Hi, to anyone I just want to post a theory I have. I started vaping again about a month ago and my weight has shot up 10 lbs. I suspect it is because the flavoring chemicals in the ecigs cause my body to release insulin which in turn drops my blood sugar which in turn makes me ravenous, especially for carbs and junk food. These cravings are surprising because I've been Low Carb High Fat Keto for over a year now, and doing great, but this vaping has killed me. Thankfully I intermittent fast as well which is very helpful, but I've been eating all kinds of carbs and I can't talk myself out of it when the urge comes. They use flavorings that when eaten I'm sure cause an insulin response so I believe it happens from inhalation as well. As such I've stopped vaping a few days ago, and the cravings are waning. I am determined to not smoke cigarettes anymore. I hope I can make this work. I just wanted to alert anyone experiencing similar symptoms of hunger and weight gain seemingly brought on by vaping that it may be the insulin. Insulin is a driver of weight gain and heart disease. Good luck to us all to stay away from cigarettes first and foremost. Further luck with the rest. Be well yall.
