Is Red Bull Sugar Free Keto Friendly?

Answer: One can of Red Bull Sugar Free contains 8.4 oz. of fluid. One of these cans only contains 1.8 grams of net carbs, which actually makes it a keto-friendly energy drink.

But how healthy are sugar-free drinks really?

All over the internet there are different opinions about low-calorie and sugar-free food. Sugar-free beverages in particular are very important in this respect. If you don’t always want to quench your thirst with tasteless drinks, you might want to try cola or fruit juice. However, since these are not always advantageous, especially in a weight-reducing lifestyle, the sugar-free variant is increasingly preferred as an alternative for calorie-reduced sweetening. In particular, energy drinks are increasingly used as a coffee substitute in everyday life.

If one compares the nutritional values of the energy drink “Red Bull”, for example, with those of its sugar-free version “Red Bull Sugarfree”, serious differences can be seen: For example, a 250ml can of the classic Red Bull has a total of 112.5 kcal, 27.5 g carbohydrates and 27.5 g sugar, while the sugar-free alternative has only 7.5 kcal, 0 g carbohydrates and 0 g sugar.

Reason enough for someone who is looking for a low-calorie diet to opt for the light variant instead of the calorie bomb. Is it?

But what exactly does “sugar-free” mean?

The substances contained in these drinks, on the one hand sweeteners such as aspartame and on the other hand sugar substitutes such as erythritol, have been summarised under the term “sweetener” since December 2014.

These are synthetically produced or natural compounds which are used to sweeten foods. Compared to normal household sugar, they taste many times sweeter and contain almost no calories.

But how healthy can something developed by chemical processes be?

Sugar-free drinks and diseases: According to the FDA, there are currently no conclusive studies that prove a connection between the consumption of sugar-free products and the development of diseases. However, there are more and more articles or contributions appearing on the internet which cast doubt on these findings.


A study conducted by Israeli researchers in 2014 found that various sweeteners increase the risk of diabetes by altering the intestinal flora and ultimately disrupting glucose metabolism. This disorder in turn ultimately represents a risk factor for diabetes.

Furthermore, studies report on a cancer-promoting effect of sweeteners. However, these statements cannot currently be confirmed by the American Cancer Information Centre. The American Cancer Information Centre is of the opinion that additives should only be approved after careful examination and should continue to be subject to strict and regular review. According to the current state of affairs, it can therefore be assumed that they are harmless and not carcinogenic.

Sugar-free drinks and ravenous appetite

Unfortunately, there is currently no clear evidence that sugar-free drinks cause ravenous appetite attacks or not. However, some of the publications published so far assume a connection between these two factors.

When sugary foods are consumed, the blood sugar level in the body increases. This means that the concentration of sugar in the blood is significantly increased. Insulin is secreted in order to transport the sugar from the blood into the cells and provide energy. This process causes the blood sugar curve to drop again, resulting in a feeling of hunger. How much the blood sugar curve rises and falls depends on the proportion of carbohydrates or sugar in the food. The higher this is, the more the curve rises and the faster it falls again. The consequence of this is ravenous appetite.

According to some studies, if sugar-free foods are consumed, insulin is also released. However, the difference is that this is not usable energy. The reason why insulin is released despite the lack of sugar could be due to the sweet taste. This deceives the brain, which has the same effect as with sugary foods. As a result, the blood sugar curve also drops, which is reflected in attacks of ravenous appetite. The process is therefore the same, with the difference that no calories are absorbed and therefore no energy can be converted.


How excessive consumption of artificially produced substances actually affects the body in the long term and whether it is absolutely necessary to consume them on a daily basis is nevertheless questionable. If you want to induce a harmless and healthy fluid intake, you should rather resort to still water, unsweetened tea or thin fruit juice spritzers.

Nevertheless, at this point it should be said…

The dose makes the poison! If you don’t want to completely do without the sweet taste of a refreshing cola, you should take a glass of Diet Cola every now and then. Because compared to the 8 cubes of sugar contained in a glass (0.2l) of classic cola, this is always the more sensible option.
