Following a ketogenic diet can be challenging, especially when it comes to finding suitable beverages that align with your low-carb lifestyle.

However, seltzer water can be a great alternative, providing a refreshing and bubbly experience without derailing your ketosis.

Understanding the Keto Diet

Before diving into the best seltzer options for keto, let’s briefly recap what the ketogenic diet entails.

To achieve ketosis, you need to limit your carbohydrate intake to around 20-50 grams per day, depending on your individual needs and goals.
