A human hormone, combined with a full stomach, offers clues for understanding our food intake
...ackground CCK is a hormone released when digested fats and proteins are present, and reduces food intake. CCK stimulates enzyme secretion in the pancreas. The process eventually leads to inhibiting gastric emptying of the stomach's foods, thereby causing gastric distension. It has been suggested that in...Atkins diet may reduce seizures in children with epilepsy
...structed to increase calorie intake by eating more fats and proteins. In the Hopkins study, patients began with 10 grams of carbohydrates per day, more than the typical amount provided on the ketogenic diet, but fewer than used in the induction phase of the Atkins diet (20 grams/day). Carbohydrate intake...Study finds huge variability in vitamin E absorption

...dase, which results in the accumulation of certain fats (gangliosides) in the brain and other organs of the body. Mice deficient in the Hexb gene have provided a useful model system in which to study this human disorder.
