Physical Activity Level (PAL) is a measure that indicates the amount of physical activity a person engages in during a specific period. It is often calculated by multiplying the Basal Metabolic Rate (BMR) by an activity factor that reflects daily activities, exercise, and overall lifestyle. PAL helps in assessing energy expenditure and can guide individuals in managing their weight and health. PAL is categorized into different levels, such as sedentary, lightly active, moderately active, and very active. Each category corresponds to a specific range of daily energy expenditure. Understanding your PAL can assist in making informed decisions about exercise, diet, and overall health.
