Here is the article that talked about the movie Fed Up. In addition to describing the movie, there are some excerpts that endorse low-carbohydrate/high protein diets, which some friends have been describing as paleo/caveman diets: eat like a caveman…nothing that is from cultivated, starchy products, like potatoes, grains, bread, etc.
Are all calories equal?
Dr. David Ludwig, the director of the obesity program at Boston Children’s Hospital, argues in the film that they are not. In recent studies, Dr. Ludwig has shown that high-carbohydrate diets appear to slow metabolic rates compared to diets higher in fat and protein, so that people expend less energy even when consuming the same number of calories. Dr. Ludwig has found that unlike calories from so-called low glycemic foods (like beans, nuts and non-starchy vegetables), those from high glycemic foods (such as sugar, bread and potatoes) spike blood sugar and stimulate hunger and cravings, which can drive people to overeat.
Studies also show that calories from different foods are not absorbed the same. When people eat high-fiber foods like nuts and some vegetables, for example, only about three-quarters of the calories they contain are absorbed. The rest are excreted from the body unused. So the calories listed on their labels are not what the body is actually getting.
I am still convinced that if you eat less and exercise more, most people will feel better and lose weight. Now that it appears if you eat less carbohydrates you will lose even MORE weight, that should make it easier to see lower numbers on your scale.
