No matter what you do during the day, you are burning calories. As we mentioned in our last post, different activities burn different amounts of calories at a different rate. So, what is your average rate of just naturally burning calories? That’s where the Resting Metabolic Rate comes in, also known as RMR.

Here’s how to calculate your RMR:

RMR = [Lean Body Mass in lbs] / 2.205 X 30.4

So, find out what your lean body mass is (in other words, check your body fat percentage and calculate you lean body mass), divide that by 2.205, and then multiply that by 30.4. That will give you a good idea of what your RMR is, and from that you can get a good idea of how many calories you should be.

So how do you use this information? Well, if you are trying to lose weight, then you need to eat less than your RMR. If you are trying to gain weight, then you should be eating more calories than your RMR.

One thing to keep in mind with this is that the RMR doesn’t necessarily take into account extra calories burned by doing exercise. The concept is mainly based on if you have more lean body mass (more muscle), your body will work more efficiently and naturally burn more calories rather than a body that has less muscle. RMR is only to be used as a guide to help you make some plans for your lifetime fitness goals.
