Question: are diet drinks allowed on keto?
Answer: Can you drink soda on the Keto Diet? No, but diet soda is OK on keto in moderation. Unsurprisingly, regular soft drinks are out, as a single 12-ounce can of Pepsi has 41 grams of carbohydrates. If you want to satisfy your soda craving, you'll have to opt for diet sodas, which use artificial sweeteners.
