In a recent NY Times article, there are several quotes from scientists and nutritionists about calories, nutrition and the body's health. The whole article is here, a few excerpts below.
"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."
"100 calories of fat, protein and carbohydrates are the same in a thermodynamic sense, in that they release the same amount of energy when exposed to a Bunsen burner in a lab. But in a complex organism like a human being, he said, these foods influence satiety, metabolic rate, brain activity, blood sugar and the hormones that store fat in very different ways."
"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."
"Dr. Wang said that studies consistently show that sugary beverages, potato chips and other high-glycemic foods are indeed associated with weight gain. But this is because they are rapidly digested and easy to consume in large amounts, “not because they bypass our energy balance."
