About MyNutrients
India's free nutrition toolkit — built for accuracy, privacy, and Indian dietary reality.
What we are
MyNutrients is a free, browser-based nutrition tool suite built specifically for Indian users. There's no signup, no personal data collection, and no accounts required. Every calculation happens entirely in your browser — we never see your inputs or results.
We built 7 tools: a macro calculator, BMI checker, calorie deficit planner, water intake calculator, protein calculator, meal tracker, and a searchable Indian food database with 200+ foods.
Why we built it
Most popular nutrition apps — MyFitnessPal, Cronometer, and others — were built primarily for Western diets. Their Indian food entries are often inaccurate, missing, or use generic values that don't reflect how Indians actually cook and eat.
More critically, these apps use Western BMI standards. A BMI of 24 might be "normal" on a Western chart — but for South Asians, it's associated with significantly higher cardiometabolic risk. Indians are predisposed to visceral fat accumulation at lower BMI values than European populations.
MyNutrients fixes both: accurate Indian food data and Asian-appropriate health thresholds.
Our data sources
- IFCT 2017 — Indian Food Composition Tables, published by the National Institute of Nutrition (NIN), Hyderabad. The most comprehensive and authoritative source for Indian food nutritional data.
- NIN India — National Institute of Nutrition dietary guidelines and recommended dietary allowances for Indians (ICMR-NIN 2020).
- WHO Expert Consultation, 2004 — "Appropriate body-mass index for Asian populations and its implications for policy and intervention strategies." Lancet, 363(9403), 157–163.
- Mifflin-St Jeor (1990) — Gold-standard BMR formula validated for diverse populations and preferred over the older Harris-Benedict equation.
How the calculators work
Macro Calculator
Uses the Mifflin-St Jeor equation for BMR, multiplied by an activity factor to get TDEE. Protein at 1.8g/kg, fat at 25% of calories, carbs fill the remainder.
BMI Calculator
Standard BMI formula (kg/m²) with WHO Asian cut-offs: ≥23 = overweight, ≥27.5 = obese. Significantly different from Western thresholds (≥25, ≥30).
Calorie Deficit
Uses the 7,700 kcal/kg rule for fat loss estimation. Enforces a 1,200 kcal/day minimum safety floor and flags deficits above 750 kcal/day as aggressive.
Water Intake
Base: 33 ml/kg body weight, with additions for activity level (+0 to +1.05L) and Indian climate zone (+0 to +0.75L for coastal/humid regions).
Protein Calculator
Multipliers from 0.8g/kg (sedentary) to 2.2g/kg (bodybuilding), aligned with ICMR-NIN 2020 and international sports nutrition research.
