Frequently asked questions
How is ideal weight calculated?
The estimate uses the Devine formula, a common clinical benchmark. The healthy range is derived from a body-mass index (BMI) of 18.5 to 24.9 for your height.
Is there one correct ideal weight?
No. "Ideal" weight varies with build, muscle, and age. Treat these as general reference points, not medical targets.
