3500 kcal ÷ 3,500 kcal/lb = 1.0000 lbs

Formula

Pounds of fat = 3500 ÷ 3,500 = 1.0000

Step-by-Step Derivation

  1. 1 lb of adipose tissue ≈ 3,500 kcal (Wishnofsky, 1958)
  2. 3500 kcal ÷ 3,500 kcal/lb = 1.0000 lb
  3. Dimension check: [Energy] ÷ [Energy/Mass] = [Mass] ✅

What This Means

The origin of the 3,500 kcal per pound rule, from Max Wishnofsky's 1958 paper. It remains a useful heuristic, though modern research shows metabolic adaptation reduces its accuracy over time.
