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:

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. 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.

A small soft drink will keep you out of ketosis for a day, the large ones for more like a week…


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

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…

    As a home brewer of Kombucha, how does one measure the carb content of the finished product. The end product is very much weather / climate dependent, so a 8 day Summer brew may take 15 days in Winter. Any ideas?

    Ist this really true?

    The small soft drinks will keep you out of ketosis for a day, the large ones for more like a week…

    How long time (days) does it take for a person that does eat carbs to go in to ketosis? (When you start a new diet whit low carb)

    I would be very interested in the answer to your kombucha question, and also if one can measure the carb content of water kefir drinks too. It seems they may be good for probiotics, but bad for carbs.

    can i use coconut milk in my coffee? and other drinks rather than butter or cream as I prefer the taste?

    I found it frustrating to home brew Kombucha because I was waiting so long for the sugar to be utilized by the yeast that I was afraid it had gone too far! I found a great product by Clearly Kombucha Raspberry Lemonade which unlike EVERY other commercial Kombucha only had 2 gr of carbs (sugars) per 16 oz bottle. Their other flavors are higher, and it's impossible to find in SoCal, so I am watching this thread with bated ketone-y breath!

    Hi... I too brew Kombucha at home as the store bought ones are expensive and have a higher sugar content. I was led to believe that home brewed Kombucha was lower in carbs. I too drink it for the pro biotics. I would be interested in an answer to these questions.

    So glad I come across this. Now I have someone to talk to about csrbd. I started the diet about a month ago. Lost a little. Started craving sugar so bad. I felt like an addict. I ate so much candy. Soon the weight plus more is back on. I didn't know whether to do my weight watchers or the shepherd diet. which is. 20 carbs a day and Half YOUR BODY WEIGHT IN PROTEIN THE REST HEALTHY fats.

    Where do I find the carb count for yogurt? I make my own using 3.8% milk. And culture it for 24 hours.
    Overall, this is a great website with terrific information. Thanks for putting it together.

    Is there any harm with me adding almond milk-unsweetened to my coffee in morning, Only two carbs for 8 oz, and I use maybe 4. I just started the two week kept challenge, but only like coffee with almond milk added. I really want to have the coffee for a couple reasons. Thanks!! (Well, I'd also like to add a few drops of stevia, if that won't thwart my efforts too. I'm not a sugar addict, but it makes the coffee more palatable.).

    How many carbs are in a glass of unsweetened iced tea? Everything I find online says 0, or less than 2, but you have it at 32. Is this with sugar in it?

    Hi Angie!

    Personally I think in resonable amount unsweetened almond milk is OK. But it's easy to over-consume when you drink calories. It also has a bit unfavorable omega 3 : omega 6 ratio. But using it in coffee instead of milk that I would say is a good choice.

    Milk is generally too high carb for keto. You can find our top keto guide here which includes food to eat and food to avoid.
