Frequently Asked Questions

Which DietXP calculator should I use first?

Start with the Smart Health Calculator for a complete overview of BMI, BMR, TDEE, and goal-based calorie and macro targets in one workflow. It is the most comprehensive starting point for any health goal.

Are these calculators accurate for Indians?

Yes. All tools use the Mifflin–St Jeor equation for BMR, Asian/Indian BMI classification (overweight ≥23, obese ≥25), and ICMR–NIN 2024 Dietary Guidelines for daily food group targets — making them specifically calibrated for the Indian population.

Can I use these tools for medical conditions?

The calculators provide general estimates based on validated clinical formulas. They are not a substitute for medical advice. Always review results with a qualified healthcare provider or certified dietitian, especially if you have diabetes, PCOS, thyroid disorders, or kidney disease.

What is the difference between BMR and TDEE?

BMR (Basal Metabolic Rate) is the calories your body burns at complete rest to maintain vital functions like breathing and circulation. TDEE (Total Daily Energy Expenditure) factors in your physical activity level and gives the total calories burned per day — used to set targets for weight loss, maintenance, or gain.

Why do DietXP calculators use Asian BMI cutoffs instead of the WHO standard?

South Asians carry significantly higher metabolic risk — type 2 diabetes and cardiovascular disease — at lower BMI values compared to Western populations. The Asian classification (overweight ≥23, obese ≥25) more accurately reflects health risk in Indians and is recommended by the API, RSSDI, and ICMR–NIN.

How often should I recalculate my calorie needs?

Recalculate every 4–8 weeks or after a body weight change of ±3 kg, a shift in activity level, or a change in health goal. Your BMR and TDEE change as your body composition changes, so regular recalculation keeps your targets accurate.
