Is Coke Zero Keto?

No, not really. Coke zero is not keto suitable, since there are sweeteners included in a Coke Zero, which causes a blood sugar spike. You might want to reduce your consumption of Coke Zero to once or twice a week.

Zero Sugar Softdrinks and Keto Diet

Since carbohydrates in ketosis are usually reduced to less than 50 g and blood sugar spikes should be avoided as much as possible, sugar-containing soft drinks do not fit into ketogenic everyday life in any case.

Theoretically, zero drinks containing aspartame could be integrated into a ketogenic diet, as they neither influence the blood sugar level nor contain unnecessary carbohydrates. However, as regular consumption of aspartame is suspected to be associated with countless negative effects, this can only be advised against.

But do not worry! Calorie-free soft drinks can also be enjoyed from time to time in a ketogenic diet. The Green Coke sweetened with Stevia has no bad influence on ketosis and also has positive properties. Lowering blood sugar and blood pressure, the sweetener, unlike aspartame, can actually be an enrichment for everyday life.

Meanwhile there are sugar-free variants. That sounds good at first sight.

But caution is called for! The so-called zero drinks, i.e. almost calorie-free versions of the original version, unfortunately also have a catch. Although the problem with the massive sugar content has been solved, there is now another one. This is called aspartame, an artificial sweetener.

Aspartame has no calories and is therefore often used for sweetening instead of household sugar. Although it is produced synthetically, it still tastes ‘natural’ like sugar. However, regular and high consumption could have devastating consequences. Aspartame is associated with countless unwanted side effects, including

  • Osteoarthritis,
  • Migraine,
  • Hair loss,
  • Dizzy spells
  • and much more.

In addition, the all too popular sweetener is suspected of being carcinogenic due to its chemical structure. This potential danger has also already been addressed in studies and should urgently be investigated further.

The solution?

What is new now is to sweeten soft drinks with steviol glycosides instead of aspartame. One example is Green Cola, which already exists in a few different flavours. Steviol glycosides or stevia come from the so-called stevia plant, making it a naturally occurring sweetener.

The sweetening power of Stevia is about 30 times stronger than that of regular sugar. Studies have shown that the plant has a blood pressure-lowering effect. It is also considered to lower blood sugar levels and can therefore have a positive effect on our health. The only disadvantage would be a slight taste of its own, which is nevertheless quite different from that of sugar.

Now you have to weigh up for yourself what is more important to you: your health or the original taste of cola. However, since the flavour changes only slightly with Stevia as a substitute, this should be of little importance to most people. When it comes to health, Stevia clearly outperforms sugar, as well as apsartame.

The only thing you should always keep in mind, however, is that soft drinks can contain some additives, such as colorants. That’s why you should still consume these drinks in moderation and not necessarily make them an everyday ritual.


In conclusion, it can be said that soft drinks have so far been regarded as rather bad for health. However, this could take a turn with Stevia as a sweetener. The plant is gaining popularity and for good reason. So even during ketosis it is okay to resort to drinks like Green Cola, which you can also find in our KetoUp-Shop.
