10 Best Energy Drinks For A Ketogenic Diet (Stay Fit)

Ketogenic diet or simply, keto diet, is a diet that requires you to decrease your daily intake.

Since your carb and nutrient intake will be much lower when you’re on a keto diet, you will have less energy. So, what can give you quick and easy energy?

Energy drinks, of course! These beverages come in convenient cans, and are packed with loads of caffeine as well as other nutrients to keep you energized.

For a more detailed discussion on energy drinks and keto diets, read on to find out more, from what to look out for to a list of great options.

Let’s get started…

What Is A Ketogenic Diet?

A ketogenic diet is an extremely low carbohydrate diet, which involves a high fat and protein intake instead. Keto diets are mostly practiced for weight loss.

Besides, a ketogenic diet is a very effective way to lose belly fat, as it helps reduce body weight.

Our body mostly provides energy through the carbohydrates we take. But a keto diet provides us with energy through the fats we consume and that are stored in our body.

When the fat in our body is turned into ketones, we achieve a state of ketosis, which increases the efficiency of burning fat.

This is a detailed video where keto is demonstrated properly.

Ketogenic Diet And Energy Drinks


Caffeine is a stimulant, which can help in a keto diet by supplying energy to your body.

It’s quite beneficial to drink caffeine if you’re on a diet, at least according to this article. Keep in mind to consume it in moderation though.

Of course, the amount of caffeine you need will vary depending on your caffeine tolerance and sensitivity to caffeine.

According to this study, caffeine can also help you in weight loss. However, you will need to put in your own efforts to lose weight i.e. (exercising or dieting) as drinking only caffeine won’t help.

With that being said, caffeine is definitely good for you within a limit. Make sure to stick to the FDA‘s recommended daily caffeine limit of 400mg, and you should be safe from any side effects.

Sugar Content

As tasty sugar is, it also won’t be very helpful for you, especially you are on a diet.

If you’re on a diet, it’s obvious that you will need to tone down your sugar and carb intake.

If you’re taking sugar in your keto diet, make sure not to go over 50g of sugar per day.

For reference, American Heart Association (AHA) approves the daily sugar intake of 24g for women and 36g for men.

Thus, it’s safe to assume that you should go for an energy drink that’s low on sugar or doesn’t have any sugar at all.


In a ketogenic diet, the amount of calories you consume is important. An average keto diet should only include about 980 calories from the entire meals in a single day.

While many energy drinks are generally high in calories, there are brands that have few or even zero calories. Thus, when you’re selecting your energy drink for your keto diet, make sure to check the calorie content.


When choosing energy drinks for your keto diet, it would be great to go for a brand that’s both healthy and affordable.

In some cases, a more expensive energy drink isn’t suitable for your diet. On the other hand, you don’t have to compromise on quality by buying cheap energy drinks.

Ultimately, it’s all about paying enough attention to the deals and discounts around you. With the right timing and enough research, you’ll be able to purchase your own pack of energy drinks at a good price.

Do energy drinks stop ketosis?

Energy drinks usually ruin ketosis due to sugar, HFCS. However, businesses such as Red Bull and Monster produce beverages that are suitable for keto that do not contain any sugar. Enjoy energy drinks, stay in ketosis, and get a quick energy boost.

Unless they also contain a lot of sugar, energy drinks won’t cause you to immediately exit ketosis. Because of their low or nonexistent caloric content, sugar-free, keto-friendly energy drinks are generally safe for entering and remaining in ketosis and in that form of diet.

Which energy drink is best for workout?

The best energy drink for workout can vary depending on personal preference and individual needs. Some factors to consider when choosing an energy drink for a workout include caffeine content, electrolyte content, and ingredients such as B-vitamins and amino acids that can help support energy and endurance.

Some popular options include Gatorade Endurance, BSN N.O.-Xplode Pre-Workout Supplement, and GU Energy Gel. It’s important to note that some energy drinks can be high in sugar and other additives, so it’s crucial to carefully review the ingredient list before choosing a product.

What puts you in ketosis fastest?

Achieving ketosis, a metabolic state where the body burns fat for fuel instead of carbohydrates, typically requires a significant reduction in carbohydrate intake. The fastest way to enter ketosis is through a strict ketogenic diet, which limits carbohydrates to around 20-50 grams per day.

Other methods that can help expedite the transition into ketosis include intermittent fasting, exercise, and increasing physical activity. Intermittent fasting can deplete glycogen stores more quickly, leading to an earlier onset of ketosis. Additionally, engaging in moderate to intense exercise can accelerate the depletion of glycogen and promote ketone production.

How long can you stay in ketosis safely?

The length of time an individual can safely stay in ketosis varies depending on factors such as their overall health, medical history, and specific nutritional needs. While some people may follow a ketogenic diet for an extended period, others may choose to do so for shorter durations.

However, prolonged or strict adherence to a ketogenic diet may have potential risks and side effects, such as nutrient deficiencies, constipation, and potential impacts on kidney function. It’s crucial to maintain a well-balanced and varied diet to avoid any potential adverse effects.

Can You Drink Energy Drinks If You Are On A Keto Diet?

You can drink energy drinks even if you are on a ketogenic diet.

Of course, while it’s perfectly okay to drink energy drinks on a keto diet, you must make sure to choose the right brands. After all, the main goal in a keto diet is to consume as few carbs as possible.

As such, sugar-free energy drinks or low-calorie energy drinks are highly recommended for a keto diet.

These energy drinks usually use artificial sweeteners instead of sugar, which keep their calorie and carb content low. Plus, you can satisfy your sweet tooth without the unnecessary calories with sugar-free energy drinks.

Of course, those aren’t the only options you have. You can go for energy drinks with some sugar in them, provided their calorie and carb content are still manageable.
