Document Summary
The body stores excess calories as fat in adipose tissue: consists of cells that vary in number and size. First, people often put on weight at certain times, without taking it all off, and the balance accumulates across the years. Second, physical activity and metabolism decline with age. The body mass index of parents and their offspring are related. Fto: feeling of satiation and developing adipose tissue. Mc4r: preferring and consuming high amounts of dietary fat. Heredity is not destiny and we don"t know how many people have genes that promote weight gain or how much of their excess weight results from these genes. Set point theory: each person"s body has a certain or set weight that it strives to maintain. Ghrelin: secreted and carried in the body when energy intake is low or the stomach is empty. Leptin: regulates circuits in the hypothalamus and stimulate and inhibit eating and metabolism.
