There are several factors that determine the weight of the person.
First is the genetic background. Genes put basic characteristic on the body’s metabolic efficiency. Genes governing metabolism run in families. If one of your parents is overweight you are more likely to be overweight that other whose parents are normal weight. If both of your parents are overweight then there’s a high risk that you will be overweight.
Second is the metabolic rate. People’s metabolic rates are largely determined by how active they are. Muscle tissue more active than fat and if you will be in active your muscle will density will decrease and your fat will increase.
Third factor is the eating pattern. Eating food which have high fat and high calorie will much likely to increase weight. Eating a large amount of food would also increase the risk of gaining weight.
Last factor is exercise. Exercise is the essential component of weight program. People who have less or no exercise at all will decrease their muscle tissue and fat tissue thus they gain weight gradually.
