Most energy drinks are packed with sugar. In fact, some popular drinks have more sugar than regular soda. That’s why it’s always important to check the label on your drink before you take a sip.

1. Total carbs

The most important thing to consider when picking a keto friendly energy drink is the carb count. Regular energy drinks can pack a ton of carbs, but the best energy drinks for a low carb diet should be 5 or less grams of carbs.

Stick with low-carb (5 grams or less per serving) drinks to ensure you don’t go over your carb count each day.

2. Sugars

Another important nutrition stat to look at before drinking your energy drink is the amount of sugar per serving.

Sugar free drinks are the best option because they’ll help you stay in ketosis and won’t add to your daily carb count.

3. Calories

While the number of calories in your drink won’t directly affect ketosis while on a keto diet, it is an important factor to consider with weight loss.

A lower number of calories is a great way to ensure you aren’t drinking too many calories as you consume your energy drink.

4. Sweeteners

Sugar free drinks typically use artificial or natural sweeteners to flavor their drinks without the need for sugar. And while most calorie-free sugar alternatives are keto-friendly, some are linked with harmful health side effects. That’s why it’s a good idea to consider the type of sugar free sweetener used in your energy drink.

Check the ingredient list on the back of your can to see what type of sweetener is used in your drink of choice.

  1. Are there options without sugar alcohol? I have been experiencing bloating and gas pain which I read can be contributed to sugar alcohol, but love having sparkling water, energy drinks and the occasional diet coke. Any suggestions?
