BMI → Calories → Nutrition → Hydration
Start with a basic measurement, estimate energy needs, then use the Indian food planner to turn the numbers into a practical daily meal plan.
Understanding Your Health Numbers
BMI, body fat percentage, calorie needs, hydration and sleep timing answer different questions. Use the calculators as estimates and look at the assumptions behind each result rather than treating one number as a diagnosis.
BMI vs Body Fat % — Why Both Matter
BMI is a quick screening tool that uses only weight and height. A muscular person and someone with high body fat can have identical BMIs but very different health profiles. Body fat percentage directly measures what matters for health risk — the proportion of fat versus lean mass. Use BMI for a quick check; use the body fat calculator for a more accurate assessment.
Calories, BMR and TDEE
BMR estimates energy use at rest, while TDEE adds an activity assumption. A calorie target should be treated as a planning estimate, not a prescription. The Nutrition Calculator lets you connect TDEE estimates with real Indian food portions and meal totals.
Indian-Specific Health Considerations
South Asians develop weight-related health risks at lower BMI values than Western populations. The WHO has recommended slightly lower BMI thresholds for Indians: Normal weight is 18.5–22.9 (vs 18.5–24.9 globally), Overweight is 23–24.9, and Obese is 25+ — lower than the global 30+ threshold. Our BMI calculator uses these India-specific ranges.
Health estimates are informational. Where an Indian-specific threshold or method is shown, check the linked calculator's source and methodology notes.
Health Calculator FAQs
How should I use these health calculators?
Use them as estimates for understanding common health metrics. Enter your measurements, review the assumptions, and compare related results rather than treating one number as a diagnosis.
What is the difference between BMI and body fat percentage?
BMI uses height and weight to provide a screening measure. Body fat percentage estimates the proportion of body weight that is fat. They answer different questions and can give different signals.
How do BMR and TDEE help with calorie planning?
BMR estimates energy use at rest. TDEE adds an activity assumption to estimate daily energy needs. These are planning estimates, not individualized medical prescriptions.
Can I calculate calories for Indian food?
Yes. The Indian Food Calorie & Nutrition Calculator covers 145 curated foods, portion sizes, calories, protein, carbohydrates and fat, plus a daily meal planner.
Is the water intake result a medical recommendation?
No. Hydration needs vary with body size, activity, climate, diet and health conditions. The calculator provides a general estimate and should not override advice from a healthcare professional.
