A clinical estimate of your healthy weight range, not a number to chase, but a sensible baseline.
Based on Devine, Robinson and Hamwi formulas
Ideal Body Weight (IBW) is a clinical estimate of the weight associated with the lowest mortality risk for a given height and sex. It originated in the 1970s for medication dosing and is still used today in critical care, dialysis and nutrition support.
The three classic formulas, Devine (1974), Robinson (1983) and Hamwi (1964), all start from a baseline at 5 feet (152 cm) and add weight per inch above that. They differ slightly in the per-inch increment, which is why we report a range rather than one number.
Think of the range as a healthy neighbourhood, not a strict target. Two things to keep in mind:
If you're well above the range, our weight-loss program can help bring you down sustainably. If you're well below, our healthy weight-gain program can help you rebuild safely.
Use your IBW range to back-calculate sensible nutrition targets: most adults need 25-30 kcal per kg of IBW for maintenance, 1.2-1.6 g/kg of protein for general health, and 2.0-2.2 g/kg if you're actively losing fat or building muscle.
If you're moving toward this range, up or down, the rate matters more than the destination. Aim for 0.5-1% of body weight per week in either direction; faster than that and you risk losing muscle (cutting) or gaining fat (bulking).
This calculator is most useful if you're working on:
Nutrient-dense plans for lean, healthy weight and muscle gain.
Structured programs for sustainable fat loss with balanced Indian meals.
Knowing your range is step one. Step two is a weekly meal plan that gets you there without crash dieting or weight cycling. Book a free consultation to map it out.
