Understanding BMR and the factors affecting BMR

BMR or basal metabolic rate is the ground rule for all types of fitness goals that people want to achieve. Basal Metabolic Rate is the number of calories required to keep your body functioning at rest. BMR is also known as your body’s metabolism; therefore, any increase to your metabolic weight, such as exercise, will increase your BMR.

Metabolism comprises of the functions that the body requires to function. BMR is expressed in the form of calories required by the body. The higher the BMR the lower the probability of body fat being accumulated. Breathing, blood circulation, controlling body temperature, cell growth, brain function etc are all metabolic activities. The basal metabolic rate accounts or for almost 60-70 % of the entire caloric expenditure. Your BMR does not include the calories your burn from daily activities or exercise but they help amplify the BMR at large.

Some of the factors that affect BMR are:

1. Body size: A persons height, weight etc influence the BMR of that person on a large scale.

2. Body Type: The somatotypes Mesomorph, Ectomorph, Endomorph, are all defined by a particular BMR that gives the body a particular shape.

3. Age: With increasing age the lean muscle mass in the body keeps reducing resulting in a decrease in BMR by every passing year.

4. Hormones: Hormonal function in the body plays a vital role in defining the BMR of the body. Better hormonal function better the BMR.

5. Gender: Your gender also affects the BMR of your body. BMR of males is generally higher than that of females as males have larger capacity to build muscle than that of females while females have more fat stores than men.
