The weight is over!



If you think you have a slow metabolism, you should get it professionally tested.
The technology once reserved for hospitals and universities is now available at Back to Eden Medical Fitness in Tampa, Florida. The Reevue device measures a person's resting metabolic rate with a simple ten minute breath test. Testing your metabolic rates will determine exactly how many calories you may eat to lose or maintain your weight. No more charts, averages, or guesswork. For the first time in years, there is an accurate tool for the thousands of people who are trying to lose weight.
The ReeVue metabolic test revealed I could eat 2400 calories and still lose weight. I really had been starving my body! I bumped up my calories, kept working out, and it was like magic – in one month my weight dropped from 314 lbs to 292 lbs! I felt great and wasn’t hungry any more.- Jack D.

Metabolic Rate Measurements:
Metabolic rate, or metabolism, is the rate at which the body expends energy. This is also referred to as the "caloric burn rate". Knowing metabolic rate is vital for weight loss as well as for determining the proper feeding amounts needed to treat various disease states.
Energy expenditure can be divided into three groups of calories:
1. Resting Calories - Calories that are burned while the body is at rest. These calories are needed just to maintain life. The majority of all calories burned (about 70-80%) are burned at the resting level.
2. Activity Calories - Calories that are burned because of normal daily activities are "Activity Calories". Normal daily activities such as walking, eating, digesting food, typing, etc. are included in activity calories.
3. Exercise Calories - These calories are burned through intentional exercise.
The sum of all of these is the total metabolic rate.

The REEVUE measures the oxygen that the body consumes. Using this measurement it calculates a patient's Resting Energy Expenditure (REE), commonly referred to as a Resting Metabolic Rate (RMR). Physicians can screen for abnormally low metabolic rates, teach energy balance, and pinpoint the precise caloric intake required for weight loss. Indications for use include obesity, as well as obesity related diseases such as diabetes, dysmetabolic syndrome X, hypothyroidism, hyperthyroidism, hypertension, cardiovascular disease, and sleep apnea.

Frequently Asked Questions:

How does the Reevue measure metabolic rate?
Your body consumes a fixed amount of oxygen per calorie burned. The Reevue measures the amount of oxygen in the air you exhale to calculate how much oxygen your body is consuming. Based on your oxygen consumption, the Reevue then figures the exact amount of calories you are burning.

Why should I have my resting metabolic rate tested?

Everyone has a unique metabolic rate. Scientific studies show that even people with similar attributes like age, height, weight, and body composition can have very different metabolic rates. This means that if your metabolic rate is lower than average, you may gain weight even while dieting. Conversely, if your metabolic rate is higher than normal, you may never need to diet to lose weight or you may not be eating enough to lose weight! Metabolic testing reveals how many calories your body burns at rest, giving you the data you need to plan a weight loss, gain, or maintenance plan.

What are the steps of a metabolic rate test?

The Reevue automatically calibrates itself, so there is no need to configure the unit prior to each test. Your body data (age, height, etc.) is entered into the software. You breathe into a disposable mouthpiece to gauge your oxygen consumption. The Reevue determines when you reach your "resting" metabolic rate and it prints a detailed report showing your results and what they mean for you.

Does metabolism change over time?

Metabolism varies from person to person and can change over time. It is determined by many factors including body composition (amount of muscle and fat), weight, age, genetics and gender. Weight loss or a change in body composition can significantly affect your resting metabolic rate (RMR).

How can I increase my metabolic rate?

One of the greatest factors that determines your metabolic rate is genetics, which you obviously cannot change, but the amount of lean body mass one has is also a determining factor. People with more muscle tissue usually have a higher metabolic rate. Other factors that can also increase your metabolic rate are adequate sleep, decreased stress, small frequent meals.

I exercise a lot. Why hasn't my resting metabolic rate increased?
Aerobic, or cardiovascular exercise burns calories during the activity, but does not have a significant effect on increasing your RMR over time. The calories you burn during aerobic exercise will help you balance the calories you eat. Strength training on the other hand burns fewer calories during the exercise, but can add more muscle to your body, which can lead to an increase in resting metabolic rate over time. A combination of aerobic exercise and strength training should be included to improve health.

Can I increase my RMR?
The best and safest method to increase your RMR is to participate in a vigorous strength training program that will add muscle to your body. Muscle burns more calories than fat so having more muscle will lead to an increase in your RMR over time.

I have lost weight. Why is my resting metabolic rate lower?

A decrease in resting metabolic rate during weight loss is normal. Metabolism is influenced by total body mass (your body weight). When you lose weight, your total body mass decreases and it takes less energy for your body to maintain vital functions. In order to minimize this decrease in RMR with weight loss, you can participate in a strength training program. Strength training, if vigorous enough to increase lean muscle mass, can help increase your resting metabolic rate over time because muscle is more metabolically active than fat and burns more calories to maintain, even at rest.

Does losing weight speed up my resting metabolism?

You might be surprised to read the answer is no. Your resting metabolic rate (RMR) actually tends to decrease as you lose weight. This happens because it takes less calories for your body to support a smaller you. This is one of the reasons that it is important to have your RMR re-measured as you shed pounds. Otherwise, you might find yourself plateau-ing too soon and not reaching your goals. One way to counter this trend is to add strength training to your workout plan because lean muscle mass burns more calories than fat. Remember to check with your doctor before starting any exercise program.

Are there any special instructions to follow before getting my RMR measured?

Like many other tests, there are special guidelines to follow prior to your RMR test. These simple rules will help you receive an accurate RMR measurement:

  • You cannot eat for at least 4 hours prior to the test (8-12 hours is preferable).
  • You cannot exercise (cardiovascular or strength training) for at least 4 hours prior to the test (8-12 hours is preferable).
  • You cannot consume caffeine for at least 3 hours prior to the test.
  • You cannot consume nutritional supplements or medications containing ephedra, Ma Huang, or pseudo ephedrine for at least 2 hours prior to the test.
  • You cannot consume nicotine for at least 1 hour before the test.
  • You must be resting for 10-15 minutes before the test is administered. This means you are seated or reclining comfortably and not speaking, reading or watching television.

What’s Your Burn Rate?

If you don't know, then your personal fitness or weight loss plan may not be personal enough.

Until recently, there has not been an easy or economical way to measure metabolism or your burn rate also referred to as RMR (resting metabolic rate). People have relied on predictive equations which are inaccurate for many, particularly those on both ends of the energy balance equation. For example those who participate in strength training exercise programs (high end), or those individuals that have dieted on and off for most of their lives (low end)and have followed the typical "Yo-Yo" effect of cycling weight loss with repeated weight gain.

The Reason:
Lean muscle burns significantly more calories than fat mass and predictive equations can't account for changes in metabolism due to improvements in overall body composition. These predictive equations therefore become quite innaccurate and too low for people on the high end of the energy balance scale, and unfortunately too high for those individuals on the low end of the scale. As you may have heard, the fatal flaw of most low calorie diets is that you end up sacrificing lean muscle. Therefore, during the next round of dieting you have actually negatively effected your body composition (lost lean and gained fat) so your dieting efforts literally ruin you with an even lower RMR due to loss of energy revving muscle.

Oxygen: The univerSal fuel of metabolism

Our bodies use oxygen to metabolize food. So, measuring how much oxygen your body consumes tells you exactly how many calories your body burns at rest each day.

Everyone's metabolism or burn rate is unique to them- a one size fits all approach to weight loss and fitness does not work for most individuals. Take the study outlined in the chart here as an example. You can see that subjects of the same height, weight, age and gender should have had the same burn rate when using the old predictive equation, correct? Well, not exactly. When this group of women were actually measured, their real burn rates were dramatically different. This helps to explain why you can follow the same exercise routine and eat the same foods as your friend, but have dramatically different results. This is also why trying to figure out a weight loss plan based on using powders, potions, diets in a can, as well as points and prepackaged meals based upon outdated "Ideal" height/weight charts will not work in the long run to produce lasting change.

What works?

  • Improving your metabolism or at least doing your best to maintain a high burn rate as you age is the best long term predictor of weight management success.
  • Balancing diet with exercise, both cardiovascular and resistance training, is the most effective way to reach your weight management goals.
  • Resistance training at the correct intensity increases your lean muscle mass and increases your resting metabolic rate.
  • Cardiovascular training burns extra calories and contributes to your total calorie expenditure
  • Get plenty of rest, build in time in your day to have fun, and drink plenty of pure water.
  • Educate yourself and your family about the benefits of healthy eating and and using more whole food nutrition. While supplements may be able to help with some of the nutrients you need they are in no way a replacement for the energy and complex nutrient combinations found in whole foods.

 What doesn't work?

  • Guessing

Stop Guessing....Start Managing

Weight management success is a simple matter of balancing the calories you eat with the calories you burn. The calories you eat can be tracked easily so you know how much you are consuming.

But what about that calories you burn?
As you can see from the energy balance equation chart, this number makes up the biggest part of the "Calories Out" side of the equation. If you are relying on a formula or estimate to give you this number, you might be not too far off from simply guessing. Knowing your real burn rate allows you to establish a calorie budget that works for you. It is also important to know your metabolism can change, sometimes significantly, as you lose weight. Having your metabolism measured throughout your weight management program will help you reach your goals without hitting frustrating plateaus or scarificing valuable lean muscle.
