Is VG fattening?

[LoveMeTender]

I'm trying to cut down on sugar products I intake so I can lose some weight, will the sugars in VG be absorbed by my system and make me fatter?

My assumption is that because inhaled substances don't go through the digestive process, where they are broken down and utilized for energy, you are not actually absorbing calories through the process (otherwise, we'd see some rather large fry cooks at McD's). But, when you inhale vaporized glycerin, whatever tiny portion hits your lungs has to go somewhere. I'm no pulmonologist, nor do I play one on TV.

If you're worried about it, let's assume for the moment that you could even get caloric energy from vaporized vegetable glycerin.

Glycerin has 4.32 calories per gram. VG (also known as glycerol) has a density of ~1.13 grams per ml (converting from this site).
If you consumed an average of 3 ml of 100% VG a day, you'd only add about 15 calories to your intake per day.
That's about the number of calories in, say, a teaspoon of sugar. It will have no measurable effect on weight gain or loss.
(Again, I'm making these calculations as if you ate it, not vaped it, for reassurance's sake.)

So in terms of any post-quitting weight gain (which some have dealt with during vaping, some have not -- there are threads discussing this, of course), VG will not be the culprit.

I'm not a doctor either, but nicotine speeds up the metabolism so maybe it's a wash. They might know in the health section of this forum. Have you had a look there?
