Diet Dr. Pepper

Diet Dr. Pepper has zero carbs. That makes it an ideal choice when you want to enjoy the taste of soda without breaking your ketosis.

One of the biggest challenges of a keto diet is staying properly hydrated. It's fine to mix in a bit of soda for taste, but the best way to hydrate is by drinking plenty of water.


The primary sweetener in Diet Dr. Pepper is aspartame, a sweetener that has attracted more controversy in the last twenty years than almost any other food product. A 2006 animal study initially launched the debate over aspartame, as it suggested that aspartame increases the risk of cancer. That study was widely panned, and subsequent analyses, including one by the European Food Safety Authority (EFSA), found no link between cancer and normal aspartame consumption.

A small number of people have found that aspartame can interfere with their ketosis. If you're not sure whether your body reacts negatively to aspartame, experiment with Diet Dr. Pepper in small portions before integrating it into your normal diet.


For a soda without artificial sweeteners, consider Zevia. It's sweetened with stevia, a natural, keto-friendly sweetener that does not increase blood sugar.

You can also create your own keto-friendly soda at home. Devices like Sodastream or the Hamilton Beach Fizzini make it possible to create your own keto sodas while controlling every ingredient you use.
