Nutrition Facts About Diet Coke

Below you will find the most important nutrition facts about Diet Coke. This information is also relevant for Coca-Cola Zero. The table shows only the most relevant data and facts that are especially interesting and useful in the context of a keto diet.

Nutrition Facts Of Diet Coke

Diet Coke has almost no calories, no carbs and no sugar. But is it really a good choice?

Diet Coke & Its Keto Compliance (9/10)

Here you will find information and facts about how keto compliant Diet Coke is.

A Diet Coke is a keto friendly product because it has practically no calories, no carbs and no sugar. Its glycemic index (GI) is 0.

Some studies show that diet and zero drinks can still cause an insulin spike because of their sweet taste. However, most people agree that Diet Coke causes almost no metabolic response.

That’s why we can say that Diet Coke is technically OK for a keto diet. However, the biggest concern is with its possible adverse effects on health.

Diet Coke On A Ketogenic Diet & Health Impact (2/10)

Here you will find information and facts about how healthy Diet Coke is.

Both Diet Coke and Coca-Cola Zero have no calories, no carbs and don’t spike insulin. However, they both taste very sweet and that’s thanks to the artificial sweeteners they contain (aspartame or/and acesulfame potassium).  

The long-term effects of aspartame are not fully known. Current research on aspartame shows rather conflicting results (depending on who sponsored the research). Acesulfame potassium seems to be less evil but it still can be harmful in huge amounts (above 1g).

However, most people agree that Diet Coke or Coca-Cola Zero are not healthy in the long run and it’s not only because of the artificial sweeteners they contain but also their negative impact on stomach and the gut. After all, the full list of Coca-Cola ingredients is kept secret.

Bottom Line: Avoid If Possible

Whenever you’re about to grab a can of Diet Coke or Coca-Cola Zero, you have to choose between your diet (staying in ketosis) and your health (not poisoning yourself with artificial sweeteners).

Of course, nothing will happen if you drink a can of Diet Coke once in a while to avoid drinking a sugary beverage at a party. However, drinking it regularly as a replacement for sweetened drinks is a very bad idea.

Remember that a keto diet is about health. It’s not about chasing ketones and maintaining ketosis at all costs (even at the cost of your health).
