Question 1

What is a healthy BMI?

Accepted Answer

A BMI between 18.5 and 24.9 is considered healthy for most adults. Values below 18.5 indicate underweight, 25–29.9 is overweight, and 30 or above is classified as obese. BMI is a screening tool — it does not account for muscle mass or body composition.

Question 2

How many calories should I eat to lose weight?

Accepted Answer

A daily deficit of 500 calories typically leads to around 0.5 kg of weight loss per week. Use the calorie calculator above to find your maintenance level, then subtract 500. Avoid going below 1,200 kcal per day without medical supervision.

Question 3

What activity level should I choose?

Accepted Answer

Choose "Sedentary" if you have a desk job and rarely exercise. "Light" fits 1–3 casual workouts per week. "Moderate" is for 3–5 structured sessions. "Active" applies if you train 6–7 days. "Very Active" is for athletes or people with physically demanding jobs.

Question 4

Is the BMI calculator accurate for athletes?

Accepted Answer

No. BMI can misclassify muscular individuals as overweight because it only uses height and weight. For athletes, body fat percentage or waist-to-height ratio are more reliable metrics. Use BMI as a general reference, not a definitive measure.

Question 5

How often should I recalculate my calorie needs?

Accepted Answer

Recalculate every 4–6 weeks or after a 3–5 kg change in body weight. As you lose or gain weight, your maintenance calories shift. Regular recalculation keeps your targets accurate.
