Benefits of Drinking Energy Drinks While Intermittent Fasting

There are many benefits of drinking energy drinks while intermittent fasting.

It may be difficult for those new to intermittent fasting to jump into a fasting regime and not have sufficient energy to carry on with their daily activities. 

Consequently, consuming an energy drink before your fast begins (or after your fast ends) would provide you with sufficient energy to last throughout the day.

The reasoning makes sense; if you are eating less, you might feel weaker or lack energy during certain periods of the day.

For intermittent fasting to be worthwhile and reach your goals, make sure you drink a low-calorie energy drink containing low amounts of sugar, caffeine, and fat.

Do Energy Drinks break intermittent fasting?

Consuming a sugar-free energy drink does not break your intermittent fasting.

However, if you are someone quite rigorous about their diet, it’s important to avoid drinks during fasting as they contain artificial sweeteners.

Caffeine: 80mg

Calories: 10

XS energy drink is one of the best energy drinks you can have while intermittent fasting. This energy drink contains only ten calories, has moderate caffeine content, and has zero sugar in its formula, making it a perfect choice for you.

This energy drink is good for intermittent fasting.

Furthermore, this energy drink has multiple vitamins and minerals in its formula, which will help you in your intermittent fasting. Moreover, this energy drink comes in two different flavors, completely caffeine-free. Here are the caffeine-free flavors of the XS energy drinks.

  • Mango Pineapple Guava 
  • Cranberry-Grape Blast

So, if you want, you can also opt for the caffeine-free version of this energy drink to be on the safe side.

Celsius Energy Drink

Sugar: 0g

Caffeine: 200mg – 300mg

Calories: 10

The next incredible energy drink on our list is Celsius energy drink. This energy drink is completely sugar-free and has only ten calories. Furthermore, this energy drink has 200-300 mg of caffeine, which is moderate. So, if you need an extra boost during your intermittent fasting, then this energy drink is perfect for you.

Celsius Energy Drink comes in various flavors.

Furthermore, Celsius also has three different flavors, which are:

  • Celsius Heat (300mg caffeine per can)
  • Originals (200mg caffeine per can)
  • Naturals (200mg caffeine per can)

So, you can choose any of these energy drink flavors according to your needs. However, remember that consuming caffeine in moderate amounts is better when intermittent fasting. And, since this energy drink has almost half of the daily recommended amount, it is better to stay within limits and only have one can in a day.

Bang Energy Drink

Bang energy drink is an incredible energy drink that will keep you energized for long hours.

Sugar: 0g

Caffeine: 300mg

Calories: 0

The last energy drink on our list of best for intermittent fasting is Bang energy drink. Like the other two energy drinks, it has zero sugar in its formula. Moreover, it is completely calorie-free.

The only problem with this energy drink is that it has 300mg of caffeine which, in my opinion, is too much. However, if you can handle this much caffeine in a day, you can have this energy drink. But, do remember to consume it in moderate amounts as it has almost exceeded the daily recommended amount of caffeine in a day and can cause side effects if you consume more than one can in a day.

Also, this energy drink has BCCAs in it, which means you can consume it as your pre-workout energy drink. However, there is a lawsuit regarding the misleading information about this energy drink. Therefore, please do your research before consuming it.
