Body Fat Percentage

In PeakWatch, Body Fat Percentage refers to the proportion of fat weight in your total body weight. Compared to BMI, it more directly reflects your body composition and is a key indicator for judging whether your body shape is healthy.

Why Focus on Body Fat Percentage?

The numbers on the scale cannot distinguish between muscle and fat. Knowing your body fat percentage helps you clarify whether you are really losing fat when losing weight. Fat plays an important role in the body, including providing energy reserves, protecting internal organs, and maintaining normal hormone secretion.

PeakWatch Evaluation Standards

Men and women have different physiological structures, so the healthy range for body fat percentage also differs:

Men

• Low: Below 10%
• Standard: 10% to 22%
• High: Above 22%

Women

• Low: Below 10% (Note: Women have higher essential fat, it is recommended to maintain above 13%)
• Standard: 10% to 20%
• High: Above 20%

Lower is Not Always Better

Extremely low body fat percentage is usually a goal for professional athletes during specific seasons, but it does not necessarily mean better health. If body fat percentage is too low for a long time, it may lead to decreased immunity, physical fatigue, or endocrine disorders.

Limitations of the Indicator

Looking at body fat percentage alone also has its limitations. For example, a person with a low body fat percentage may still appear to lack strength and have a slow metabolism if their muscle content is also very low (i.e., insufficient Fat-Free Mass). Therefore, we suggest you observe it together with FFMI (Fat-Free Mass Index). Only by maintaining muscle mass while controlling body fat can you achieve the ideal body state.
