Fats have definitely ruined alcohol for me, even slightly chubbier people have ruined alcohol for me too. They don't seem to understand that you can eat clean all week but you can ruin it with one night of drinking. Plus people outright not understanding how many calories are in drinks, I used to think vodka was relatively 'clean' only to discover how blatantly calorific it is. But they can take pizza from my cold dead hands, every few months I'll get a large Dominos pizza at 10am and slowly eat it throughout the day (sometimes leaving a good chunk for the next day) and I feel disgusted that people can legit eat this much pizza in a single sitting.
