Many people are looking for answers about whether pre-workout supplements are compatible with intermittent fasting – and the answer is both yes and no.

In fact, it’s better to avoid pre-workout supplements while intermittent fasting.

What is Intermittent Fasting?

Intermittent fasting is a dietary pattern that involves cycles of fasting and eating. It is an eating pattern that cycles between periods of fasting and eating. During the fasting periods, you don’t consume any food or drink, except for water. During the eating periods, you can eat whatever you want. This helps your body to burn fat and improve overall health.

Why Is Pre-Workout Not Recommended For Intermittent Fasting?

Pre-workout supplements typically contain stimulants and other ingredients that can raise your insulin levels.

Additionally, pre-workout supplements can cause an energy spike that can make it more difficult to focus on your workout.

Other Pre-Workouts That Can be Used While Intermittent Fasting

Pre-Workout can be used while intermittent fasting but you just need to read the packets and make sure there’s no ingredients that’ll break you out of your fast. For instance, if your pre-workout supplement has 5 calories per serving (like Pulse), that’s probably fine, as it will have almost no impact on insulin levels. Water, plain tea, and black coffee are okay during a fast because they have zero calories. There’s some debate over diet colas, but technically zero-calorie drinks can be allowed if consumed in moderation.
