Body types: what really changes, and what does not

What the three body types say, and do not say

The classic categories, ectomorph, mesomorph, endomorph, describe an appearance. They determine neither your exact metabolism nor your capacity to lose fat.

What is true: people differ in fat distribution, limb length, bone density, carbohydrate tolerance, spontaneous appetite and NEAT.

What is false: that a category condemns you to an outcome. A calorie deficit works in every case. What changes is the rate and the ease.

The four parameters that justify an adaptation

One. The starting body fat level. The higher it is, the more aggressive the deficit can be at the start, and the faster the early results. Someone at thirty-five per cent body fat can hold a seven-hundred-kilocalorie deficit; someone at fifteen per cent should stay around three hundred.

Two. Training history. A beginner gains muscle in a deficit, which is called recomposition. Someone who has trained for five years has to settle for preserving.

Three. Fat distribution, which is genetic and not a matter of choice. Abdomen first in many men; hips and thighs in many women. You cannot lose fat locally. The last areas to empty are the ones that filled first. No abdominal exercise removes belly fat.
