The basal metabolic rate counts the minimum number of calories necessary for a person to burn in order to sustain their basic life functions during a resting period of 24 hours. Usually it is an estimate. Why? We are more active on some days than on others. We eat more food on some days than on others. We eat healthier on some days than on others.
So, what is RMR? RMR stands for Resting Metabolic Rate. Some folks use BMR and RMR interchangeably, but there’s a slight difference between the two. RMR estimates the number of calories a person burns during a period of inactivity. One is not required to fast or rest for an extended period like that of BMR (in a controlled clinical setting) in order to get this estimate. Due to the less strict testing conditions for measuring the RMR, it may be slightly less accurate than the BMR. Plus, I find it really difficult to find 24 hours where I am completely at rest, recent surgeries and hospitalizations not included.
The amount of carbon dioxide and oxygen exhaled and inhaled by a person is analyzed during BMR calculations. Fitness experts, clinicians, or scientists also consider height, weight, age, and sex. Calculating BMR by oneself is quite difficult. According to the U.S. Dietary Guidelines for 2015-2020, adult women require 1,600 to 2,400 calories per day, and adult men require 2,000 to 3,000 calories per day. These guidelines also indicate that BMR decreases with the increasing age of a person. A person’s regular activity level is crucial in determining BMR. The higher one's activity level, the higher the BMR. The higher the BMR, the more calories one can consume without gaining weight. That is why being active one's whole life is important.
We can be a partner always with our body by increasing lean muscle mass and decreasing weight from fat. We can do these things by eating a balanced diet, performing regular cardiovascular exercise, and practicing resistance training. It does not have to be a battle. Walking up hill combines resistance training and cardiovascular health. Stretching in the many types of stretching classes expands the fascia and muscles within, and holding the stretches allows resistance training to come into play. A simple plank works the front and back body, arms, chest, core, legs, glutes, and back. Asking someone to be a partner in your efforts makes life with movement more fun, and adds a layer of accountability.
