Something happens when you start noticing successful results with intermittent fasting (IF)...

You start to excessively micromanage your diet down to the micronutrient degree to ensure that you keep noticing positive results with intermittent fasting.

In other words, you get a little obsessed.

However, the downside to this sort of obsession is the rising self-doubt surrounding other healthy habits and fitness strategies that have previously worked just fine.

You start to wonder if, for example, eating certain vegetables interferes with your fasting results...

...or if you should discontinue taking certain health supplements for fear of disrupting your fasting metabolism.

You forget that the whole point of intermittent fasting isn’t to just succeed at fasting but to improve your health.

Though the metabolic benefits are complex and wide-ranging, don’t make intermittent fasting more complicated than it needs to be.

With that in mind, asking whether or not a pre-workout supplement breaks your fast isn’t as important as asking, “Does a pre-workout assist intermittent fasting in helping me achieve my health and fitness goals?”

The answer to this is, yes, with the Best Pre-Workout for Intermittent Fasting, you may take your intermittent fasting results to the next level.

And in this article, we not only explain how to get better IF results with a pre-workout but also what you should look for in an IF-friendly pre-workout stack…

…And, okay, sure: we also provide a detailed list of a few natural pre-workout ingredients that you can take without breaking your fast.

The Beginner’s Guide on Fasting with a Pre-Workout

Let’s start here: What is a pre-workout supplement?

A pre-workout supplement is a supplement taken prior to working out. That's the short answer.

Below is a more complete answer. 

A pre-workout is a performance enhancement supplement taken immediately prior to working out.

They are designed to improve various measures of exercise performance, including:

  • Energy and Endurance
  • Strength and Stamina
  • N.O.-Boosted Muscle Pumps
  • Stress Resistance
  • Mental Focus and Intensity

Pre-workouts are special supplements designed to stimulate a workout-ready physiology for maximum performance on both aerobic and anaerobic exercise activities.

Likewise, intermittent fasting is a dieting strategy designed to supercharge your metabolic faculties to be more efficient at burning fat and building new muscle,[1] making intermittent fasting and pre-workout supplementation a potentially synergistic combination.

So long as pre-workout supplements don’t interfere with the metabolic benefits of intermittent fasting, as many people fear they do.

But do they?

Before answering that, let's answer the question below.

Is It Okay to Exercise While Fasting?

Is it better to exercise in a fasted state or a well-fed state?

In other words, should you eat prior to working out or hit the gym on an empty stomach?

Well, it depends.

If you’re trying to burn MORE fat in LESS time, certainly fasted training, or fasted cardio, may help.

The theory behind fasted cardio that has taken the fitness community by storm lately is this: without food fuel readily available to convert to energy, the body resorts to stored fat for energy fuel.

This isn’t an unfounded theory. There is research that validates fasted cardio as an effective, efficient fat-burning strategy:

One study on the effects of fasted vs fed-state exercise on performance and post-exercise metabolism observed heightened fatty acid metabolism under fasting conditions, suggesting of “potential beneficial metabolic adaptations that fasted exercise may induce in peripheral tissues.”[2]

However, in that same study, pre-working feeding was found to bolster prolonged aerobic performance, suggesting that a well-fed exercise may have an endurance advantage over the fasting exerciser.

Fasted cardio may improve metabolic energy expenditure and fat loss rates, yet research suggests this comes at the cost of exercise endurance and intensity.

Because prolonged absence of food intake reduces circulating blood sugar (glucose) levels, muscle glycogen levels drop, encouraging the body to rely more on fat to fuel your workout activity.[3]

Yet, conversely, heightened glycogen levels correlate with heightened muscle endurance.[4]

Likewise, glucose fuels willpower, or self-control,[5] which is a core psychological factor in engaging and sustaining a high-intensity workout in the first place.

What this means then is that while, yes, exercising on an empty stomach is an effective fat-burning strategy, it also requires a significant amount of additional willpower to overcome the physiological and psychological barriers that come with low circulating glucose levels.

Which is why having fasting-friendly workout supplements is practically a necessity when it comes to exercise and intermittent fasting.

Why You Should Take a Pre-Workout While Fasting

First of all, whether fasting or not, if you’re working out, you should be taking a pre-workout supplement.

Granted, if you haven’t been taking a pre-workout all this time, there’s likely a good reason for it: many pre-workout supplements are full of artificial crap.

And much of that artificial crap may actually interfere with your intermittent fasting metabolism—not to mention many other aspects of your health and fitness.[6]

However, a natural, effective pre-workout supplement, one that uses only all-natural ergogenics without any artificial additives, is worth the investment while intermittent fasting for a few reasons:

  • Pre-workouts replenish muscle ATP cell energy for an additional boost on muscle strength, stamina, and endurance.
  • Antioxidant and acid buffering pre-workout supplements help reduce the negative “endurance-killing” consequences of fasted training.
  • Nitric oxide (N.O.) boosting pre-workouts may further improve muscle performance by increasing circulation and, thus, delivery of oxygen and nutrients to muscle tissue.

In other words, pre-workout supplements may help prime muscle performance via non-glucose pathways that protect exercise endurance without breaking the fast.

By combining a pre-workout with fasted training, you can burn MORE fat in LESS time while SAVING your workout performance from the endurance-diminishing aspects of fasting.

That sounds very much like a win-win-win.

The Fitness Benefits of Intermittent Fasting

Combined with exercise, intermittent fasting may have profoundly positive effects on exercise health and performance.

To name just a few fitness advantages of intermittent fasting, research has linked the following health benefits to fasting:

  • Increased growth hormone secretion with exercise.[7]
  • Encouraged reliance on fat metabolism with resistance training.[8]
  • Better regulation of inflammatory response pathways.[9]
  • Improved insulin sensitivity.[10]
  • Enhanced neuroplasticity and cognitive health.[11]

And more. Especially given the direct and indirect systems that overlap with these health systems.

Sustained by a healthy, whole-food diet and exercise, intermittent fasting may help keep the mind sharp and the body primed for high levels of daily productivity.

Here’s a Tip: Exercise in the Morning

Of course, to fast is to remain in a state of heightened stress and discomfort.

Eating is a form of comfort, after all. Hence why we “stress” eat when the going gets rough.

With that in mind, exercising first thing in the morning seems to be the best way to go.

Morning exercise appears to limit the daily discomforts of fasting, while also limiting your daily energy intake in general:

As one study has demonstrated, fasted training in the morning not only increases fat oxidation (fat burning) during exercise but also decreases 24-hour energy (food) intake, as the body remains primed to burn fat for energy throughout the remainder of the day. Based on these findings, the study’s researchers concluded that “Completing exercise in the morning in the fasted state may have implications for weight management.”[12]

What to Look for in a Pre-Workout for Fasted Training

Not all pre-workout supplements are equal.

Some pre-workout stacks are better than others, and only one pre-workout supplement is the best.

With that in mind, the Best Pre-Workout for Intermittent Fasting improve your fasted training results by boosting:

Natural ATP Muscle Energy

There are typically two ways that pre-workout supplements increase energy: (1) with stimulants (namely caffeine), and (2) with creatine, an organic precursor to ATP energy production.

Because stimulants tend to feel really good, many cheap, inferior pre-workout supplement stacks tend to over-prioritize the stimulatory pathway to boosting energy, often as a strategy to mask the otherwise ineffective qualities of their formulas.

Natural, effective pre-workout supplements, on the other hand, toss the stimulants for creatine, a reliable and well-researched ergogenic that supports training intensity, muscle growth, and recovery by:[13,14]

  • Recharging ATP energy molecules required to power muscle fibers during high-intensity exercise and repair worn-out muscle tissue after exercise.
  • Stimulating insulin-like growth factor 1 (IGF-1), an anabolic protein that triggers the growth and development of lean muscle mass.
  • Buffering the formation of lactic acid buildup within muscle tissue, thereby extending time of muscle performance until failure.

Given that creatine gradually builds up in muscle tissue, supplementing creatine on a daily basis may help mitigate the muscle-draining effects of fasted training over time.

Best Creatine for Intermittent Fasting: Creapure® pH10

Creapure® pH10 is highly potent and bioavailable creatine form that more readily absorbs into muscle tissue to deliver its ATP energy enhancement benefits.

Typically served in excessively high dosages, creatine often comes with GI discomforting side effects, such as bloating and stomach upset.

However, by cranking up the potency, Creapure® works in smaller dosages, saving you the gut ache while delivering the same ATP energy boosting benefits.

Nitric Oxide (N.O.) Production

Second only to perhaps creatine, the most popular and important pre-workout supplements are nitric oxide (N.O.) boosters, given the importance of N.O. to facilitating vasodilation.

By relaxing the smooth muscle of blood vessels, N.O. helps increase circulation, thus promoting the sacred “muscle pump” desired by bodybuilders and aerobic.

Aesthetically, the muscle pump looks great; however, practically speaking, the muscle pump also signals that adequate oxygen and nutrients are being delivered to muscle tissue.

For a long time, L-arginine was viewed as the best N.O. booster, given that this amino acid is a direct precursor to nitric oxide production.[15]

However, orally supplemented L-arginine fails to sufficiently bypass digestion in the liver, which is why many exercisers have turned to L-citrulline, the precursor to L-arginine.

By bypassing digestion in the liver, L-citrulline supplements have a better survival rate than L-arginine. Once in the body, L-citrulline converts to L-arginine, which in turns promotes nitric oxide production for enhanced “muscle pump” activity.[16]

As such, L-citrulline is easily the superior N.O. booster for enhanced muscle strength and endurance.

Best L-Citrulline for Intermittent Fasting: Kyowa Quality® L-Citrulline

Kyowa Quality® L-Citrulline is an ultra-pure L-citrulline form manufactured by using a proprietary plant-based fermentation process.

As an exceptionally pure and clean brand of L-citrulline, Kyowa Quality® L-Citrulline is one of the best N.O.boosters—if not the best—for natural exercise performance enhancement.

By naturally promoting blood flow to hard-working muscles, L-citrulline may help overcome the muscle-draining conditions of fasting for a longer, better workout.

Lactic Acid Buffers

You know that burning sensation that builds up in your muscle tissues once you’ve reached the higher reps of a set? That’s lactic acid.

As we perform strenuous exercise, we breathe faster to meet the heightened oxygen demands of our tired muscles. Progress in aerobic exercise is essentially measured by the oxygen demands of our muscles per physical output. As we increase our aerobic fitness, we require less oxygen to perform the same levels of output.

When energy output exceeds oxygen input, lactic acid builds up in the body as a response to the anaerobic (non-oxygen) production of energy.[17]

The heightened acidity in muscle tissues brought by lactic acid buildup not only provides a burning sensation but may also have a catabolic (breakdown) effect on muscle growth.

This mainly explains the popularity of supplementing beta-alanine, a precursor to the dipeptide molecule carnosine that seems to act as a muscle-alkalizing pH regulator against muscle-damaging lactic acid buildup.[18]

Highly concentrated in fast-twitch muscle fibers, carnosine seems to be particularly effective at increasing muscle power during high-intensity anaerobic exercise, such as weightlifting and sprinting. As such, beta-alanine is a powerful tool for intermittent fasters whose workouts entail high levels of anaerobic activity.

Best Beta-Alanine for Intermittent Fasting: CarnoSyn®

The only patented beta-alanine on the market backed by clinical research, CarnoSyn® is the go-to beta-alanine brand for pre-workout exercise performance enhancement.

With over 55 studies having been performed on CarnoSyn®, this is by far one of the most trusted beta-alanine ingredients among both supplement manufacturers and customers. It’s also the only beta-alanine with New Dietary Ingredient (NDI) status and a self-affirmed GRAS (Generally Recognized as Safe) status, making CarnoSyn® one of the best pre-workout supplements overall for a natural and safe boost on fitness and performance.
