I doubt it. I've never been overweight in my lifetime. I have never had to put any effort into that. I simply cannot relate at all to the food-related struggles I sometimes read about overweight people having. It would be silly and condescending of me to claim that I simply have more strength of will here than they do. On the other hand, I struggle heavily with some things many/most people do not, and this is often blamed as a personal failure and weakness of mine. So I wonder if it's just that people who don't have any similar struggles think they are just superior beings with superior willpower.
