Physical activity level (PAL) is determined based on United States Department of Agriculture (USDA) "Physical Activity Level" (https://fnic.nal.usda.gov/sites/fnic.nal.usda.gov/files/uploads/107-264.pdf).

Baseline activity is: the light-intensity activities of daily life, such as standing, walking slowly, and lifting lightweight objects.

Sedentary
No activity beyond baseline activities of daily living

Low activity
Activity beyond baseline but fewer than 150 minutes of moderate-intensity physical activity a week

Activity
150 minutes to 300 minutes of moderate-intensity activity a week

Very active
More than the equivalent of 300 minutes of moderate-intensity physical activity a week
