I cannot imagine why people have so much trouble losing weight, when you have made it all so simple for them./sarc
Well... i mean he's not wrong. It's the simple truth.
I've personally gone up and down like a jo-jo mainly due smoking / qutting smoking. Every time i quit, i ended up eating more because i could actually taste how good stuff actually were.
I used smoking as a suppresant I could easily regulate how / what / how much i ate when i smoked because that would dampen the hunger feelings i had.
That said, once i started vaping i pretty much gained +10 because everything started to taste so delicous!! I WANTED IT ALL.
But then i started to be real with my self, and start to regulate my in / out. Easy as that i was dropping in wieght.
Not saying it was easy, but... just i cant find a more proper word for it.
I'm still slightly overwieght and working on my last few kgs. But all in all, i can't say vaping helped me at all there. If anything it was the opposite. But that's because i was a former smoker, who now could start to smell and taste all the goodies. (and the bad

)
But yea somehow vaping does not help me in the same way smoking did. Now it's pure willpower and planning.
