How It Works
BMR estimate=10×kg+6.25×cm−5×age+(5 male or −161 female). Maintenance estimate=BMR×selected activity multiplier.
The activity factors are heuristic scenarios, not measurements. This tool estimates maintenance and does not prescribe a calorie deficit.
Scope and Limitations
- For nonpregnant adults aged 20–78 within the entered measurement ranges. Individual energy expenditure can differ substantially; not a substitute for measured calorimetry or clinical nutrition assessment.
