The Science Behind Losing Weight on a High-Protein Diet

A brain signal system that controls appetite responds to specific amino acids found in meat. This discovery could lead to new weight-loss techniques.LeucineAnimals injected with the amino acid leucine ate 20 percent less food the following day, and only gained a third of the weight of their peers after a 24-hour fast. Leucine, which is found in protein-rich foods, acts on the enzyme mTOR. mTOR is highly active in a brain structure called the hypothalamus, which regulates appetite.Fooling the BrainThe leucine may fool the brain into believing there is an ample protein supply throughout the body, resulting in a suppression of hunger.
