Ideal Body Weight: How to Find Your Healthy Weight
Ideal weight isn't one number, it's a range. Two people at the same height and weight can look and feel completely different depending on muscle and fat.
A quick ideal weight formula
Men: (height in cm − 100) − 10%. Women: (height in cm − 100) − 15%. A 175cm man lands around 67kg, a 165cm woman around 55kg. Treat it as a starting point, not a verdict.
Body Mass Index (BMI)
BMI = weight ÷ (height in metres)². Under 18.5 underweight, 18.5-24.9 normal, 25-29.9 overweight, 30+ obese. Its flaw: a muscular lifter reads as 'overweight' because BMI can't tell muscle from fat.
The honest metric: body fat
Men: 10-18% is healthy and athletic; women: 18-26%. Track waist circumference and photos every four weeks — far more reliable than a scale number that swings daily with water and salt.
