Document Summary

When rer reaches 1. 0 this is where you use cho glucose completely at maximal high intensity. In fat oxidation, you need a lot more oxygen to break down fat bonds because there are more carbon bonds. To burn fat therefore takes more oxygen and takes longer to be used as an energy source compared to glycogen/glucose/cho. Rer is 0. 7 this is specifically using fats and oxidizing fats when you are at rest. Majority of what you burn at rest is fat. Rer and % of energy of cho or fats. Any number between 0. 7-1. 0 is a mixture of fuel that you are using. For example, 0. 85 will be a mix of cho and fat usage. This is measured by the metabolic rate where you look at the o2 and co2 being exhaled. Digestion = digesting complex compounds into simple compounds (cho to simple sugars/proteins to amino acids)
