Genetic and Obesity
Genetic factors play an important role in determining the traits of obesity and also rate of weight loss. Some genes play the role to telling the body how to metabolize food and to use extra calories or stored fat. Obesity runs in families as generally families eat similar foods, have similar lifestyle habits and thinking patterns, such as that children should eat more to become big and healthy. Certain illnesses like thyroid gland problems or genetic diseases run in families.
Some eating disorders like binge eating disorder affect a person's diet as he eats more and repeatedly often in binges. These people generally lack the developed eating patterns learned in childhood.
It is also to be remembered that obesity is not the result of momentary overeating. It is a long term phenomenon because people tend to overeat over long periods of time.
Emotions can fuel obesity, as people tend to eat more when they are upset, anxious, sad, stressed or even bored. Afterwards they feel bad about eating more, and later to relieve this stress, they may eat even more.
