What is Basal Metabolic Rate? by Michael Cummins, Sat 23 Dec '17

What is Basal Metabolic Rate?

"Basal metabolic rate (BMR) is the minimal rate of energy expenditure per unit time by endothermic animals at rest."

"Metabolism comprises the processes that the body needs to function. Basal metabolic rate is the amount of energy expressed in calories that a person needs to keep the body functioning at rest."

"The basal metabolic rate accounts for about 60 to 75% of the daily calorie expenditure by individuals."

"BMR generally decreases with age and with the decrease in lean body mass (as may happen with aging). Increasing muscle mass has the effect of increasing BMR."

"Basal metabolism is usually by far the largest component of total caloric expenditure."

"A decrease in food intake will typically lower the metabolic rate as the body tries to conserve energy."
