Most people enjoy an occasional energy drink even while on the ketogenic diet. One of the world’s most popular energy drinks is RedBull. However, the name isn’t synonymous with a healthy drink. The company has come up with a sugar-free energy drinks variety for its health-conscious customers.

Both of these ingredients are artificial sweeteners linked with increased appetite resulting in weight gain.

On a traditional keto diet also known as clean keto, this drink is not recommended since the artificial sweeteners are not keto-friendly.
