5 Reasons Why You Don't Need An RMR Test

A metabolism test measures the rate at which your body burns calories, also known as your Resting Metabolic Rate (RMR). This information can be used to tailor a diet and exercise plan that is specifically designed for your body's needs. However, do you really need it?

Even though it's my job to convince you to get an RMR test, it's also my job to help find the best way for you to get in shape. So no, you don't need an RMR test.

Why not?

1. You can use a calculator

The most important factor in achieving any goal is to ensure you are eating the right amount of calories for your desired outcome. You can still calculate how many calories you need based on your activity level, height, weight, and age using a calculator. Although this may not give you a perfect result, it will give you a starting point. With a little trial and error, you can then find the perfect combination of diet and exercise that will help to boost your metabolism and improve your overall health.

2. A metabolism test is expensive

A metabolism tests isn't cheap. At Box we charge £99 and is understandably, something that not everyone can afford.

3. The results can vary

An RMR test can be affected by factors such as stress, illness and temperature, making it difficult to get a foolproof reading. This is the reason that if you do choose to have an RMR test, don't do it if you're poorly, ensure that you don't eat for at least 4hrs before and refrain from partaking in hard exercise for 24hrs prior to you test.

4. You might not get the results you were hoping for

If you choose to do a metabolism test, you'll likely get two outcomes. The first is that your RMR is normal and it's what you're eating that is the issue, not your metabolism! The second is that your metabolism is slower than normal and weight loss will now be more difficult. So no good news :(

5. Your metabolism is fluid

An RMR test will only give you your metabolic rate at that particular time point. Although it shouldn't change much, weight loss will cause a reduction in your RMR meaning that you will still have to adapt your nutrition whilst dieting.

What can you do if you're struggling to lose weight?

Losing weight is difficult for many people, and there are a variety of reasons why someone might struggle to shed pounds. Genetics, metabolism, and activity level all play a role in determining how many calories your body burns at rest. If you're trying to lose weight, it's important to consult with a dietician or nutritionist to create a diet and exercise plan that's realistic for you. Depending on your RMR and activity level, you may need to consume fewer calories than someone with a faster metabolism in order to see results. A professional can help you determine how many calories you should be eating and the types of exercise that will help you reach your weight loss goals. By creating a plan that's tailored to your individual needs, you'll be more likely to see results and be successful in reaching your desired weight.
