Oftentimes, doctors, nurses, and other professionals will put your weight in terms of your height and gender in a figure called body mass index (BMI). Obesity means that someone has an excess amount of fat to the extent that it harms your health. The bulk of this mass is from body fat, water, muscle, and bone.
