Why Should You Know Your Body Fat Percentage?
Your health cannot be fully understood just from weight. Two persons weighing the same can have quite different body compositions. Comparatively to muscles, bones, and organs, body fat percentage shows your relative fat content. It guides you:
Track true fat loss—that is, not only muscular or water loss.
Check for metabolic problems, diabetes, and heart disease.
Specify reasonable bodybuilding or fitness targets.
Maintaining an ideal range will help you to perform in sports.
Sample Body Fat Calculation
Gender: male
Thirty years is the age.
Rising height: 175 cm
70 kg is weight.
Neck: forty-four centimeters
Waist: 85 cm
Body fat thus falls between 9.0% and Athlete’s range.
In this case, the user belongs to the “Athlete” category, meaning great lean body composition and fitness.
Percentage of Body Weight Categories:
Category | Men | Women |
---|---|---|
Essential Fat | 2–5% | 10–13% |
Athlete | 6–13% | 14–20% |
Workout | 14–17% | 21–24% |
Average | 18–24% | 25–31% |
Obese | 25% plus | 32% plus |
Knowing your category will enable you to create reasonable health goals. Either too high or too low a body fat percentage could compromise general well-being, hormone balance, and energy levels.
