Does Pre-Workout Break a Fast?

Are you someone who wants to enhance your workout performance while fasting? It's understandable that you may be wondering if pre-workout supplements will break your fast.

Fasting involves not consuming anything with calories for a specific period of time, while pre-workout supplements are drinks or pills that you take before exercising to boost your performance.

Whether or not pre-workout breaks your fast depends on the type of fast you're doing and the ingredients in the supplement. If you're following a water fast, taking a pre-workout will break your fast. However, if you're doing Intermittent Fasting, which limits your calorie intake, taking pre-workout supplements with low-calorie, non-nutritive ingredients may not break your fast.

So, if you're thinking about taking pre-workout supplements during your fast, it's crucial to know how they'll affect your fast, depending on your specific fasting goals and the ingredients in the supplement.

What Are Pre-Workout Supplements?

Pre-workouts or pre-workout supplements are dietary supplements that offer energy to their users. These supplements result in energy improvement during the workout. It also helps in faster recovery.

Many studies have demonstrated the link between multi-ingredient pre-workout supplements and improved performance [1].

These pre-workouts come in powder or pill form that you can take with water. You will find different ingredients in a pre-workout that work together. It creates a formula that helps in improving focus, gaining strength, lowering fatigue, and increasing lean body mass.

Pre-workout supplements and fasting’s effects on your body depend on the type of fasting you do and the ingredients in the pre-workouts. Consuming a pre-workout would break your fast, especially if you’re observing water fast. That’s because you’re drinking a non-water substance.

Are you observing an intermittent fast where you restrict food intake for a specific hour every day? A pre-workout supplement’s effect will depend on the ingredients.

Remember that pre-workout supplements containing calories from fat, protein, or carbohydrates could break your fast by offering energy to the body. Nonetheless, it may not break your fast if the supplement only has non-caloric ingredients like amino acids or caffeine.

Can You Take Pre-Workout Supplements While Fasting?

Supplements such as minerals and vitamins won’t have calories. However, the way you eat them matters.

Supplements in the form of gummies have hidden calories. During your fast, take supplements without unnecessary ingredients or added sugars.

Some individuals prefer to fast with small calorie allotments. In that case, you can eat gummies during your fast.

So, Does Pre-Workout Break Your Fast?

During intermittent fasting, your body shifts from using glucose as its primary energy source to using stored fats. When glucose isn’t available, the liver converts stored fats into molecules. That molecule is ketones.

Does your pre-workout supplement have calories from fat, protein, or carbohydrate? Then it will provide your body with glucose, breaking the fast and interrupting the shift to ketosis. In that case, your body won’t burn the stored fat for energy. Instead, it will use the glucose from the pre-workout supplement.

Meanwhile, does your pre-workout supplement only has non-caloric ingredients like amino acids or caffeine? It would not break the fast. That’s because those ingredients may boost energy without providing any glucose to the body. It allows it to continue using the stored fat for energy.

Remember that the effects of fasting and pre-workout supplements can vary from one person to another. The ideal approach will depend on individual goals and needs.
