  Basal metabolic rate: - Atkinspedia
The Basal metabolic rate (BMR) is the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state (meaning that the digestive system is inactive, which requires about twelve hours of fasting in humans).
BMR and RMR are measured by gas analysis through either direct or indirect calorimetry, though a rough estimation can be acquired through an equation using age, sex, height, and weight.
Studies of energy metabolism using both methods provide convincing evidence for the validity of the respiratory quotient (R.Q.), which measures the inherent composition and utilization of carbohydrates, fats and proteins as they are converted to energy substrate units that can be converted by the body to energy.

The minimum rate of energy expenditure at any given time in an animal is not always the same and depends upon such things as the previous nutritional state, absence of disease or infection, the body temperature, the phase of the menstrual cycle in the female, and the degree of wakefulness.

The purpose of the present study was to investigate the net change in the basal metabolic rate (BMR) of individuals actively engaging in a combination of yoga practices (asana or yogic postures, meditation and pranayama or breathing exercises) for a minimum period of six months, at a residential yoga education and research center at Bangalore.
The measured BMR of individuals practicing yoga through a combination of practices was compared with that of control subjects who did not practice yoga but led similar lifestyles.
In addition, the mean BMR of the yoga group was significantly lower than their predicted values, while the mean BMR of non-yoga group was comparable with their predicted values derived from 1985 WHO/FAO/UNU predictive equations.

 Basal Metabolic Rate: Calories Burned
Basal Metabolic Rate is the number of calories you need daily for your body to carry out basic involuntary functions, like breathing and cell-repair.
Put simply, basal metabolic rate is an estimate of how many calories you would burn if you were to lie in bed asleep for 24 hours, with measurement beginning 12 hours after your last meal to ensure that your digestive system was inactive and not burning calories digesting food.
This basic rate of calories burned is the result of many factors including, gender, age, height, muscle-fat ratio, fitness, hormones and so on.
