Which Energy Drinks Are Keto-Friendly? (Stay Fit)

Do you want to begin a keto diet, or you might already have started one?

The ketogenic diet is a metabolic procedure whereby the body becomes efficient at burning proteins and fats to generate glucose (energy) rather than carbohydrates. But when it comes to energy drinks, you may wonder whether you could have one while on a keto diet.

Short answer: Yes, you can enjoy energy drinks while following a keto diet. 

Energy Drinks tend to have high amounts of sugar and calories. However, some energy drinks have low-sugar content or are sugar-free, low-carb, or all-natural ingredients. It sometimes becomes hard to tell which energy drinks are keto-friendly. 

If you want to get knowledge about a keto-friendly diet and some relevant energy drinks, this article is worth reading. So let’s continue to read.

What is a Ketogenic Diet? 

A ketogenic diet, also known as the keto diet, is a low-carb (usually less than 50g each day) and a high-fat diet. Instead of carbohydrates, a keto diet urges the body to give energy by burning fats.

The sharp decline in the intake of carbohydrates directs the body’s shift to a metabolic state known as ketosis. When you start this diet, it can take around 3-4 days for the body to acquire the state of ketosis.

Keto Diet is mainly followed for weight loss and is a straightforward way to reduce belly fat. Ketosis can also turn fats into ketones and helps in providing strength to the brain.

Which Ingredients Are Good and Bad While Following a Keto Diet?


When pursuing a keto diet, the intake of carbohydrates must be minimized. The body to stay in ketosis will be limited to up to 50g per day. 

Most energy drinks usually comprise upwards of 30g of carbohydrates, approximately entirely simple sugar. If you are going to select an energy drink for your keto diet, pay close attention to its sugar content (and carbohydrates).


Protein from eggs

The protein intake suggested is around 50g for women and 60g for men per day. Regardless, it should be seen that these are rough approaches, and they may differ from one individual to other.

Most energy drinks contain 1g or less than 1g of protein per serving. Energy drinks won’t affect your protein intake during the keto diet. 


You can’t consume sugar while following a ketogenic diet. But still, you may enjoy the sweetness by consuming artificial sweeteners, that the body can’t metabolize.

Most energy drinks use artificial sweeteners, which are promoted as sugar-free. These comprise Rockstar Zero Carbs and Red Bull Total Zero.


For a person who follows a keto diet, fat is considered a fundamental energy source. Reducing your fat intake is not very important; you can also eat a lot of fat. 

However, if we talk about health, it is advisable not to eat up extra fats above the conditions for a keto diet. Fat is not usually included in energy drinks, so there will be no effect on your keto diet regarding your energy drink consumption.

Ketogenic Diet and Energy Drinks 


Caffeine is a stimulant that helps by providing energy to your body in a keto diet. However, it is pretty helpful to consume caffeine if you are on a diet.  

Yet, the amount of caffeine you can consume depends on your caffeine tolerance or sensitivity to caffeine. According to this study, caffeine also helps in reducing weight. Of course, you have to do other activities to lose weight, such as dieting or exercising; consuming only caffeine won’t help much. 


No matter how tasty sugar is, it won’t be helpful if you are on a diet. You need to cut down your carb and sugar intake while on a diet. If you consume sugar in your keto diet, make sure not to exceed 50g of sugar per day.

Sugar can be harmful to your health.

Therefore, it is safe to go for energy drinks that are sugar-free or low on sugar. According to AHA, men can consume 36g of sugar, and women 24g of sugar per day. 


While following a keto diet, how many calories you consume is essential. A regular keto diet should only include 980 calories per day. 

Most energy drinks are high in calories but some energy drink brands contain low or even zero calories. Reign Energy Drink and Zevia zero-calorie energy are great options.

Therefore, check calorie content whenever searching for energy drinks for your keto diet.
