On a keto diet, you can enjoy a variety of drinks as long as they do not contain carbs or have minimal amounts. Coffee and tea without sugar are excellent choices, and they can be enriched with heavy cream or unsweetened plant-based milks such as almond or coconut milk. Plain sparkling water is also suitable and can be a refreshing option. The main thing is to avoid sweetened and fruit juices, as well as regular milk due to its high carbohydrate content.
