What is Basal Metabolic Rate (BMR)?

Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions while at rest, such as breathing, digestion, and maintaining body temperature. It is an important measure to understand how many calories your body burns without any physical activity.

Knowing your BMR helps you tailor your diet and fitness routine. If you want to lose weight, you need to consume fewer calories than your body needs (i.e., less than your BMR), while if you want to gain weight, you need to consume more calories than your body burns.
