FAQ
Frequently asked questions
Is BMI reliable for everyone?+
No. It's less relevant for muscular athletes (high BMI without excess fat), pregnant women, children and the elderly.
My BMI is normal but I have a belly — is that worrying?+
Abdominal fat (waist > 94 cm men / 80 cm women) is a cardiovascular risk factor independent of BMI. Consult a doctor.
How can I lose weight safely?+
Lose at most 0.5 to 1 kg/week, through a balanced diet and 150 min of activity per week. A nutritionist can tailor your plan.
Does BMI change with age?+
Yes. After 65, a slightly higher BMI (25–27) is protective against undernutrition and falls.
