Following a ketogenic approach may put some people off after they hear the stories of the dreaded “keto breath”.

Keto breath has a “distinctive smell” to say the least, both for you and those close by.

Those who have experienced keto breath describe it as being a metallic taste in their mouths. In addition to the odd taste, experienced ketoers have mentioned that keto breath can be fruity-smelling or smell somewhat similar to nail polish remover.

The metabolic process of ketosis produces beta hydroxybutyrate, acetoacetate, and acetone. Acetone is the same compound found in some nail polish remover products which explains the strange, metallic smell / taste of “keto breath”.

While undesirable, occurrence of the breath is a great indicator that you’re entering into a ketogenic state and starting to use fat as your primary source of fuel!

Now the obvious quick fix would be more carbohydrate in your diet, but that kind of defeats the point of this whole keto campaign in the first place, right?

Well, enter; keto friendly chewing gum!

Can You Chew Gum on Keto?

Why of course you can! In fact, you should if you’re training to manage any onset of keto breath!

People believe gum is off the table as it’s typically associated with being sugar sweetened. Over consumption of sugar sweetened foods on a keto diet runs the risk of knocking you out of ketosis, however all the brands we’ve suggested our totally sugar free!

The other reason people may be hesitant on keto gum is to do with the sweeteners it contains. There is no evidence to suggest that sweeteners have any significant effect on our blood sugar / insulin levels that would cause you to lose a ketogenic state!

In terms of health concerns, sweeteners, both artificial and naturally occurring, have been deemed safe for consumption by the FDA.

While most sugar free gums contain the artificial sweetener aspartame, these chewing gums which we’ve suggested contain a naturally occurring sweetener called xylitol (found in many fruits and vegetables).

In contrast to common belief regarding sweetener consumption, xylitol may actually confer a number of health benefits when regularly consumed!

Can You Chew Gum on a Fast?

You can most definitely chew gum on a fast!

The mechanisms of a fast involve an absence of food for a prolonged period of time resulting in the use of internal stores of energy; namely fat in this instance!

Insulin inhibits the actions of certain enzymes which break down fats to be used as energy. Carbohydrate intake, more accurately, easily to digest sugars, will raise our own blood sugars which will then raise insulin levels (insulin signals to a cell to take in circulating glucose for energy or storage).

This is where our gum comes in; most store-bought gums, as we mentioned, do contain many added sugars. Over consumption can spike blood glucose which can in turn elevate insulin and not only knock us out of a fast but even possibly knock us out of ketosis!

We’d advise keeping an eye on the sugar content of your store-bought chewing gums and going with one of our recommend brands; keto AND fast friendly and just as, if not tastier, than their alternatives!

What to Look for in a Keto Friendly Gum?

First and foremost, you want to ensure that your chosen gum isn’t masquerading as something it shouldn’t be and claiming to be “keto friendly” while having a bunch of added sugars thrown in.

A good indicator of this is if the gum is calorie free or at least five calories or less per serving.

The second primary consideration for any keto dieter is the sweetener used in the gum. If and when we can, we should aim to stick to “natural” sweeteners over their artificial alternatives.

They appear to have some benefit to health over their artificial counterparts which, if over-consumed, have been linked to certain negative outcomes.


We alluded to the sweetener content of our recommended chewing gums earlier; xylitol, a natural sweetener.

Studies have shown that xylitol has negligible effects on blood sugar and insulin levels, making it a perfect choice for keto and or fasting style dieters.

Xylitol has only one tenth of the glycaemic index score of sugar (the index scoring certain foods on how quickly they change blood sugar levels) and 40% of the energy content of sugar.
