1. What is Body Fat Percentage?
Body fat percentage is the amount of fat in your body compared to your total body weight. It is a better indicator of health and fitness than body weight alone because it shows how much of your body is made up of fat tissue.

Healthy body fat ranges vary by gender and age. Generally, men should have around 10–20% body fat, while women should have around 18–28% body fat for good health.
3. Is Body Fat Percentage more accurate than BMI?
Yes. Body fat percentage is generally more accurate than BMI because it measures the actual proportion of body fat instead of only comparing height and weight.
