When you are preparing for a resting metabolic rate (RMR) test, you should keep the following in mind: • Fasting - You shouldn’t eat for 4 to 5 hours before your RMR test. During this period, you should also avoid coffee and other caffeinated products to ensure the accuracy of the test. • Avoid smoking or drinking - You should avoid smoking or drinking alcohol before your test, as doing so can impact your results. • Do not exercise - Before your test, you should stop exercising about 5 hours before. In addition, high-intensity weight training should be stopped 12 hours before your RMR test. • Hydrate well - Dehydration can affect the accuracy of the results, so aim to drink enough water in the hours leading up to the test without overhydrating, which can skew results as well. • Wear comfortable clothing - We recommend that you wear comfortable and loose-fitting clothing for your RMR test.
