FAQ
Why do the formulas give different results?
Each formula was developed for a specific clinical purpose at a different time. The differences reflect varying assumptions about ideal body composition and the populations studied.
Are these formulas suitable for athletes?
Not entirely — these formulas don't account for muscle mass. A muscular athlete may weigh more than the formula suggests while still being healthy. Use body fat percentage as a complementary measure.
