Basal Metabolic Rate is the number of calories your body needs to maintain basic functions at rest.

Knowing your BMR helps you create effective nutrition plans for weight loss, maintenance, or gain.

Your total calorie needs depend on your activity level, calculated by multiplying your BMR by an activity factor.

Activity Level	Description	Multiplier
Sedentary	Little or no exercise	BMR × 1.2
Lightly active	Light exercise 1-3 days/week	BMR × 1.375
Moderately active	Moderate exercise 3-5 days/week	BMR × 1.55
Very active	Hard exercise 6-7 days/week	BMR × 1.725
Extra active	Very hard exercise & physical job	BMR × 1.9
