What is ideal body weight?
Ideal Body Weight is the optimal weight correlating with the best health outcomes and lowest mortality risk. Factors influencing IBW include gender, age, muscle-fat ratio, body shape, and frame size.

The American Society of Anesthesiologists provides gender-specific formulas:

  • Men: 50 + (0.91 × [height in cm – 152.4])

Ideal Body Weight vs. BMI
While BMI offers a quick weight health assessment, IBW provides a more accurate health estimation. BMI is a basic height-to-weight ratio, whereas IBW considers additional health variables.
Maintaining an Ideal Body Weight
Achieving and maintaining IBW involves:

  • Eating whole, preferably organic, foods.
  • Regular hydration.
  • Daily exercise for at least 15 minutes.
  • Adequate sleep.
  • Adopting sustainable eating patterns like intermittent fasting.


IBW is a guideline, not an absolute. A healthy lifestyle encompasses regular exercise, balanced nutrition, sufficient sleep, and a positive mindset. For personalized IBW calculations, consult a healthcare provider.
