If the enemy was not the calories, but carbohydrates ?

And if all that was thought out plans for years was wrong? If Cal was not the number 1 enemy of overweight ?

Since 1878, studies of the great German Max Rubner nutritionist, calorie is fighting to avoid cluttering. The question monopolize the debate on how to lose weight: ingurgitons us more calories than we expend calories or they are poorly distributed and obesity is she a bad "fat storage"?
Dr. Ludwig has gone further and has just published a controversial study in the Journal of the American Medical Association showing that calories have nothing to do with gaining or losing significant weight.

Twenty-one obese people have been semi-diet until they lost 10% to 15% of their weight. They were therefore more likely to return the lost pounds quickly. They then followed three different diets for one month each. The first was so low in fat and rich in carbohydrates (whole grains, fruits, vegetables ...). The second had a low glycemic index, and the little that was present was slow to digest (from the bean among others). The third was the Atkins diet very low in carbohydrates but high in protein.



The NY Times has published and commented edifying results. In the very low-carbohydrate diet, the subjects of Dr. Ludwig spent twice more calories per day than the low-fat diet. In the latter, they had to add a quarter of an hour of physical activity each day to spend much energy they did effortlessly with a diet very low in carbohydrate.
To summarize, in this study we eat less carbohydrates, more easily we remain slim. More carbohydrates we consume, the more difficult it is.

These results completely contradict the advice that we give the government and most health organizations: eat less fat, more carbohydrates even though these diets contain whole grains, fruits and vegetables.

If this remains controversial study, Dr. Ludwig wants to repeat the experience, this time with more subjects, and in the long term.

But the dark side of the carb is also found in another study published in the Archives of Internal Medicine. The latter showed that women who consumed too many simple carbohydrates were more likely to develop heart disease than others.
