13. Unsweetened Coffee and Tea
Both coffee and tea are carb-free beverages that are suitable for a ketogenic lifestyle. Caffeine can boost metabolism and improve alertness, physical performance, and overall mood. Drinking tea and coffee in moderation can even help lower the risk of diabetes. Avoid sweet flavorings, which contain a lot of carbohydrates. Some heavy cream is okay, but any light variations probably use non-fat milk.
