Metabolic Rate Explained - BMR vs. RMR

Understanding your metabolic rate -

So, there is much more flexibility than many assume. First, you just learned that your metabolism is more than one thing. It is a collection of many different aspects of your body and its functions. Also, you learned that you have some control over at least parts of it.

Let me explain these two ideas with a few examples. In one of the more interesting studies of the s, scientists tested to see what happens to people when they increase or decrease their calories 1.

Primarily, they increase their non-exercise physical activity; they started moving around more. Their resting metabolic rate also increased very slightly, with some of that coming from an increased thermic effect of food, but some of it also comes from having an increased body mass.

The same thing happened when they decreased their calories , but in the opposite direction. When people decreased their calorie intake, their physical activity decreased, as did their thermic effect of food and their resting metabolism from reduced body mass.

In short, their metabolisms adapted to the scenario their body was being exposed to. Most studies that examine resting metabolic rate find that it does not predict weight gain or weight loss at all.

Outside of your resting metabolism, your non-exercise activity thermogenesis NEAT is the most essential aspect of your metabolism.

Furthermore, two studies that followed the contestants of the weight loss television show The Biggest Loser found that their physical activity, including their NEAT, was the most significant predictor of who gained back the weight they lost from the show and who did not 3 , 4.

There is a meme that exists that people can have a broken metabolism that causes them to gain weight. Sure, your metabolism can decrease when you lose weight by carrying less body weight, moving around less, and having a lower thermic effect of food.

Your metabolism can also decrease if you have significant hormonal issues, such as hypothyroidism. There are many ways to measure resting metabolic rate , some more accurate than others. We can measure things like metabolic equivalents, which relies on metabolic rates, but the accuracy is still suspect.

Your food intake and your NEAT are far more critical for weight loss efforts than your resting metabolic rate.

We often think about our metabolism as one thing. In reality, it is the full collection of all the energy-producing and energy-consuming processes that occur in our body. It is made up of our resting metabolism, the energy it takes to process our food, and our physical activity.

Your metabolism adapts to calorie increases and decreases, with a large part of the adaptation coming from changes in physical activity.
