Clinical support tool based on ICMR-NIN 2024 guidelines with Indian phenotype BMR correction. Not a substitute for personalised antenatal dietitian advice. Women with GDM, pre-eclampsia, twin pregnancy or BMI extremes require individualised clinical management.
Age, Height & Pre-Pregnancy Weight * Mifflin-St Jeor BMR with 10% Indian phenotype correction (ICMR-NIN 2024). Reference body weight: 55 kg (Indian adult woman 19–39 y).
Current Trimester * ICMR-NIN 2024: T1 no extra calories. T2+T3: +350 kcal/day each. Protein additions are trimester-specific: T2 +9.5 g/day, T3 +22.0 g/day.
Physical Activity Level * ICMR-NIN 2024 PAL classification. Absolute targets (55 kg reference woman): Sedentary 1660 kcal, Moderate 2130 kcal, Heavy 2720 kcal/day (non-pregnant).

This calculator uses ICMR-NIN 2024 guidelines with Indian phenotype BMR correction. Outputs are population-level estimates: individual requirements may differ based on gestational complications, multiple pregnancy, medical conditions and measured metabolic rate. Always confirm nutrition targets with your antenatal dietitian, gynaecologist or obstetrician. Anaemia data from NFHS-5 (2019-21) and ICMR Aspirational Districts surveys represents population-level prevalence, not individual diagnosis.
