  • A status with body weight that is above certain standard of acceptable or desirable weight. In the scale of body mass index, overweight is defined as having a bmi of 25.0-29.9 kg/m2. Overweight may or may not be due to increases in body fat (adipose tissue), hence overweight does not equal "over fat".
  • Being too heavy for one's height. Excess body weight can come from fat, muscle, bone, and/or water retention. Being overweight does not always mean being obese.
