よくある質問
What is a healthy body fat percentage?
For men, the fit range is 14–17% and athletic is 6–13%. For women, fit is 21–24% and athletic is 14–20%. Essential fat (required for basic physiological function) is 2–5% for men and 10–13% for women. Above 25% (men) or 32% (women) is generally considered obese.
How accurate is the US Navy body fat method?
Typically accurate to within 3–4 percentage points of DEXA scan measurements, making it one of the best practical field methods available. Measurement technique matters — measure in the morning while relaxed, take three readings, and average them for best accuracy.
How can I reduce my body fat percentage?
A sustained calorie deficit through a combination of diet and exercise is the most effective approach. Strength training preserves muscle mass during the deficit, improving your body composition ratio. Aiming to lose 0.5–1% of body weight per week is a sustainable and manageable rate.
What is the difference between body fat percentage and BMI?
BMI only considers height and weight — it ignores body composition entirely. Two people with the same BMI can have very different body fat percentages. An athlete with high muscle mass may have a high BMI but low body fat, while a sedentary person may have normal BMI but high body fat ("skinny fat").
