You’re loving that keto life, except for one thing: Your favorite jolt juice is packed with carbs.

Good news! Pre-workouts have come a long way. You can have your keto and feel swole too.

Keep scrolling for more info on what a “pre-workout” is, how it can fit into a keto lifestyle, and the perks of taking a pre-workout, plus a roundup of the best keto pre-workout supplements and snacks of 2021.

Just want the fast list? Here you go:

Pre-workout supplements are created to pump up your next sweat sesh. Most formulas come as a powder to mix with water and chug 30 minutes before your workout.

Pre-workout formulas are standard for professional athletes, but they’ve also caught on in the mainstream.

Since they’re a dime a dozen on the market, it can be tough to figure out which ones are legit. It also takes time to find the one that’s best — and safest — for your goals.

The ketogenic diet calls for high fat, low carb eating to encourage your bod to use its fat stores for fuel. The basic keto eating breakdown is 55 to 60 percent fat, 30 to 35 percent protein, and 5 to 10 percent carbohydrates.

When your body doesn’t have carbs for energy, your liver steps in. It converts your fat into something called ketones, which can be burned for energy instead. Once your body starts this fat-torching process, it’s called “being in a state of ketosis.”

For folks on the keto diet, it’s important to choose a pre-workout that will *keep* their bodies in ketosis.

TBH, the answer varies wildly from product to product. You will see some common ingredients in both mainstream and keto-friendly pre-workouts.

Amino acids


Exactly what you think: Boost your energy to improve your performance.

B vitamins

From thiamine (B1) to cobalamin (B12), the B vitamins = brain and blood cell juice to help your body run on all cylinders.

Artificial sweeteners

Stevia. Saccharin. These guys make your jolt juice tasty.


Beta-whaaat? Keto pre-workout formulas differ from other formulas in two ways: They typically have no more than 1 carb per serving *and* they include beta-hydroxybutyrate.

Recent research suggests that pre-workout formulas with electrolytes and beta-hydroxybutyrate boost exercise performance by more than 10 percent for folks in ketosis.

Other common ingredients

Most pre-workout formulas include salts to replenish electrolytes lost to sweat, natural or artificial flavors, and sometimes a blend of herbs or vitamins.

WTF is a “proprietary blend”?

This is perhaps the biggest issue with pre-workout powders and pills. The FDA doesn’t evaluate the safety, effectiveness, or quality of dietary supplements or their ingredients. That includes the *amounts* of ingredients in so called “proprietary blends.” So, you could be getting more (or less) of a vitamin, mineral, or other ingredient than you bargained for. Pretty murky stuff, huh?

The best way to verify the nitty-gritty of pre-workouts with proprietary blends is to shop for products that have been certified by a third-party company.

Of course! Like most supplements, pre-workouts come with a side of research-backed results and personal claims.

The benefits

Because of the caffeine content, most pre-workout supplements make your energy soar. And being wired AF increases your chances of going harder, faster, stronger.

Caffeine’s benefits go beyond the obvious too. Research indicates that it boosts exercise performance and decreases post-workout muscle soreness.

The ingredients listed above — essential amino acids and performance-boosting beta-hydroxybutyrate — will also increase pump and help you smash your workout goals.

The downsides

Well, there’s that whole “proprietary blend” thing. These blends are merely FDA-regulated, so there’s the potential for mystery types and amounts of ingredients.

Pre-workout supplements will never be as straightforward as a simple pre-workout egg, avocado, or other whole-food snack. And even when dosing on essential amino acids and vitamins, you run the risk of getting too much of a good thing.

Finally, there’s always a chance that your pre-workout won’t mix well with your other supplements or prescription meds. Err on the side of caution and talk to your doctor before taking a new pre-workout formula.

Maximizing your workout is all about preparation.

Timing is everything

Most pre-workout formulas are designed to be taken 20 to 30 minutes before exercising. This gives the ingredients time to take effect.

If you’re craving a caffeine jolt, timing gets a bit trickier, because caffeine takes effect 45 to 60 minutes after you consume it.

Your best bet? Chug that pre-workout drink 30 minutes before your warmup. The amino acids and vitamins will already be surging through your system, and the caffeine will kick in soon after.

When to switch up the intensity

You’ll typically choose a pre-workout supplement that has the right ingredients for your specific goals. Some ingredients give you major pump for lifting, while others boost your endurance.

Pick a pre-workout that fits your exercise style and goals.

Wanna support your pump during ketosis? Look for beta-hydroxybutyrate.

Need major jolt juice for HIIT? Go for the caffeine and B complex.

Hoping to beat your lifting record? Grab a pre-workout with creatine, athletes’ favorite ingredient for boosting strength and power.

It’s a big deal that pre-workouts aren’t FDA-approved. If yours is stuffed with pointless fillers, you’re wasting your cash at best. At worst, you could be harming your body instead of pumping it up for peak performance.

To be safe, professional or student athletes should get their pre-workout supplements approved by a coach or dietitian.

Not a pro? Ask your doc about any harmful interactions with your other supplements or prescription meds.

Supplements, bars, and fat bombs have their place, but the foundation of a killer set of reps is good nutrition. Keto puts the kibosh on carb-loading, so figuring out a variety of pre-workout snacks and meals can be a little tricky.

Building a meal from the keto basics — high fat, moderate protein, and few to no carbs — will get you in the zone for a run or HIIT class. Here are some ideas for supplement-free pre-workout noshing.

If you’re an early bird at the gym…

  • Opt for a deliciously messy, meaty breakfast sandwich that swaps in two sausage rounds for the classic English muffin.
  • Try an egg omelet stuffed with veggies, avocado, and a protein like crumbled sausage or diced chicken.
  • Whip up some cauliflower hash browns with a side of roasted veggies. Savory perfection!

If you’re a lunch break gym-goer…

Meal-prepping your keto lunches is key to sticking to the meal plan! Some of our faves:

If you’re a p.m. powerhouse lifter…

Pro tip: Whip up a few keto-friendly dinners on Sunday so you can heat them up between the office and your spin class. Or keep a list of easy keto dinners you can make in 30 minutes flat (yes, really).

  • Loaded cauliflower, anyone?
  • Keep it simple with a slab of meat (fish, chicken, beef, turkey — pick your poison!) and a side of sautéed veggies.
  • This keto shrimp scampi is the bomb.

Pre-workout products make a lot of claims, from boundless energy and muscle recovery to better gains and mental focus. A quick study of the ingredient list will give you a good idea of whether those claims are science-based or hype.

Keto pre-workouts are designed to give you maximum performance boost with minimal carbs. It’s all about working out while staying in ketosis.

Remember, the point of any pre-workout is to improve your performance. So if your keto pre-workout gives you a headache, the jitters, or diarrhea, stop taking it! There are many pre-workout formulas on the market, and it might take some trial and error to figure out what works for you.

In a pinch, let food by thy medicine pre-workout. From keto-friendly nibbles to fat- and protein-heavy meals, there are food-based ways to boost your gains.
