Frequently Asked Questions
How is ideal weight estimated?
It uses established formulas based on your height and sex to suggest a healthy weight range, not a single fixed number.
Is there one perfect ideal weight?
No. Frame size, muscle and body composition mean a range is more realistic than a single target.
How does ideal weight relate to BMI?
Both aim at a healthy range, but ideal-weight formulas focus on height and sex while BMI factors weight against height directly.
