Low carb drinks – the best and the worst

What do you drink on low carb? 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.

Check out this visual guide for more good options, and what to definitely avoid. Just remember, what you add to your drink is just as important as the drink itself!

Low-carb drinks

The numbers represent grams of net carbs per normal serving size (like what you get if you order one in a restaurant).1 The green numbers represent decent options on low carb. Drinks with asterisks have some special caveats. Keep reading for more details below.

Add a sugar cube to your coffee or tea, and you add 4 grams of carbs (not good).

Size mattersSize does matter

While sugary soda is always a bad idea on low carb, size matters. A large soft drink contains truly astonishing amounts of sugar with 159 grams in this example.

A small soft drink can keep you out of ketosis for a day, but the large ones could effect you for much longer, possibly an entire week!2


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 can maintain sugar cravings, a potential disaster if you’re addicted to sweet foods.3 They can 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).4

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


Low-Carb AlcoholLow carb alcoholic drinks

What are the best low carb alcoholic drinks? Beer, wine or something else?

Here’s the short answer: Wine is good, beer is usually not. However, there’s something else with no carbs at all. Spirits like vodka, whiskey and tequila have no net carbs. That doesn’t mean they have no calories, but when it comes to carb counting they are good options.
