Is anon a neet who contributes fuck all to the household? Does anon go days without washing? Has anon been caught rummaging around in Stacy's underwear drawer?
You're not wrong. Eating just 500 extra calories a day (which is like two donuts, something I could pop down without even realizing I'd done it) means you'll put on a pound a week (3500 calories = 1 pound of body fat) or 52 pounds in one year, which would take a 6'0" 180-pound man into obese territory, per BMI calculations. And TBF that's pretty weak sauce; on numerous occasions I've added that much fat just over the Winter.
