Metab­o­lism FAQ's

Metab­o­lism FAQ's

Although the word "metabolism" is familiar to most health and fitness professionals, how to test it and what it means often eludes most people who believe they have a slow metabolism.  Here are some answers to Frequently Asked Questions (FAQ's) that usually enter our discussions with new clients at Genesis personal Fitness.

How does the test work?

At Genesis Personal Fitness, we use the KORR Medical Metabolic Analyzer which utilizes the same technology as ICU metabolic testing. Because every calorie a person consumes requires a fixed amount of oxygen to be converted to energy, our KORR Analyzer measures the oxygen you consume to calculate the  calories you burn. All of the air exhaled by you during the test must be collected to measure oxygen consumption. Two one-way valves in the KORR MetaBreather ensure that only fresh air is inhaled and all exhaled gas passes through the hose and into the air flow sensors of the Metabolic Analyzer. A nose-clip ensures that all exhaled air is analyzed.  The test is simple and painless... you just sit back, relax, and just breathe!

Does your Metabolism decline with age?

A person's Resting Metabolic Rate (RMR) naturally declines slightly as an individual ages. The cause is not clear. One reason may be due in part to a slowed metabolic rate of individual organs, such as the brain, liver, heart, and kidneys. These organs alone account for 60% of RMR in adults, and all but the heart decreases in mass with advancing age. Another proven cause is the decline in physical activity such a regular strengthening exercise that unfortunately leads to a decrease in lean mass and bone mineral density.  Yet with a proper program of safe, effective strength training exercise, you can easily halt the further decline of your metabolism and avoid faster weight gain as you get older. 

Does a history of unsuccessful dieting affect your Metabolism?

While each person reacts differently to repeat dieting, studies show that this behavior causes a surprising decline in your ability to burn calories at a healthy rate even if your weight loss efforts are successful.  This is the reason why so many people who lose weight always seem to regain it and more, which ultimately leads to frustration and predictable weight gain as time goes on.  This is why it is recommended that you have your metabolism tested at least every 1-2 years so you can avoid the dreaded weight gain "creep" that tends to surprise most people.

Isn't your metab­o­lism genet­i­cally pro­grammed and can't be changed?
The truth it... as with many genetic traits, your body may have a pref­er­ence or coding for certain factors and behav­iors that influence your metabolism. But there is a lot of "wig­gle room" in the matter. Just how much these factors and behaviors affect your metabolism is deter­mined by the choices you make for your body.  By tak­ing care of your metabolism—proper regular exer­cise, healthy diet, good lifestyle habits—you can train your body to deliver its best pos­si­ble per­for­mance. Lack of exer­cise, poor diet, and gen­eral lack of atten­tion to your health, on the other hand, can thwart even the best nat­ural metabolism.

What is the effect of strength training on your Metabolism?

Regular, consistent strength training (25 minutes per session, 3 times per week) can result in a healthy increase in your Resting Metabolic Rate (RMR). This means that your body can burn more stored fat calories at rest simply by keeping your muscles strong and healthy.  In fact, studies indicate that by restoring optimum function and strength to most of the bigger muscles of your body, you can burn an extra 200-300 stored fat calories per day, or in other words, prevent you from gaining over 20 pounds per year.  Think of regular strength training as your built-in weight manager.  At Genesis Personal Fitness, we specialize in a very specific method of strength training that is safe and highly effective, designed to meet your individual metabolism's needs.

What is the effect of cardiovascular/aerobic exercise on your Metabolism?

Although many studies have been done regarding this question, there is not a simple answer to this question due to the many variables involved: the type, duration, frequency and intensity of exercise, degree of energy deficit, total daily calorie intake, and distribution of calories between fats, proteins, and carbohydrates. A conservative summary of the existing research would be that your Resting Metabolic Rate does decrease in response to doing too much or the wrong type of cardio/aerobic exercise.  This is why at Genesis Personal Fitness, we recommend that you consider having an Exercise Metabolic Test (VO2 Max) to determine the precise type of cardio/aerobic exercise you should perform based on your metabolism's unique response while exercising.
