What is Activity Factor?
Activity factor (also called physical activity level or PAL) is a multiplier applied to BMR to calculate TDEE. Values: Sedentary = 1.2; Lightly active (1–3 exercise days/week) = 1.375; Moderately active (3–5 days/week) = 1.55; Very active (6–7 days/week) = 1.725; Extra active (physical job + intense exercise) = 1.9. Most people overestimate their activity level — a desk worker who exercises 3x per week is typically 'lightly active' (1.375), not 'moderately active.'

활동 계수(PAL)는 BMR에 곱해 TDEE를 계산하는 배수입니다. 거의 안 움직임(1.2), 가벼운 활동(1.375), 보통 활동(1.55), 활동적(1.725), 매우 활동적(1.9). 많은 사람들이 자신의 활동 수준을 과대평가합니다.

活動係数（PAL）は、BMRに掛けてTDEEを計算するための乗数です。ほぼ座りっぱなし（1.2）、軽い活動（1.375）、適度に活動的（1.55）、活発（1.725）、非常に活発（1.9）。多くの人が自分の活動レベルを過大評価しています。
