Why existing efforts to combat childhood obesity are bound to fail. By Gary Taubes | hi... - 0 views

  • For the last 60 years, physicians and public-health authorities have been giving that exact same advice to obese people—children and adults—with little or no success
  • The subjects experience modest weight loss (maybe nine or 10 pounds in the first six months), and then they gain the weight right back. Weight loss doesn't last
  • The researchers enrolled nearly 50,000 mostly overweight or obese women into the trial, chose roughly 20,000 of them at random, and instructed that group to eat a low-fat diet, rich in fruits, vegetables, and fiber. These women were given regular counseling to motivate them to stay on the diet. If we believe what these women said they were eating, they also cut their average energy intake by well more than 300 calories a day

  • After seven-plus years on the diet, these women lost an average of one pound each6 (PDF). And their average waist circumference—a measure of what the diet-book authors like to call "belly fat"—increased
  • whatever weight these women lost was not fat but lean tissue—muscle
  • Prior to the 1960s, clinicians used to argue that making an obese person exercise would just make them hungry—they'd work up an appetite—and that's the last thing you want for someone who needs to lose weight.
  • but it certainly speaks to the idea that getting kids to move more is not the answer
  • Making it possible for children to enjoy the benefits of physical activity is a wonderful thing, but expecting that they'll lose weight by doing so is naive
  • how the human body regulates fat metabolism and the accumulation of fat in our adipose tissue
  • why we accumulate fat—or more specifically, why our fat cells store more calories as fat than they release into the circulation to be burned for fuel
  • Insulin levels, for all intents and purposes, are controlled by the carbohydrates in the diet. The more refined and easily digestible those carbohydrates (the higher the glycemic index, as nutritionists would say), the more insulin will be secreted. And the sugars we consume—i.e., sucrose, the stuff we put in our coffee, as well as high-fructose corn syrup—will cause long-term increases in insulin production
  • Every woman knows carbohydrate is fattening: this is a piece of common knowledge, which few nutritionists would dispute
  • We have to tell children (and their parents) that carbohydrate-rich foods—especially sugars and liquid sugars, like fruit juice and soda—are literally fattening.

Americans Are "Sickeningly Sweet" - 0 views

  • Babies and Beverages – “A study from the American Journal of Clinical Nutrition found that reduction in sugar-sweetened beverages (regular soda, fruit drinks and fruit punch) had a significant effect on weight change at 6 months and 18 months, even more of an impact than solid- calorie reduction.”
  • Liquid caloric consumption can be quite a significant contribution to weight gain so this is a tremendous effort to educate the public,” said Dr. Bartfield

  • Take Michelle Obama's Let's Move! campaign, one of the most high-profile examples of this mistaken approach to the problem. The principles of Let's Move! sound good. Who would be against getting kids to be more physically active and eat more fruits and vegetables? But anyone who thinks that will reverse the obesity epidemic is sorely mistaken

High Fructose Corn Syrup (HFCS) Is Fine In Moderation… Wait, What?! - 0 views

  • HFCS has been shown to interfere with a key enzyme in the body that delivers copper to your vital organs. This effectively results in copper deficiency for many, adversely impacting a wide range of organ systems including the heart, testes, pancreas, and damaging the liver-generating inflammation and cirrhosis. It has been strongly linked to the sharp rise in both obesity and diabetes. Furthermore, fructose is 20-30 times more gylcating than glucose. It turns anyone into a raging AGE-producing factory. Animals fed a high-fructose diet in laboratory studies developed livers that looked a lot like those of hardcore, aging alcoholics-inflamed and shot through with dead cells and scar tissue-the condition known as “cirrhosis.”

Fructose - Wikipedia, the free encyclopedia - 0 views

  • produced significantly higher fasting plasma triacylglycerol values than did the glucose diet in men
  • This may be an important contribution to senescence and many age-related chronic diseases
  • When fructose reaches the liver," says Dr. William J. Whelan, a biochemist at the University of Miami School of Medicine, "the liver goes bananas and stops everything else to metabolize the fructose." Eating fructose instead of glucose results in lower circulating insulin and leptin levels, and higher ghrelin levels after the meal.[59] Since leptin and insulin decrease appetite and ghrelin increases appetite, some researchers suspect that eating large amounts of fructose increases the likelihood of weight gain

What makes fructose fattening? Some answers found in the brain - 0 views

  • the brain's response to fructose is very different to the response to glucose, which is less likely to promote weight gain
  • This study provides evidence in humans that fructose and glucose elicits opposite responses in the brain. It supports the animal research that shows similar findings and links fructose with obesity

Consumo de azúcar y salud cardiovascular | EROSKI CONSUMER - 0 views

  • Los estudios epidemiológicos han evidenciado que una dieta baja en lípidos (20% o menos del total de energía diaria) y rica en hidratos de carbono (sobre todo, en azúcares simples) puede provocar cambios metabólicos que deriven en dislipidemia aterogénica, diabetes tipo 2 y síndrome metabólico.
  • La Asociación Americana del Corazón (AHA) ha advertido sobre los efectos para la salud de la creciente ingesta de azúcares que se constata en la población. Las consecuencias asociadas van desde anomalías en el metabolismo de los lípidos, la glucosa y el peso, hasta déficits de nutrientes esenciales
  • En España, el consumo total de azúcares simples por persona y día es de unos 120 g (entre 15 y 20 cucharaditas de postre al día), frente a los 55 g máximos recomendados

  • La mayoría de estos azúcares procede de productos elaborados, como bebidas azucaradas, cereales y derivados lácteos, según el informe "Valoración de la dieta española de acuerdo al Panel de Consumo alimentario" de 2006, realizado por la Fundación Española de la Nutrición (FEN)
