Evaluation of WorkoutOptimizer™ Results

How does the WorkoutOptimizer™ work?

Researchers have known that the body’s fuels (sugars, proteins and fats) contain different isotope fingerprints. An isotope fingerprint just refers to the amount of heavy to light atoms. When we digest foods and convert to energy, we release the carbon atoms in the breath as carbon dioxide. We measure the isotope fingerprint of carbon dioxide with a highly accurate scientific instrument called an isotope ratio mass spectrometer. We can measure the heavy to light carbon atom ratio to 4 decimal places.

The ratio of heavy to light carbon atoms can be used to estimate carbohydrate (sugars) and fat oxidation rates during exercise. Originally published in 1992 by Romijn et al. (Am. J. Physiology 263:E64-E71, 1992), the technique has been compared to the gold standard of measuring oxidation rates, indirect calorimetry. We have utilized this technique and combined it with our own research work to derive a simple way to determine the amount of carbohydrate and fat calories burned based on the isotope finger print in the breath.

Interpretation of  WorkoutOptimizer™

Each breath sample is analyzed for your carbon dioxide isotope fingerprint. Our reports show the total calories burned during your exercise, carbohydrate and fat calories burned:

The following definitions and descriptions are meant to improve your understanding of your workout results and to help you optimize the benefits of your personal workout profile:

Your Body Mass Index: Body Mass Index (BMI) is a number calculated from your weight and height. BMI is a fairly reliable indicator of body fatness. For more complete information from the United States Centers for Disease Control and Prevention click here: http://www.cdc.gov/healthyweight/assessing/bmi/adult_bmi/index.html

Your Resting Energy Expenditure: This is the number of calories that you burn every day while at rest. Things like breathing, blinking and other involuntary movements are included. It does not include normal, everyday activities or any exercise.

Your Total Daily Energy Expenditure: This is an estimate of the number of calories that you burn every day going about normal activities. It includes your Resting Energy Expenditure (see above) PLUS normal activities such as eating, working and other light activities. It DOES NOT include any calories burned during exercise.

Recommended Body Weight: Based on the information you provided on your information sheet, this is the body weight that will bring you into the normal BMI range (20-25).

Recommended Weight Loss: This is simply your current weight minus your Recommended Body Weight.

Recommended Daily Intake of Calories: Based on your Total Daily Energy Expenditure and your Recommended Weight Loss this is the number of calories you should eat (per day) in order to lose an average of 1 pound per week.

Total Calories Burned During Exercise: In this graphic, we have given you three (3) pieces of information:

1. Resting: This is the number of calories you would have burned during the time you exercised had you simply been resting.
2. Your Result: This is the number of calories that you ACTUALLY burned during the time that you were exercising.
3. Optimal Result: This is the number of calories we would suggest you burn during this exercise period in order to optimize your workout. Check out Your Recommendations to learn the best strategies to achieve this optimal result.

Your Personal Fat Burn during your Exercise: In this graphic, we have shown the number of fat and carbohydrate (sugar) calories that your body burned during your exercise. For comparison, we have also shown the Optimal Burn for each for the exercise period. Burning calories is always good but burning fat calories is the best for both weight loss and creating maximal lean body mass.
