Definition of basal metabolic rate in US English:

basal metabolic rate


  • The rate at which the body uses energy while at rest to keep vital functions going, such as breathing and keeping warm.

    • ‘One of the earliest such tests, the basal metabolic rate, was potentially one of the best, since it measured the effect of thyroid hormone in the body.’
    • ‘In 1956, Hollender reported on 126 patients seen in his otolaryngology practice who had a low basal metabolic rate and were treated with levothyroxine.’
    • ‘These small rodents have exceptionally low water loss rates due to a respiratory countercurrent heat exchanger, highly-concentrating kidneys, and a low basal metabolic rate.’
    • ‘The basal metabolic rate is increased in a few species.’
    • ‘The speed at which this happens is known as metabolic rate; basal metabolic rate is measured when the organism is at rest, and thus shows how efficiently it uses energy.’
    • ‘Advancing age is also associated with a decrease in the basal metabolic rate, as well as changes in the senses of taste and smell.’
    • ‘It tests the body's lean muscle mass, total actual body weight, lean weight, hydration levels, basal metabolic rate, estimated calorie requirement, body mass index and the impedance of the current that travels through one's body.’
    • ‘In general, estrogen leads to an increase in basal metabolic rate as well as increased ambulatory activity and decreased activity of lipoprotein lipase in laboratory animals.’
    • ‘If rapid growth rates reflect the basal metabolic rates of sauropods, then these giant dinosaurs can no longer be regarded as ‘good reptiles.’’
    • ‘Earlier on, I spoke about the possibility of raising your basal metabolic rate, and there is a form of exercise that can help you accomplish this task.’
    • ‘A lot depends upon their size, their activities and their basal metabolic rate.’
    • ‘For every 0.6 [degrees] C increase in core temperature, there is a 10 percent elevation in the basal metabolic rate.’
    • ‘The vitamin-D-deficient calves had increased basal metabolic rates and decreased blood calcium and phosphorus.’
    • ‘That afternoon, I visited the health-services division, where I had my basal metabolic rate charted.’
    • ‘The forager expends 1 unit of energy per time period as a basal metabolic rate, independent of what it is doing.’
    • ‘In adult humans, an estimated 23% of daily basal metabolic rate relates to energy demands of the brain alone.’
    • ‘Physiologically, the body's basal metabolic rate slows down with age and is accompanied by a decrease in lean body tissue and an increase in fat.’
    • ‘Extremely low calorie diets and fasting often result in loss of lean muscle and a resultant decrease in basal metabolic rate, often resulting in health problems and difficulty in maintaining weight loss.’
    • ‘A positive genetic correlation between basal metabolic rate and maximal rate of oxygen consumption is a key assumption of the aerobic capacity model for the evolution of endothermy.’
    • ‘All patients were advised on diet and exercise based on their personal basal metabolic rate.’
