Energy balance
Fat oxidation is higher in the fasted state compared to glucose feeding during exercise.
Fasted exercise may be more beneficial for fat oxidation compared to exercising after glucose ingestion.
StrongSupportsmedium confidence
fat oxidation (indirect calorimetry) was higher in the fasted state vs. glucose feeding (P < 0.05).
Why this rating
Based on study design from abstract.
