Some research shows that our body has a natural weight or “set point” that it will return to regardless of what we eat and how much exercise we do. Some scientists think that the body has a fixed weight and that metabolism, hormones and the brain will adjust to maintain that weight. By nature, people may have a higher or lower fixed weight than others; their set points may be affected by genetics, aging, a history of weight loss, and hormonal changes. The theory suggests that nominal weight may increase, but rarely decrease. It's easier to keep your weight fixed because your body wants to stay at that point, not lose weight.
