Frequently asked questions
Is BMI accurate for everyone?
BMI is a useful population screen but cannot tell muscle from fat, so it overstates risk for muscular builds. Pair it with the Body Fat calculator and waist measurement for a fuller picture.
How many calories should I eat a day?
Use the Calorie Calculator — it estimates your total daily energy needs (TDEE) from your BMR and activity level, then sets targets for losing, maintaining or gaining weight.
