What is Body Fat Percentage?
Body fat percentage refers to the proportion of fat relative to your total body mass. For example, if your body fat percentage is 25%, it means that 25% of your body weight consists of fat, while the remaining 75% is muscle, bone, and other tissues. Understanding your body fat percentage is a key indicator of your fitness and overall health.
Ideal Body Fat Percentages for Men and Women
Generally, the healthy body fat range varies by gender:
- Men: 8-19%
- Women: 21-33%
However, this range can vary based on age, activity level, and fitness goals. Lower levels of body fat can be common in athletes, while slightly higher levels may still be healthy depending on an individual's body type and lifestyle.

The Importance of Body Fat for Your Health
Body fat, scientifically termed "adipose tissue," serves essential functions beyond just being an energy store. It:
- Stores lipids for energy production
- Secretes hormones that regulate metabolism
- Provides cushioning for internal organs
- Insulates the body, helping to maintain body temperature
There are two types of body fat:
- Essential Fat: This is the minimal amount of fat necessary for life and reproduction. For men, essential body fat ranges between 2-5%, while for women, it's typically between 10-13%.
- Storage Fat: This is the extra fat stored in adipose tissue, primarily found around internal organs. It's responsible for the excess fat that accumulates in areas such as the abdomen.
