Ideal weight formulas & real health — education
Devine and Robinson formulas were developed for clinical drug dosing and reference tables—not as beauty ideals. Healthy weight ranges on charts cannot capture muscle, bone structure, ethnicity-specific risk, or personal goals.
Reference snapshot
Formulas vs. BMI
Ideal-weight equations and BMI categories often overlap but are not identical—both are approximations.
NCBI Bookshelf and pharmacology references discuss ideal body weight in dosing context; BMI is the more common screening metric today.
How to use these numbers
If your “ideal” result differs a lot from where you feel strong and your labs are good, trust the bigger clinical picture. Some people healthfully live above chart midpoints; others need support below them for metabolic reasons.
Beyond the scale
- Waist circumference and blood pressure, lipids, and glucose tell more about cardiometabolic risk than one formula output.
- Strength, mobility, and mental health are legitimate components of “healthy weight” conversations.
When charts mislead
Bodybuilders, rugby players, and rowers may exceed formula ranges with low health risk. Frail older adults may sit in “normal” BMI with low muscle—sarcopenia discussions matter.
