Fasted Exercise Shifts Fuel Use But Not Necessarily Fat Loss
- Fasted workouts can increase reliance on stored fat because recently eaten carbohydrates aren't available.
- In practice this acute increased fat use doesn't guarantee long-term weight loss because overall energy balance drives fat loss.
Limit Fasted Sessions To Short Moderate Workouts
- Try short, moderate sessions like 15 to 20 minutes of light jogging, gentle cycling or yoga if you exercise fasted.
- For more intense workouts, eat a small pre-exercise snack to avoid performance drop, dizziness, or loss of balance.
Comfort Is A Common Reason People Choose Fasted Workouts
- A practical benefit of fasted training is reduced bloating or heaviness when exercising soon after a meal.
- L'Equipe notes comfort as a common reason people choose morning workouts before breakfast.
