Overweight vs. Overfat (and the Metropolitan Life Tables)
0% read · 1 min left
"Overweight" is defined against standard weight tables, but the percentage of weight that is fat ("overfat") is a far more meaningful measure of health.
Detail
The difference between being overweight and being overfat is an important distinction. Overweight is frequently defined as 10% in excess of the midpoint of the normal body-weight range in the Metropolitan Life Insurance tables. Unfortunately, this definition does not consider the amount of body fat.
Regarding relative leanness for positive health, the percentage of a person's body weight that is fat is far more meaningful than scale weight. Women and men are obese if they possess greater than 32% and 25% body fat, respectively (see obesity-thresholds).
Key facts
- Overweight ≈ 10% above the midpoint of the normal weight range in the Metropolitan Life Insurance tables.
