Question 1

What are the ideal weight formulas?

Accepted Answer

Four widely used formulas exist: Devine (1974), Robinson (1983), Miller (1983), and Hamwi (1964). Each uses height and gender to estimate ideal body weight, with slight variations in calculations.

Question 2

Why do different formulas give different results?

Accepted Answer

Each formula was derived from different study populations and methodologies. The variation reflects different perspectives on optimal weight. Using multiple formulas gives a reasonable range rather than a single number.

Question 3

Is ideal weight the same as healthy weight?

Accepted Answer

Not exactly. Ideal weight formulas provide estimates based on height and gender, but healthy weight also depends on body composition, muscle mass, bone density, and individual health factors.
