⚖️ What is Ideal Body Weight?
Ideal body weight (IBW) is a range of weights associated with the lowest health risks for a given height and gender. It's important to note that ideal weight is a range, not a single number.

❓ Frequently Asked Questions
Which ideal weight formula is most accurate?
The Devine formula is most commonly used in medical settings. However, the healthy BMI range (18.5-24.9) is often preferred for general health assessment.
Why do different formulas give different results?
Each formula was developed at different times using different populations. Showing multiple formulas gives you a realistic weight range.
What if I'm muscular?
Ideal weight formulas don't account for muscle mass. Body fat percentage is a better health indicator for athletes.
How does age affect ideal weight?
As we age, muscle mass naturally decreases. A slightly higher BMI (up to 27) may be acceptable for older adults.
