Healthy weight range
Weight range by BMI 18.5–24.9 (WHO) plus Devine and Hamwi ideal body weight for drug dosing.
About this calculator
Healthy weight range is calculated from BMI 18.5-24.99 (WHO Technical Report Series 854, 1995). Formula: lower bound = 18.5 × height (m)², upper bound = 24.99 × height (m)². Example: at 170 cm height the range is 53.5-72.2 kg. WHO classification. BMI <18.5 – underweight. 18.5-24.99 – normal. 25-29.99 – overweight. >=30 – obesity. Clinical use. Educational goal – show the patient a weight range corresponding to minimal cardiometabolic risk. Used in primary care, endocrinology, dietetics to motivate weight management. Weight loss target – 5-10% of baseline over 6 months in overweight patients, reducing T2DM risk by 58% (Diabetes Prevention Program, NEJM 2002). Ethnic specifics. For Asian populations thresholds are lower: lower 18.5 × height², upper 22.99 × height² (WHO Expert Consultation 2004). In Indian, Chinese, Southeast Asian patients metabolic abnormalities develop at lower BMI. Limitations. BMI does not distinguish muscle from fat. In high-muscle athletes the calculated "healthy range" may falsely appear as overweight. In sarcopenic older patients normal BMI may hide visceral obesity. Add waist circumference (men <94 cm, women <80 cm) and body composition (DEXA, bioimpedance).
