When we have your TDEE we can then determine how many calories you should eat daily to reach your body composition and performance goals. Once you know your actual RMR you can then add in your activity level and figure out your TDEE. These formulas have been used for years for an estimated metabolism, sometimes they are very close sometimes they vary 50-100 calories but the only way to find out your actual Resting Metabolic Rate is to use a direct or indirect calorimeter. But lean body mass does play a factor in your metabolism. It can be off for regular people as well. Often times with people who are active and have a muscle the formulas can be off upwards of 400-500 calories. Some people prefer to use one over the other, it’s a personal preference but at the end of the day they are formulas not YOUR EXACT metabolism which means there is room for error. The most commonly used are the Harris Benedict Equation, The Cunningham Formula, The Mifflin St. They combine your age, height, weight and sometimes body fat mass to determine your RMR. There are a few formulas that have been created by scientists over the years which we use today to determine your RMR. If you consume less you will lose weight and more you will gain weight.ĮAT (Exercise Activity Thermogenesis): The calories you use while exercising.
If you consume the same calories as your TDEE you will not gain or lose weight. TDEE (Total Daily Energy Expenditure): The sum of your RMR+TEF+NEAT which determines your daily caloric expenditure. This includes walking to work, cleaning the house, shopping, fidgeting, playing with your kids, showering, etc. NEAT (Non Exercise Activity Thermogenesis): Energy expended for everything we do that is not sleeping, eating or exercise. Protein is the most thermogenic macronutrient which means it takes more energy to digest protein than fat or carbohydrates. TEF (Thermic Effect of Food) : Energy used to digest and use the food you eat. It’s usually about 75% of your total metabolism. It’s your metabolism when you wake up in the AM (hence resting) before any you do any activities such as eat.
RMR (resting metabolic rate) : Energy used to do basic bodily functions and have your organs work. But for you it’s the rate at which you are burning calories (using energy). It’s a really complicated chemical process which could take years to fully understand. Technically it’s the chemical process which occurs in your cells to create and break down energy. In this post I will explainįor the sake of simplicity -Metabolism is the rate at which your body burns calories. This information has historically been estimated, which may not be accurate for everyone, and is often the cause of frustrating weight plateaus.I often get this question when I tell people that I offer metabolic testing from an FDA approved device called the BodyGem®. RMR comprises a majority of the total calories an individual burns each day, so knowing your Metabolic Fingerprint™ is vital to success.

The BodyGem® metabolic measurement device by HealtheTech is a handheld and portable unit that measures resting metabolic rate (RMR), the number of calories your body burns at rest each day.īodyGem measures your unique Metabolic Fingerprint™ – the missing link to personalizing weight, nutrition and overall fitness programs for optimal results.Ī successful weight and nutrition management program is just a matter of having the right information and balancing calories “in” with calories “out”. The device can be a great aid in a weight management process (everyone’s favorite past time, even if it is only in the head!):

CBS4 TV from Boston, recently featured a story about the Body Gem resting metabolic rate analyzer from HealtheTech, Inc., a company out of Golden, Colorado.
