Obesity is a chronic medical condition that often leads to high blood pressure, heart disease, diabetes, and other serious diseases. Lately, within short period of time, it became an epidemic around the world. Obesity must be treated, because it can be life-threatening. According to the latest statistics, in 2016 more than 1.9 billion adults were overweight, and 13% of them were obese. Although there are mainly genetic and hormonal influences on body weight, obesity can come as a result of overeating. When one takes more calories than he burns, the body stores the excess calories as fat.
