. Wel jezelf. En ook mag je wel boos op jezelf zijn maar zeker niet boos op een ander.Mijn werkwijze met eetstoornissen bestaat uit een swingend bewegingsprogramma (groep) in combinatie met een praatgroep. Het bewegen is belangrijk om verschillende redenen. Het weer stevig maken van de spieren
