Active Metabolic Rate (AMR) is defined as the amount of calories burnt by human body in a single day i.e. within a period of 24 hours. This amount is expended through different types of activities that you carry out on a day. Calculating Active Metabolic Rate of the body becomes important for people who want to either loose or gain weight. This is because it helps them keep a check on the calories they burn each day and plan their intake accordingly. It is easy to figure out your AMR. All you need is the basic knowledge of mathematics, plus figures related to your height, weight and age. Read on to learn how to calculate your Active Metabolic Rate.
Calculating AMR Of Your Body
- First, make a note of your weight, height and age, in pounds, inches and years, respectively.
- Before calculating Active Metabolic Rate (AMR), you need to know your Basal Metabolic Rate (BMR), which is the amount of calories burnt by the body to maintain normal body functions. This amount of calories is burnt in a period of 24 hours, even if you are sleeping.
- The formula to calculate BMR for adult men is BMR = 66 + (6.3 x weight in pounds) + (12.9 x height in inches) - (6.8 x age in years).
- The formula to calculate BMR for adult women is BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age in years).
- Now, you will have to calculate Activity Modifier, which is the estimate of how active you are, on a daily basis.
- If you are lightly active, then your activity modifier will be 1.25. If you are habitual of doing exercise almost daily, then your activity modifier will be 1.40. In case if you are a full time construction worker, a professional athlete or highly active person, then the number will be 1.60
- Now that you know the formula to calculate BMR and the Activity Modifier, it is the time to calculate your Active Metabolic Rate (AMR).
- The formula to calculate your Active Metabolic Rate is, AMR = BMR x Activity Modifier.
Benefits of Calculating AMR
AMR calculation helps you to know how many calories have you burnt in a day. This allows you to control your metabolism, just the way you want.In case you are on a diet or trying to loose weight, it becomes important to understand your body metabolism to keep track of your weight. If you eat less than the calories you are burning in a day, you are on the right track. Else, you can consult your dietician or physician regarding your AMR. It has been observed in many cases that even after severe dieting, people fail to lose the desired weight. One of the prominent reasons for this could be a low Active Metabolic Rate. Calculating your AMR will exactly help you adjust your diet accordingly and get better results.
