Your version is a little low on the drinking calories in my opinion. I was skinny as a rail until my wife and I got together when I was 23 and started going to reverse happy hour at TGIFridays, Applebees, etc pretty much every night. Add drinking roughly another six pack most nights after the reverse happy hour along with smoking weed + more munchies and I never had a chance no matter how much exercise I did. I probably put on around 30-40 lbs in my first year of that lifestyle.
