Healthy weight ranges from four classic formulas plus the normal-BMI band for your height.
Devine: 50 kg + 2.3 kg per inch over 5 ft (men); 45.5 + 2.3 per inch over (women)
A 175 cm (5'9") male gets estimates from roughly 63 kg (Robinson) to 71 kg (Devine).
Each formula was designed for a different purpose (drug dosing, insurance tables) so they disagree by several kilograms. Treat the spread as a range rather than a single target, and weigh it against body composition and how you feel.
No — healthy weight is a range influenced by muscle mass, bone structure and health markers, not a single number.
Daily calorie targets for losing, maintaining or gaining weight based on your goal pace.
Body Mass Index in metric or imperial units, with WHO category and healthy weight range for your height.
Estimate your 1RM from a rep max set, plus percentage-based training loads.
Basal Metabolic Rate via the Mifflin-St Jeor equation — the calories your body burns at complete rest.
Total Daily Energy Expenditure: your full-day calorie burn based on BMR and activity level.
Protein, carb and fat gram targets matched to your calories and preferred macro split.
