Is It Safe To Exercise On An Empty Stomach?

While some fitness enthusiasts swear by fasted exercise (exercising on an empty stomach), others recommend a modest pre-workout meal. It’s all a matter of personal taste. 

While doing out on an empty stomach might help you burn more fat and reduce weight, it can also have some negative consequences.

Working exercise when fasting (early in the morning or 2 to 3 hours after eating) may cause the dreaded ‘bonk,’ which is an athlete’s word for the abrupt sense of light-headedness and lethargy caused by low blood sugar. It is an unpleasant sensation that must be avoided at all costs!

Fortunately, if you pick a high-quality pre-workout supplement with solely natural components supported by scientific study, this shouldn’t be a problem.

The Advantages of Using a Pre-Workout Supplement

A pre-workout supplement’s vitamin and mineral combination, as well as the addition of substances like L-citrulline (a naturally occurring amino acid that promotes blood flow to the muscles), enhances your energy levels, allowing you to work harder and at a greater intensity. 

L-Citrulline may also aid muscle growth by providing that additional push to finish more repetitions, enhancing your post-workout muscle pump and, over time, your muscular mass.

Red beetroot powder, for example, is an excellent pre-workout substance since it is believed to deliver a nitric oxide boost that may boost your exercise performance to new heights. 

Regardless of the supplement you pick, taking a pre-workout on an empty stomach will help you get the most out of it since it will be absorbed quicker. 

With no food in your digestive track to contend with, all of those wonderful vitamins and minerals can go to work faster, which is great for your exercise!

Ingredients to Be Wary Of

Most pre-workouts are meant to be consumed on an empty stomach, however specific substances must be avoided to prevent undesirable side effects. 

Caffeine is often used in pre-workout drinks to boost energy and concentration. If you take it on an empty stomach, it will enter your system quickly, so be careful if you are caffeine sensitive.

Caffeine may trigger jitters and energy drops even after you’ve eaten a meal, so if you’re not cautious, these side effects may be more severe.

There are stim-free pre-workout supplements on the market, as well as ones with a moderate amount of caffeine (less than 100mg per serving), as compared to the megadoses of 200mg or more per serving found in certain pre-workouts.

Synthetic chemicals or artificial sweeteners may be included in lower-quality pre-workout pills, which may produce unpleasant side effects such gastrointestinal discomfort [1]. So, conduct your study so you can avoid such items and instead choose for a natural pre-workout.

It’s also worth noting that if you do wind up with low blood sugar after a fasted exercise, a pre-workout won’t magically make the dizziness and nausea go away; in fact, it’ll probably make it worse. The word ‘pre’ is crucial in a pre-workout!!
