Can You Vape On Keto?

The holy grail of any keto dieter is getting their metabolism into ketosis. Ketosis is the metabolic state of processing fats instead of glucose (carbs) as its primary fuel source. 

After a time of being in ketosis, your body will become fat adapted, and this is when the body has switched to burning fat for fuel as its default.

Several ‘vapers’ have reached out to see whether the sweetness in vaping is going to cause a spike in blood sugar levels.

What is in Vape Juice?

Most vape juices contain only four main ingredients;

  • Water
  • Nicotine
  • Flavorings

Does Vape Juice Have Carbs?

Vegetable glycerin is a sugar alcohol that gives the vapor its sweet flavor. Propylene Glycol is also an alcohol and works in a very similar way to Vegetable Glycerin. 

Both Propylene Glycol and Vegetable Glycerin work similarly to erythritol or xylitol, both sugar alcohols that are low on the Glycaemic Index (GI).

Recoding low on the GI means that these sugars will not spike your blood sugar levels and therefore not knock you out of ketosis. Propylene Glycol and Vegetable Glycerin work similarly.
