BMR Calculator
The Basal Metabolic Rate (BMR) Calculator estimates your basal metabolic rate—the amount of energy expended while at rest in a neutrally temperate environment, and in a post-absorptive state (meaning that the digestive system is inactive, which requires about 12 hours of fasting).
About Basal Metabolic Rate
The basal metabolic rate (BMR) is the amount of energy needed while resting in a temperate environment when the digestive system is inactive. It is the equivalent of figuring out how much gas an individual expends during a day. BMR decreases with age and with the loss of lean body mass. Increasing muscle mass can help increase BMR, which is why exercise and strength training are important for weight management.
