A common pathological cause for a high BMR is fever, since a rise in body temperature increases the rate of cellular metabolic reactions. It is estimated that for every degree Fahrenheit of rise in body temperature, the BMR increases by 7 percent.
Why does fever increase BMR?
Fever is part of the immune system’s attempt to beat the bugs. It raises body temperature, which increases metabolism and results in more calories burned; for each degree of temperature rise, the energy demand increases further. So taking in calories becomes important.
Is BMR reduced by fever?
The resulting fever increases basal metabolic rate (BMR) by 13% for each 1 degree C (DUBOIS, 1937).
What increases basal metabolic rate?
Environmental changes such as increased heat or cold forces the body to work harder to maintain its normal temperature and increases BMR. 9. Drugs. Caffeine and nicotine can increase your BMR whilst medications such as antidepressants and steroids increase weight gain regardless of what you eat.
What is the effect of body temperature on BMR?
Second, increases in body temperature, denoted by ΔT(M), have an exponential effect on the metabolic rate. These increases are best characterized using muscle temperatures because muscles consume more than 90% of oxygen at V ˙ O 2 max (Weibel et al. 2004).
Is a high or low BMR good?

What does a low BMR indicate?

The Metabolic age is calculated by comparing your Basal Metabolic Rate to the average BMR of your chronological age group.
