It's generally best to schedule workouts before your fast begins or after it ends, according to current guidance.
Understanding Exercise and Fasting
Fasting and exercise both place demands on the body, and combining them requires careful consideration. The primary concern is ensuring adequate hydration and nutrient availability to support both activities safely and effectively.
Best Times to Exercise
According to Dix, “Physiologically speaking, the best and safest time to exercise is when you have the most hydration in your body.” The reference suggests that it's best to schedule your workout before your fast begins or after it ends. This allows your body to utilize available energy and replenish fluids and nutrients post-workout. When you can't replenish water and nutrients, it's best to preserve your limited energy.
Factors to Consider
- Duration of Fast: Longer fasts may require more caution than shorter ones.
- Intensity of Exercise: High-intensity workouts demand more energy and hydration than low-intensity activities.
- Individual Tolerance: Listen to your body and adjust your exercise routine accordingly.
- Hydration: Ensuring you're properly hydrated before and after your fast can help mitigate some risks associated with exercising while fasting.
