FAQ
What is BMI?
Body mass index is a height to weight ratio that helps flag possible weight related health risks.
Is BMI the same as body fat?
No. BMI is a screening number. Pair it with other health markers like strength, waist size, and lab work.
What if I lift heavy?
Muscle can push BMI higher without adding fat. Use the healthy weight range as a guide, not a rule.
