What is BMR
The Basal Metabolic Rate, or BMR, is an estimate of how many calories you would burn if you were to do nothing but rest for 24 hours. It’s the amount of energy you need while resting in a temperature environment during the post-absorptive state, or when your digestive system is inactive. In this state your energy will be used only to maintain your vital organs such as the heart, kidneys, lungs, intestines, liver, muscles or skin.
An accurate BMR measurement requires that the adult’s sympathetic nervous system not be stimulated, a condition which requires complete rest.
If you have noticed that every year, it becomes harder to eat whatever you want and stay slim, that it’s because your BMR decreases with age.
Your BMR does not include the calories you burn from normal daily activities or exercise.

Why your BMR is important
It’s very important to understand your BMR (Basal Metabolic Rate) if you are looking to lose weight, maintain your current weight, or gain weight (muscle mass).
The body uses calories as a source of energy for daily activities. Counting calories is a popular tool for weight management and establishing a healthy diet. The calories burned by an average person are based on their basal metabolic rate and their activity level. BMR calculations are being used by the public to formulate weight loss plans that proponents claim can be tailored to the individual needs of the individual.
Since BMR is a calculation of how much energy it takes to maintain life, you can calculate how many calories you need to maintain your weight, or if you need to gain or lose weight.
However, these numbers are also dependent upon how active you are. Since exercising burns calories, if you are very active, you will need more calories versus someone who is not as active.
You should never eat less calories per day than your BMR, because your are depriving your body of it’s most basic supply of energy to optimally perform the most vital functions. Never a good idea.
What affects my BMR?
Anything that results in an increase to your metabolic rate will increase your BMR. This includes stress, fear, illnesses and exercise or activity level.
Your BMR is relative to Height, Weight, Age, and Gender (men need more calories than women), but can be affected by other factos such as:
|Age||BMR decreases as age increases.|
|Gender||Males have a higher BMR than females.|
|Pregnancy||BMR increases during pregnancy and lactation.|
|Increased intake of foods||Eating larges amounts of food requires more energy to process more material.|
|Environmental conditions||Extreme temperatures require more energy to maintain body temperature.|
|Stress||Increased heart rate or blood pressure need more energy.|
|Sleep time||The more you sleep, the less energy your body needs.|
Other factors: fasting, malnutrition, or increase secretion of certain hormones (testosterone, insulin).
