I’ve never heard of that theory… but I think some people get a bit fundamentalist with fasting.
I haven’t noticed any issues with either sugar free drinks or sweet vape flavours. And I’ve lost a ridiculous amount of weight in 3 months. I no longer fit any of my old pants and belts and got hit on for the first time in a decade.
(Sorry, that’s the best measurement I have, I haven’t been weighing or find any pre-IF photos to show my progress)
I have no clue about if a sweet vape can create insulin spike, but if your goal is weight loss IF, then it could still work for you.
Artificial sweeteners may trigger insulin response for some people. Personally I can only say that I’ve been using artificial sweeteners in my fasting hours too, and I continued to shed weight and never got hungry either because of them. I might just be lucky, and admittedly I had no way to actually measure my insulin levels.
It suppose it can be different from individual to individual with sweeteners, so it might be a similar thing with vape.
It sure is an interesting question though.
Thanks for the response. I’m surprised you drink sugar free drinks, but I guess I’ve never really looked into the science behind IF. Infer that their calorie free but I aways assumed that they would somehow stop your body from fasting.
Different people react differently to insulin triggers, but for me, vaping has absolutely no noticeable effect on blood glucose, so it’s unlikely it has any meaningful effect on insulin.
The nicotine vapor (and additives) are inhaled into the lungs, not the stomach, so it enters the body directly into the bloodstream from the lungs. It is not metabolized via the liver, so I doubt it should have any effect, either.
