Before you begin on a weight loss program, firstly find out what your current metabolic rate is so you know what you will need to do to increase it. Increasing your metabolism is the best way to help you lose weight so a quick couple of tests will help.
There are two tests to measure your metabolic rate. First is the direct calorimetry which measures energy expended from heat, and the second is indirect calorimetry measuring oxygen used over a period of time. Both are normally used in hospitals with trained technicians.
Everyone has a RMR or Resting Metabolic Rate, and these tests are designed to gauge the results for people. You cannot eat before the test for at least 1 to 2 hours, no exercising can be done beforehand and no coffee or other stimulants can be taken.
Once you are sitting down and relaxed you will be given a breathing apparatus to put on. You simply sit there 15 minutes usually and afterwards a report will be available.
You will need to return to do another test after a while simply because once you start your diet your metabolic rate will change. Taking this test can be very useful if you are looking to lose weight. It will show you what you need to do in order to increase your metabolic rate which will ultimately be what helps you to lose and shed those pounds forever.
