PAL Calculator (Physical Activity Level)
TDEE ÷ BMR — the dimensionless activity index FAO/WHO uses to classify lifestyles, computed from your real numbers.
PAL strips body size out of the activity question — a 1.55 means the same lifestyle for a 50 kg or a 100 kg person. Doubly-labelled-water studies put the sustainable human ceiling near 2.5 (Tour de France riders briefly touch 4–5). If your claimed PAL exceeds 2.2 without daily hard training, the activity guess is optimistic.
