Summary
This study looked at whether eating carbohydrates at the end of a pre-exercise meal (instead of at the start) changes how the body burns fat and carbs during exercise and affects cycling performance. Eighteen healthy, trained male athletes ate a standard meal in two different orders on separate days, then did a cycling test. Researchers measured fat burning, blood sugar, and time-trial performance to see if meal order matters.
