Chocolate on a low-carb diet – oh yes, you can!


Unsweetened cocoaMost people think of chocolate as the ultimate enemy of a diet. I see many tweets from people who recently went low-carb, declaring desperate cravings for chocolate and great sadness at not being able to have any.

Actually, it doesn’t have to be this way.

Chocolate’s reputation suffered because of the sugar that usually gets added to cocoa – but you can always use sweetener instead of sugar.

Chocolate in itself is not the problem – the added sugar is

Pure 100% unsweetened cocoa is quite high in fat, but not that high in carbs – net carb content is between 10-20 net carbs per 100g, depending on the brand.

Bear in mind that this count is for the most concentrated possible form of chocolate – far too rich and bitter to have on its own, so typically you would mix it in recipes with something else – usually some form of dairy, like fresh cream or butter (there are hundreds of other possibilities). By then, net carb count would be diluted further. There are many recipes for chocolate-rich treats at about 2-4g nets carbs per serving.

So what exactly is cocoa?

Cocoa is extracted from seeds of Theobroma cacao tree. Seeds are roasted and shelled, resulting in cocoa nibs. Nibs are then ground into a paste, which is known as chocolate liquor and is used as a basis for chocolate products, or separated into cocoa butter and cocoa solids.

Natural cocoa contains a high level of flavonoids, specifically epicatechin, which has been found to have benefitial effects on cardiovascular health. [i]

Cocoa is sometimes treated with an alkalising agent (“Dutch-processing”) to give it a milder taste, as natural 100% cocoa is quite bitter. Unfortunately, Dutch processing also strips out most of the antioxidants. Watch out when using Dutch-processed cocoa in baking – use baking powder rather than baking soda as the leavening agent.

Where can I get unsweetened cocoa?

The two widely available types of unsweetened cocoa are blocks of 100% cocoa solids, and cocoa powders.  I normally use the following UK brands:

Willie’s Cacao for natural, organic solid blocks of chocolate
Buy 100% cacao sugar-free chocolate

Green & Black for organic Dutch-processed powder
Buy sugar-free cocoa powder

So what can you do with all this cocoa while on a low-carb diet?

You can do lots!

Low-carb friendly chocolate bars and truffles

Simply mix the cocoa with fresh cream (about 2 parts of chocolate to 1-3 parts of cream, depending on the desired consistency) and your sweetener of choice to create chocolate treats. Check out my dark chocolate truffles recipe.

Chocolate creams and mousses

Whip up a bit of cocoa and sweetener with some dairy like cream, butter or sour cream. Also try adding eggs, coconut milk or even mashed avocado. Use about 1 cup of your main ingredient to 1-2 tbsp of cocoa powder.

Gluten-free baking

Add chocolate to gluten-free cakes and biscuits to create wonderfully rich desserts. Check out my recipes for gluten-free, sugar-free chocolate cake and chocolate biscuits.

Is cocoa allowed on all types of low-carb diets?

Atkins – unsweetened cocoa powder is allowed in all phases including Induction

Dukan – reduced-fat cocoa powder is allowed in all phases including Attack

Paleo – depends on the specific system you are following, some consider cocoa to be too processed to count as a natural food (especially Dutch-processed products).

Ready-made chocolate products

Cavalier chocolate range uses Stevia instead of sugar, and so would be suitable for low-carb dieters. Buy Cavalier dark chocolate

Atkins Advantage range includes solid chocolate bars and bars with different fillings.

  1. I’m from Spain and here all low carb diets have been dragged into the spotlight by the National Board of Nutritionists and Dietitians: they say all low-carb diets are unbalanced and dangerous for your health, accusing their followers of fanaticism and sectarianism. Criticism has been targeted most of all to the Dukan diet, to the point that Paleo and Atkins blogs are also treating dukan dieters as stupid morons that are risking their health to a fad diet. It’s refreshing to read blogs as yours, where Dukan diet is treated as just another option and not as the incarnation of all evil.

    1. Hi Maria, I agree with you completely. Lowcarb diets get bad press here in the UK as well. It is usually obvious from the articles that their authors know very little about the subject, they just have a knee-jerk reaction “lowcarb = bad”.

      Thank you for your comment and I hope you will keep reading my blog.

  2. I love that chocolate is actually good for diets! Thanks for posting this info and the recipes! I’m definitely going to try the dark chocolate truffles to top my Atkins-approved cheesecake!
