The part that is especially funny is they think thin people survive off nothing.  Two almonds and a slice of air. So they'd rather "enjoy" their food.  I made a 9x13 pan of brownies the other day knowing nobody would be eating them but me.  I ate some over a few days and stayed under my maintenance calories because I needed to cut back after a restaurant visit.  There is no all or nothing.  I go out to eat, I have treats, I exercise if I want to.  I choose.  I don't have to live off kale and run on the treadmill 3 hours a day.  But that's what they think, because they're defeatists.  They don't want to try so they pretend it's impossible.
