How to read these results: "Energy Expenditure" shows what your body burned — including carbs from your own glycogen stores. "Fueling Recommendation" shows how much you should eat (exogenous carbs) to replace 50–60% of oxidized carbohydrates, accounting for your glycogen reserves. Substrate split is estimated from intensity relative to FTP. Try adjusting GE to see how it changes.
