Can I Have Pre Workout While Fasting: 10 Secret Benefits Of Fasting

Can I Have Pre Workout While Fasting? Many people wonder whether they can have a pre workout while fasting. The short answer to that question is yes! Mixing fast with your pre workout dose is not an issue. It’s perfectly fine to go on with your fast and then take in a pre-workout supplement containing caffeine or any other stimulant for that matter.

As long as your fast is of a decent length, it’s not going to do any harm. However, there are also some downsides to taking pre-workouts while fasting. The most obvious downside is that you will miss out on the boost in muscle mass and strength from those crucial nutrients.

There are also positive points to consider when asking if you can continue a fast and still take in your pre-workout on the flip side. If you want to use the energy boost that is likely to come from taking a pre-workout during fasting hours towards furthering your motivation for workouts. Keeping a fast would be an excellent option.

What are the benefits of fasting?

There are many benefits of fasting. It is one of the best ways to clear out your system and eliminate harmful elements in your body. Fasting or intermittent fasting is done by very many people around the world.

  1. Fasting promotes autophagy, the body breaking down and eliminating its own cells that are old or damaged. What results is a fresher and healthier body. This happens when you fast for at least 24 hours because it takes time to break down the cells completely.
  2. It activates an important antioxidant called glutathione, which fights free radicals that cause damage to the cells.
  3. Fasting reduces oxidative stress and inflammation, which can lead to a longer life and improved brain function.
  4. The autophagic process produces adenosine triphosphate (ATP). It is a source of energy that the body can use without having to eat.
  5. Fasting leads to weight loss because you are not taking in any new calories. Still, you’re also not burning off too much (because at the fasting state, your metabolic rate drops).
  6. It protects against heart disease by lowering cholesterol levels, triglycerides, and blood pressure while raising HDL and beneficial HDL.
  7. Fasting also improves brain function by increasing BDNF (brain-derived neurotrophic factor) levels.
  8. It protects the body from developing cancer since it reduces both oxidative stress and inflammation.
  9. Fasting connects your cells to remove toxins that can cause cancer.
  10. It also keeps your DNA healthy by slowing down cellular aging.

Can I Have Pre Workout While Fasting?

Pre-workouts are used to enhance the physical performance of a person. They contain many ingredients, each with its own role in enhancing performance and energy levels.

So can you have a pre-workout while fasting? Yes, but it’s important to focus on your fast and not be distracted by making gains in muscle mass or performance.

As I said earlier, if you’re fast is of a good length (at least 24 hours), it’s not going to be an issue at all. However, longer fasts are typically better since they give your body the chance to start on its own autophagy processes and clear out your system of toxins. Here’s how fasting works:

How long should you fast for before working out?

This would depend on your goal. A workout after a 24 hour fast may be quite effective for fat burning and muscle growth. Doing cardio will help burn off extra fat. At the same time, resistance training will increase the number of lean muscles in your body. This has been proven by research. Pre-workouts work better with shorter fasts, so it’s important to keep that in mind.

Now, you must know what ingredients can be of concern when fasting:


This is a substance used for building lean muscle mass. It is an amino acid which means it includes nitrogen. It also contains water, and creatine mixes with your blood (creatinine) and is circulated to cells. It works by increasing the size of your muscle fibers.


It will definitely increase energy levels, especially when you’re working out.


This is a simple sugar that provides instant energy.

L-Arginine (Amino Acid)

This is an essential amino acid that plays a huge role in the growth and repair of muscle tissue. It’s also considered to be a precursor for nitric oxide.

Citrulline (Amino Acid)

This is another amino acid with a great effect on enhancing physical performance.



This is also an amino acid with a positive effect on muscle strength and endurance.

Creatine Monohydrate (Amino Acid)

This is one of the most popular ingredients in pre-workouts because it helps build lean muscles, increase workout performance, and cut recovery time.

Caffeine Anhydrous

This ingredient increases energy levels and alertness by stimulating the central nervous system. However, it is not safe to consume in large amounts.

Beta-Alanine (Amino Acid)

This ingredient increases the amount of carnosine in your body, which buffers lactic acid build-up and lowers the risk for cramps.

DiCaffeine Malate

This ingredient will increase energy levels more stable than caffeine since it takes longer to be broken down.

High Dose B-Vitamins

This ingredient will increase alertness and help you get through your workout if you feel tired. It will also help protect against fatigue.

What to eat after a workout?

If you have a pre-workout snack, it’s best to eat something with protein and carbohydrates since they are known to slow down the breakdown of amino acids in your body.

Foods that fit this bill include:

Low Fat Dairy Foods

They contain good amounts of casein proteins, making sure your body absorbs all the amino acids in them.


These contain a good amount of leucine, which is free-form amino that helps increase muscle tissue.


Whey Protein Powder

This is one of the most popular post-workout supplements available, containing high amounts of branched-chain amino acids, leucine, and other essential amino.

Soy Protein Powder

The glutamine content in this supplement increases muscle synthesis. The number of essential amino such as lysine is high enough to promote protein synthesis in your body.

Whey Isolate Protein Powder

This protein powder contains high amounts of leucine, which helps with muscle-building.

Muscle Meals or MRP (meal replacement powders)

These supplements are good choices because they have a lot more ingredients than just protein and carbohydrates. They include other vitamins and minerals that can help the normal recovery process.

Peanut Butter on Whole Grain Bread

This snack contains plenty of good fats and protein, which is perfect for the post-workout period.

Yogurt with Berries

The carbs in yogurt plus the carbs and proteins from the berries will replenish glycogen stores and amino acids. It will also boost immune function.

Carbs + Protein Smoothie

This smoothie would be a great choice because it has plenty of carbs and proteins, which are extremely important after working out.

How much protein do you need?

This really depends on your activity level. For example, strength training athletes need to consume a lot more protein than usual because they lose muscle mass while exercising.

The post-workout period is the best time to take in proteins. It will help get your muscles back into shape faster by increasing amino acids and reducing muscle protein breakdown.

The Bottom Line

Can I Have Pre Workout While Fasting? It sounds like a good idea in theory, but this question is not so straightforward. When trying to figure out what you should eat after your workout. The most important thing is determining how intense it was. And at what point during your routine did you consume pre-workout supplements.

Suppose you had consumed any type of stimulant before hitting the gym or running on the treadmill. In that case, you should take some time off from consuming food since these stimulants will make sure that all of those nutrients are burned up instead of being used as energy.

However, if you didn’t have anything with caffeine in them beforehand (or drank decaf), then feel free to grab a snack or meal right after your workout. This will help your body recover and start building muscles before it starts breaking them down again.

Make sure to only consume food with plenty of protein and carbohydrates. Because this is the easiest way for your body to absorb amino acids, which are crucial for muscle tissue recovery.
