The main consensus concerning obesity and weight loss seems to be that it is all about the right diet and shear willpower. However that really may not be the case. There could actually be a genetic disposition that causes people to have trouble losing weight, keeping their appetite in check and causing them to overeat. This nature could be caused by a resistance to an important substance in the body called Leptin.
But what is Leptin? It is an influential protein in the body that is produced by human fat cells. It is responsible in communicating directly with the brain and tells the brain how much fat is stored in the body. It helps control your appetite, energy levels, hormone balance and metabolic rate.
