Set point is a theory that says our metabolism will adjust itself to maintain the weight that is best for us. According to the theory, some people tend to have a naturally higher weight as a set point than others who have a naturally lower body weight.
The theory seems to be right. We all seem to have our best time - being most happy, most active and usually performance our best - at a certain weight. A perfect weight that is not too high and not too low for us. This body weight varies from person to person. While it is natural for some people to have fat on their bodies, others are thin and slim. And when we are getting too thin our body will try to gain weight again, and lose weight when we have eaten too much for a while.
