Nicotine, smoking or vaping do not cause weight gain nor loss. Eating or not eating does. People gain weight sometimes when they quit smoking because they eat to satisfy what they're missing orally by not smoking. People keep weight off by smoking instead of eating for the same oral reason. Same goes for vaping with the exception that some people are so satisfied with the food/dessert flavors themselves instead of just the oral satisfaction that they don't eat as much. For instance, some who never smoked vape as a diet aid. They vape cheesecake flavor instead of eating cheesecake. However, some who vape food flavors then want the real thing more and, thus, eat more and gain weight vaping. None of the above has anything to do with nicotine and just as easily happens vaping zero nic. Nicotine does the same thing caffeine does so if that makes you extra active and you don't eat to compensate for the extra activity, you'll loose weight but again it all comes down to eating... not smoking nor vaping. Besides who wants to be strung out and jittery from that much caffeine?
