How to Exercise While Intermittent Fasting

Fasted exercise is any workout that’s performed on an empty stomach, whether you’re following an intermittent fasting plan or working out in the mornings before breakfast. 

Examples of fasted exercise include: 

  • Not eating breakfast before morning barre or Pilates 
  • Waiting a few hours after you eat to go running to avoid occasional GI upset. 
  • Skipping your afternoon snack so you can feel more comfortable in hot yoga 
  • Avoiding eating before your high-intensity treadmill or weights class 

These tips can help you maintain your exercise routine while fasting: 

  • To help support hydration, reduce hunger and promote muscle health, consider supplementing with electrolytes, amino acids and fiber before your fasted workout.*
  • Scale back your workouts, especially when you’re getting started with intermittent fasting. This will give your body time to adjust. 
  • Try to time your workouts to the end of your fasting window, so you can refuel quickly. 
  • Do focus on eating a nutrient-dense meal or snack with some protein soon after a workout.
  • Give yourself permission to adjust your workout length or intensity if you don’t feel up for the full plan that day.
