How to measure you metabolism
This time were going to talk about getting your metabolism measured. Getting your metabolism measured could be one of the single most important aspects to getting started with a hypothyroidism diet. Reason being, if you’re trying to attain a goal, such as hypothyroid weight loss, it’s important to know how your body is consuming the calories that you’re taking in during the day. This is one way to make sure that you’re taking in the correct amount of calories, not too much or too little.
How metabolism measured?
Your metabolism can be measured a couple of different ways. The first method is called direct calorimetry. This method measures the energy expended in the form of heat. This test is not practical for our purposes. The other method is called “indirect calorimetry”, it measures the amount of oxygen consumed over a period of time. Traditionally this was only available in hospitals and research facilities due to the cost of the apparatus used and the need for trained technicians to run it. But, nowadays it’s possible to get the test done almost anywhere the machines are available. I know of some dietitians that now have these machines to aid them in properly gauging a client’s daily caloric needs when creating a diet for them.
What are the needed preparations for the test?
The aim of the test is to gauge the RMR or the Resting Metabolic Rate of an individual. Therefore, he or she needs to avoid eating anything for a while before the test, avoid exercising on the day of your test and avoid the use of stimulants such as caffeine on the day of the test. I had the procedure done and I was asked to fast for 4 hours prior to the test.
What happens during the test?
You will relax in a seated position. A mask or mouthpiece would be used and you have to breathe through there until the test concludes, usually ten to fifteen minutes. If a mouthpiece is used a clip will typically be place on your nose to reduce the infiltration of any oxygen that could ruin the test. If this is bothersome to you ask if they can get mask for you to use.
The only problem I had was when I swallowed the saliva that built up in my mouth during the test my ears would block up. After the test completes a report will either be printed out by the machine or displayed on its screen. The important part is that the dietitian will use the results in order to come up with the best plan for your hypothyroidism diet.
The bottom line is once you have a starting place or baseline to go by and a goal; your chances of reaching your desired weight will dramatically increase.
