Question 1

Is BMI accurate?

Accepted Answer

BMI is a reference, not an absolute standard — it cannot tell muscle from fat. Combine it with body-fat percentage and waist measurements.

Question 2

How do I lose weight healthily?

Accepted Answer

Aim for 0.5–1kg per week via a moderate calorie deficit from diet and exercise. Avoid crash diets; be patient and consistent.

Question 3

What's the difference between BMI and body fat?

Accepted Answer

BMI is weight over height squared; body fat is the share of fat in total weight. Two people with the same BMI can have very different body composition.

Question 4

Do BMI standards vary by age?

Accepted Answer

Adult standards are broadly consistent, with relaxed ranges for seniors. Children and teens use age- and sex-specific percentile charts.
