The Best Low Carb Drinks (and Ones To Avoid)

For people who choose a low-carb way of eating, it can be quite difficult to know what you can eat and drink at first.

This is particularly true for drinks, and sometimes it is surprising how much carbohydrate and sugar drinks can contain.

This article provides a guide to some of the best low-carb and keto drink options besides water.

Various Different Hot and Cold Drinks.

Best Low Carb Drinks

The drinks in this section each offer very low amounts of carbohydrates.

As such, they are suitable for regular consumption by anyone on a low-carb or ketogenic diet.

For each drink, you can see the total amount of carbohydrates per 100 ml unless otherwise indicated.

All nutrition data is sourced from the USDA Food Composition Database.

1) Almond Milk (Unsweetened)

Amount (grams per 100 ml)
Carbohydrate 0.8 g
Fiber 0.4 g
Sugars
“Net carbs” 0.4 g

Almond milk comes in many varieties, many of which are full of fillers and additives such as sugar.

However, if you opt for unsweetened almond milk, then the carb count is minimal.

Almond milk also offers a decent source of several nutrients, particularly copper, magnesium, manganese, and vitamin E.

It’s also worth noting that it is easy to make almond milk at home; all you have to do is blend almonds and water until you have a creamy, consistent liquid.

To do this, use two cups of water for every half a cup of almonds. You can also try using slightly less or slightly more after the first time, depending on your preferred thickness.

2) Black Coffee

Amount (grams per 100 ml)
Carbohydrate 0 g
Fiber
Sugars
“Net carbs” 0 g

Coffee does not contain any appreciable amount of carbohydrates, and it’s a healthy and delicious drink.

On that note, large systematic reviews even suggest that moderate coffee consumption may have several health benefits and lower the risk of mortality (1, 2, 3).

3) Black Tea

Amount (grams per 100 ml)
Carbohydrate 0.0 g
Fiber
Sugars
“Net carbs” 0.0 g

Black tea is another calorie-free option.

Similar to coffee, there are lots of studies investigating the potential health benefits of black tea.

Among the research, studies suggest the drink may have slight immune modulating and blood pressure benefits (4, 5).

4) Cashew Milk (Unsweetened)

Amount (grams per 100 ml)
Carbohydrate 1.0 g
Fiber
Sugars
“Net carbs” 1.0 g

Cashew milk is another creamy nut-based drink that offers a good source of protein and various minerals.

It is also possible to make it at home in the same way as almond milk.

5) Champagne

Amount (grams per 100 ml)
Carbohydrate 3.0 g
Fiber
Sugars 3.0 g
“Net carbs” 3 g

For those who like the occasional drink (or to celebrate), then Champagne can be a reasonably low-carb drink.

Per 100 ml, it only contains around three grams.

However, make sure to opt for dry Champagne, as sweet versions can be quite high in carbs.

See this full guide to low-carb alcohol to see how all the different drinks compare.

6) Cocoa (2 tbsp)

Amount (grams per cup)
Carbohydrate 6.0 g
Fiber 3.4 g
Sugars 0.2 g
“Net carbs” 2.6 g

Love chocolate?

Many people do, but you won’t find low amounts of carbs in most of the commercial hot chocolate options.

However, if you make your own hot chocolate at home, unsweetened cocoa keeps the carbs very low.

Add a bit of heavy cream (or milk of choice) and use a low-calorie sweetener to make it taste the way you want it.

7) Coconut Milk

Amount (grams per 100 ml)
Carbohydrate 5.5 g
Fiber 2.2 g
Sugars 3.3 g
“Net carbs” 3.3 g

Coconut milk is a thick and creamy drink made by grating the flesh of fresh coconut and adding small amounts of water.

While it is very low in carbs, watch out for the fat and overall calorie content – drinking regular cups of this is an easy way to gain a few pounds!

8) Diet Soda

Amount (grams per 100 ml)
Carbohydrate 0 g
Fiber
Sugars
“Net carbs” 0 g

Diet soda—such as Diet Coke and Pepsi Max—has a mixed reputation, with many people harboring suspicions about artificial sweeteners such as aspartame.

However, large-scale systematic reviews and clinical trials on these products fail to prove any adverse health effects at realistic human doses (6, 7).

Unlike regular cola and soft drinks in general, these diet drinks contain zero grams of carbohydrate (the regular sugar versions have around 10 grams per 100 ml).

9) Green Tea

Amount (grams per 100 ml)
Carbohydrate 0.0 g
Fiber
Sugars
“Net carbs” 0.0 g

Green tea is extremely popular throughout many East Asian countries and is particularly prevalent in China and Japan.

This tea also has a lot of research behind it, and it is widely regarded as one of the healthiest things to drink.

Green tea comes in a wide range of varieties, and some of the most famous include Genmaicha, Matcha, and Sencha.

Like most types of tea, this one contains no calories and no carbs.

10) Hemp Milk (unsweetened)

Amount (grams per 100 ml)
Carbohydrate 0.5 g
Fiber 0.2
Sugars Trace
“Net carbs” 0.3 g

Hemp milk is similar in appearance to almond and cashew milk.

However, this drink comes from seeds rather than nuts, and it is even lower in carbohydrate.

Despite coming from seeds, hemp milk tastes slightly nutty, and it has a thick and creamy consistency.

11) Herbal Tea (most varieties)

Amount (grams per 100 ml)
Carbohydrate 0 g
Fiber
Sugars
“Net carbs” 0 g

Otherwise known as “tisanes,” there are all kinds of different herbal tea options.

On the positive side, most of them offer a carb-free, healthy and refreshing drink.

That said, watch out for sweet powdered versions of these teas, as these can be quite high in simple sugars.

All in all, there are thousands of herbal tea options to try, but some of the most popular include;

  • Chamomile
  • Hibiscus
  • Lavender
  • Lemongrass
  • Peppermint
  • Rooibos
  • Rosehip
  • Spearmint
  • Valerian

12) Homemade Smoothies (see recipe)

Amount (grams per 100 ml)
Carbohydrate 4.7 g
Fiber 2.2 g
Sugars 2.3 g
“Net carbs” 2.4 g

The amount of sugar can easily add up in store-bought juice drinks and smoothies.

However, it is possible to make low-carb smoothies at home using ingredients like berries and coconut milk.

For example, the following recipe (for two people) contains only 2.4 grams of net carbs per 100 ml;

  • 1 cup (240 ml) coconut milk
  • 1 cup (240 ml) water
  • ¾ cup raspberries
  • 3 drops of pure vanilla essence

13) Lemon Tea (Or Lemon Water)

Amount (per drink)
Carbohydrate 2.1 g
Fiber 0.6 g
Sugars 0.6 g
“Net carbs” 1.5 g

Do you prefer to drink water, but find it a little plain tasting?

Well, it is easy to freshen it up a bit with a little lemon. All you have to do is add a few slices to your cold (or hot) water.

That said, don’t expect too much in the way of health benefits.

Lemon water appears to be trending these days, and it is easy to come across stories on the “amazing benefits of lemon water”.

But it is just water with a tiny piece of lemon in it.

All in all, lemon tea or water will provide about 1.5 g net carbs per drink (if you actually eat the lemon).

14) Light Beer

Amount (per drink)
Carbohydrate 1.6 g – 7.0 g
Fiber
Sugars
“Net carbs” 1.6 g – 7.0 g

While it is probably better to avoid regular beer, there are a variety of light beer options that are reasonably low in carbs (and calories).

Although the taste isn’t as good as the real thing, light beer can be a convenient option for those who don’t want to give up beer altogether.

See this full guide to low carb beer options for more information.

15) Protein Shakes (Whey Isolate)

Amount (per drink)
Carbohydrate 0.8 g
Fiber
Sugars
“Net carbs” 0.8 g

They won’t ever be as tasty as eating a steak or other real food options, but protein shakes can be a convenient on-the-go protein source.

Since they are almost 100% protein, they are very low in dietary carbohydrate too.

A typical protein shake made from one scoop (around one ounce) of whey protein isolate offers less than a gram of carbs.

16) Red Wine (Dry)

Amount (per 100 ml)
Carbohydrate 2.6 g
Fiber
Sugars 0.6 g
“Net carbs” 2.6 g

For those who enjoy wine, a glass of red can be compatible with a low carb diet – but it is better to stick to a dry wine.

Per 100 ml, such wine offers around 2.6 grams of carbohydrate (3.8 grams per 5 oz or 150 ml glass).

However, every single variety of wine slightly differs in carb content. You can find out the exact details in this low carb wine guide.

17) Sparkling Water

Amount (per 100 ml)
Carbohydrate 0 g
Fiber
Sugars
“Net carbs” 0 g

Sparkling water is a great choice if you’re looking for a more exciting version of water.

Since it is the same as regular tap water nutritionally, sparkling water contains no carbs or calories.

However, you could try adding some berries or slices of lemon to make a healthier version of a fruit soda.

18) Spirits

Amount (per 100 ml)
Carbohydrate 0 g
Fiber
Sugars
“Net carbs” 0 g

Spirits like rum, vodka, and whiskey contain no carbs.

By combining these with diet sodas, you could also make calorie and carb-free versions of rum and coke or vodka and lemonade.

However, it is worth remembering that our body prioritizes the metabolization of alcohol over all other macronutrients.

In other words, drinking slows our overall metabolism (8).

19) White Wine

Amount (per 100 ml)
Carbohydrate 2.6 g
Fiber
Sugars 0.6
“Net carbs” 2.6 g

White wine shares a similar nutrient profile to red wine.

Once more, providing it is dry red wine, it is a low-carb friendly drink.

20) Water

Amount (per 100 ml)
Carbohydrate 0 g
Fiber
Sugars
“Net carbs” 0 g

Don’t forget about pure water; it is cheap/free, easily accessible, and one of the healthiest things you can drink.

Moderate-Carb Drinks

A Frothy Milky Cup of Hot Latte.

In this next section, the drinks contain moderate amounts of carbohydrate.

As a result, anyone on a strict low-carb diet might want to moderate their intake of these options.

1) Beer

Amount (per 100 ml)
Carbohydrate 3.6 g
Fiber
Sugars
“Net carbs” 3.6 g

Regular beer may look quite low in carbs at (on average) 3.6 grams per 100 ml.

However, when you look at how much beer the average person drinks, these numbers can add up.

While a “beer belly” isn’t only down to alcohol, binging on it can certainly contribute.

Beer is not very low-carb friendly, but for anyone who wants to drink it, moderation is necessary.

2) Latte

Amount (per 100 ml)
Carbohydrate 4.6 g
Fiber
Sugars 4.6 g
“Net carbs” 4.6 g

While black coffee is virtually calorie free, a latte is basically coffee-flavored milk.

With nearly as much carbohydrate content as regular milk, it is still possible to enjoy a latte on a low-carb diet.

However, it should be in moderation, as the carb count can quickly add up with regular consumption.

3) Coconut Water (Unsweetened)

Amount (per 100 ml)
Carbohydrate 3.7 g
Fiber
Sugars 1.1 g
“Net carbs” 2.6 g

Almost all coconut products have become trendy over the past decade or so, and coconut water is no exception.

With just short of four grams of carbohydrate per 100 ml, it is a moderate-carb option to limit.

4) Milk

Amount (per 100 ml)
Carbohydrate 4.7 g
Fiber
Sugars 4.7 g
“Net carbs” 4.7 g

Milk is a fairly nutritious drink, and it is a great source of calcium and protein.

However, with nearly five grams of carbohydrate per 100 ml, these numbers can get high quickly with regular milk consumption.

A small glass or two a day is fine if that’s what people want, but it should be carefully worked into their dietary aims.

5) Kombucha

Amount (per 100 ml)
Carbohydrate 2 g – 8 g
Fiber
Sugars 2 g – 8 g
“Net carbs” 2 g – 8 g

Kombucha is a popular fermented black or green tea drink often flavored with fruit juice.

While some kombucha is reasonably low-carb, other options can be very high in sugar – some even add extra sugar for a sweet taste.

Label checking and a moderate intake may be necessary for this one.

Low Carb Drinks To Avoid

Various Bottles and Cans of Cola and Soda.

The following drinks all vary in their carbohydrate content, but they contain too much sugar to be suitable for a low-carb diet.

  • Alcopops/Malternatives/Spirit Coolers: these options are basically alcoholic soft drinks, and they are full of sugar.
  • Cola and Other Soft Drinks: the nutrient profile varies by brand, but soft drinks generally contain around 10 grams of sugar per 100 ml.
  • Cocktails: full of fruit juice and/or sugar.
  • Craft Beer: Drinks like IPA and craft beers in general are all carb-heavy, and they may also be flavored or even sweetened with added sugar.
  • Fruit Juice: Drinks like apple and orange juice contain as much sugar per 100 ml as cola. If you feel like fruit, eating a piece of whole fruit is a better idea.
  • Sports drinks: These ‘hydrating’ drinks marketed toward athletes often contain large amounts of sugar – as much as cola in some cases.

Final Thoughts

As shown in this guide, there are plenty of healthy and delicious drinks that are suitable for a low-carb diet.

Additionally, the drinks in the ‘moderate’ and ‘avoid’ sections can still be worked into the diet, as it is the total carb intake that matters most.

However, don’t forget to track liquid calories/carbs if you’re drinking them, as they can quickly add up.
