Keto drinks – the best and the worst

What do you drink on a keto diet? What are the best options, and the most common mistakes?

The quick answer: Water is perfect and zero carb, as is coffee and tea (without sugar, of course). The occasional glass of wine is fine too.

Low-Carb Diet DrinksDiet soft drinks – are artificial sweeteners OK or not?

Diet soft drinks come without carbs or calories. Instead, they contain artificial sweeteners like aspartame, sucralose, acesulfame K or stevia.

Many people believe diet drinks are safe, as they are free from calories. However, it’s not that simple, and these non-caloric sweeteners come with their own set of problems.

To start with, these sweeteners maintain sugar cravings, a disaster if you’re addicted to sweet foods. They make it harder to appreciate the natural sweetness of real food. Also, studies show that switching from diet soda to water results in weight loss, perhaps as some diet drinks can increase insulin levels (thus increasing fat storage).2

In short, diet drinks are probably less bad than regular sugary soda. But if you can wean yourself off the sweet drinks completely and enjoy water, that’s by far the best option. Learn more
