Frequently asked questions
- What is BMI Prime?
- BMI Prime = your BMI ÷ 25. It was proposed to provide a single number that scales linearly around the healthy-overweight threshold. Prime <0.74 = underweight; 0.74–1.00 = healthy; >1.00 = overweight/obese.
- How does BMI Prime differ from regular BMI?
- BMI Prime is just BMI rescaled so that 1.0 = the top of the healthy range. It carries the same limitations as BMI (doesn’t account for muscle, fat distribution, age, or ethnicity).
