Energy balance

Mathematical models of body weight regulation show that the caloric equivalent of lost weight is not constant but depends nonlinearly on initial body fat mass.

The number of calories you need to cut to lose a pound of weight changes as you lose weight, especially if you start with a higher body fat percentage. Fatter individuals need to create a larger caloric deficit to lose the same amount of weight compared to leaner individuals.

A recent mathematical model showed that the caloric equivalent of lost weight is not a constant but rather depends nonlinearly on initial body fat mass, with fatter individuals requiring more calories to lose the same amount of weight.
