Similarly, if you consume food then you need enough energy to break it down. You even need energy to keep your heart beating and pumping blood throughout your body. So if were to measure the metabolic rate of the body and get the answer of does your metabolism affect your weight, then we would actually be taking a measure of the energy that is required by the body while it is in a mode of rest. For this purpose, the rate has been called the “Resting Metabolic Rate” and there is a formula that helps in the measurement of the RMR and is based on the weight, age and height of a person.
This formula of RMR is just simply an approximate as there is no allowance for someone who is 6 feet tall with a perfectly chiseled body or another person who weighs the same amount and with the same height, but with a big beer stomach and low muscle tone. This formula just works as a guide on the number of calories.
The formula is: Calories burnt in the day – calories consumed
This would either give a positive or a negative answer depending on whether you have consumed more calories of burnt more.
Your question can be understood through this formula as it gives an indication of the number of calories that you use every day and if you add all this, then you get an approximate about the number of calories you are actually burning through your daily activity. This would give you the calories burnt part of the equation and the next thing that you have to do is to keep a check on the amount of calories that you eat.
If you consume less calories than you burn than it is pretty obvious that the difference would indicate a shortfall in the amount of energy and most people would assume that the body would make up for this shortfall by burning more calories. This is shown in the weight that you are able to lose and this is how your metabolism affects your weight.
