For example if you have two groups, and one group burns off 0.01g of fat and the other burns 100% more it's like WOW! Not really, as this extra 100% only lowcarb equates to 1g. Is this amount a value that would make a real difference to your goal of bodyweight/composition change? "No way." Yet lowcarb percentage increase is used all the time in the nutrition industry, i.e. product "x" increases fat loss 200% more than placebo; it's a nice play on figures so be aware!!! What we really need to know is the total grams burned at "X" intensity, because it's the total caloric loss that will make the difference when it comes to body composition change. So let's compare some figures using real data... but just before I do, I just want to explain what the term VO2 means. |

| It's a fairly simple concept to grasp in that as exercise intensity increases, the proportion of carb to lipid utilized as an energy source goes up (see fig.1) and vice versa. So when exercise exercise prescription intensity decreases we liberate a greater proportion of fats as our energy source.....but the story does not end there! [figure 1] Simplistic Explanations Lead To Confusion When trying to grasp exercise prescription how the whole issue of how much lipid or carbs is "burned" during exercise, exercise prescription and practices that have been used to derive understanding of the theory and testing, these figures would be useful. Now percentage wise e.g. 40% carbs used and 60% lipid is easy to calculate. The formula is based on something called the respiratory exchange ratio and is the CO2 (carbon dioxide) exhaled / O2 (oxygen) uptake [2]. This is analyzed as you are sitting at rest or exercising and basically the air you breathe in and exhale out is analyzed by a machine (indirect Calorimetry) we won't go into it too much but once you have the values it's a simple division of two numbers. |
