What is BMR?
BMR or basal metabolic rate is the total amount of calorie your body needs to run its primary functions, including breathing and keeping your heart beating. BMR does not take into account any physical activity. So, since the body needs energy to also do simple activities like walking and doing your daily work, the total calorie you need to consume everyday would be higher than your BMR.
