What is basal metabolic rate How does your basal metabolic rate affect your calorie needs?

Basal metabolic rate (BMR) is the number of calories your body requires to maintain basic physiological functions at rest, such as breathing, circulation, and cell production. It accounts for the majority of your daily energy expenditure. Your BMR affects your calorie needs by determining the minimum amount of energy required for your body to function, influencing how many calories you should consume based on your activity level and overall goals, such as weight loss, maintenance, or gain. A higher BMR means you need more calories, while a lower BMR indicates a lower caloric requirement.
