Body Fat Percentage & Health

Body fat percentage is one of the best measures of health. It’s much better than Body Mass Index (BMI). This is becasue BMI doesn’t take above normal levels of muscularity into consideration, and it also discriminates if you’re very short or tall.

Body Fat Percentage & Bulking/Cutting Cycles

If your goal is to get lean and muscular, then the quickest and most effective way towards such a physique is by doing cutting and bulking cycles.

For cutting and bulking cycles to work well, both when it comes to results and health, you should do them within a certain body fat percentage range.

Optimal Cutting/Bulking Body Fat Percentage Range For Men:

8-15 % body fat

Optimal Cutting/Bulking Body Fat Percentage Range For Women:

18-25 % body fat

Body Fat Percentage & Optimal Caloric Deficit

If your goal is fat loss, then setting up your caloric deficit correctly is extremely important. If your deficit is too large you’ll start losing muscle mass and experience other unpleasantries, both physical and psychological.

On the other hand, if you keep your deficit too small, then fat loss will happen very slowly.

There’s a theoretical limit to how much fat that can be released from the fat stores in a single day, where any additional weight lost above this limit will be muscle mass, no matter how high the protein intake is.

This limit is inversely proportional to how lean we are, meaning that the leaner we get, the smaller the deficit must be.

That’s why the best way to set up your caloric deficit is based on your body fat percentage:
