Fwiw, I lost about 4 kg of my average weight (That was about 7% of my body weight) when I stopped smoking. A couple of years down the road I also quit drinking which also decreased my average weight by another 4 kg.
(With average weight I take into consideration that I have natural, not dieting related fluctuations of about +/- 1 to 2 kg. The fluctuations are still there but the mean they deviate from is vastly different.)
Maybe I should add that I am still eating about five pounds of sugar a day and I haven’t done sports since 2012, so don’t assume that quitting smoking meant a healthier lifestyle (sadly).
I’m not sure what country you are from, but as someone whose vote literally is counted before I even see a ballot, let me tell you, please vote or at least do something. If you don’t like the way politics in your country work, go out and demonstrate. Take it to the streets. Talk to your neighbors, make leaflets. But please don’t just go bitter and sit in your corner because everything is shit anyways. Because this is how we ended up with a lot of the messes we are having now. I “voted” for the first time this year in a rigged election and before that I also always thought the way you do. Democracy is dead, why bother, my vote doesn’t count anyway. But once I stood in this fucking line and smuggled in a non erasable pen and voted and went out knowing no one will even look at this ballot something changed.
