Heat is a by-product of all metabolic processes and is produced as a result of the metabolism of carbohydrates, protein and fats. The basal metabolic rate is the minimum level of energy required to exist. It is the rate of energy metabolism measured under minimal stress while the animal is fasting.
In humans it is determined after a night of restful sleep and the individual must not have eaten food for at least 12 hoursIn humans the BMR normally averages about 65 to 70 Calories per hour in the average 70 kg man. Although much of BMR is accounted for by essential activities of the CNS, heart, kidneys and other organs, the variations among different individuals are related mainly to differences in amount of skeletal muscle and body size. The BMR per kg of body weight is greater in smaller than in larger mammals. This is necessitated partly by the greater surface/volume ratio of smaller animals. The great surface area provides a larger area for heat loss
