Ideal Weight vs Healthy Range: Which Should You Aim For?
There's no single 'perfect' weight. Classic formulas give a single number, while the healthy range gives a band — and the band is usually the kinder, more realistic target.
Let's compare both approaches so you can set a goal you can actually live with.
The formula
Formulas like Devine estimate ideal weight from height and sex; the healthy range spans BMI 18.5–24.9.
Why a range is better
A range respects natural variation in frame size and muscle. Aiming for a band reduces pressure and is easier to maintain.
Set a kind target
Pick a point in your healthy range that fits your lifestyle, then focus on habits rather than the scale alone.

Frequently asked questions
Which formula is best?
All are approximations; treat the BMI healthy range as a target band rather than chasing one exact number.
Does frame size matter?
Yes — larger frames sit comfortably toward the top of the healthy range.
