FAQs

What is a healthy body fat percentage for men?

What is a healthy body fat percentage for women?

Common ACE-style body fat categories for women are: 10–13% essential fat, 14–20% athletes, 21–24% fitness, 25–31% average/acceptable, and 32% or higher obese range.

Is very low body fat risky?

Yes. Very low body fat can be risky because the body needs essential fat for hormone function, organ protection, temperature control, and normal health. Extremely low values should not be treated as a fitness goal without professional guidance.

Is body fat percentage better than BMI?

Body fat percentage can give more detail than BMI because it estimates how much of your weight is fat. BMI is useful for quick screening, while body fat percentage is better for tracking body composition changes.
