In the chromosomes are genes responsible for producing leptin, a substance through the blood reaches the hypothalamus, the satiety center in order to cause loss of appetite and stimulate the sympathetic nervous system responsible for energy consumption. If these genes are altered, leptin does not occur in the correct proportion, in these cases, people are encouraged to continue eating more than you would in normal conditions
Diseases:
Hormonal imbalances are the cause of overweight and obesity, such as hypothyroidism, polycystic ovary syndrome and Cushing’s syndrome.

The reason for this is because the hormones released during sleep control appetite and energy use in the body, in addition, those who do not usually get enough sleep, seem to have a higher concentration of hormone called ghrelin is responsible for increasing appetite and low concentrations of leptin that controls appetite in people
Neuroendocrinological:
They are produced in the body of some kind for problems such as obesity due to the hypothalamus, deficiency in growth hormone, hypothyroidism, among others.
