Whether doing sport while fasting is good depends on your individual goals and how you manage potential downsides. Fasting and exercising present both benefits and challenges.
Potential Benefits of Exercising While Fasting
- Increased Caloric Deficit: According to research, "Training while fasting increases your caloric deficit which is an essential aspect of weight loss." This can be beneficial if your goal is weight loss.
Potential Downsides of Exercising While Fasting
- Decreased Exercise Performance: The same research notes that "Exercising on an empty stomach can negatively affect the quality of your workout." This means you may not be able to perform as well, lift as much weight, or run as fast.
Considerations
To decide if exercising while fasting is right for you, consider the following:
- Your Goals: Are you primarily focused on weight loss or performance gains?
- Intensity of Exercise: Lighter activities like walking or yoga may be fine, while high-intensity workouts might suffer.
- Your Body's Response: Pay attention to how your body feels. If you experience dizziness, lightheadedness, or extreme fatigue, stop and adjust your approach.
- Hydration: Drink plenty of water before, during, and after your workout, especially when fasting.
- Electrolyte Balance: Consider supplementing with electrolytes to maintain proper fluid balance.
