Every single legitimately disabled person would love to have an easy solution (like eating less) to fix their disability.  Not even that, difficulty eating just comes along as a side effect to many serious medical issues. Fat people are too lazy or weak willed to handle what amounts to a single side effect of many legitimate medical problems. Difficulty keeping food down is pretty common with cancer for example. And it's not even brought up all that much because feeling hungry is just such a minor thing compared to what it feels like to have your body essentially eating you alive.  Most people I've known who have cancer are compassionate to a fault. To the point where they wouldn't want it to happen. But I really do wish that fat people had to walk into a hospital every now and then and announce to everyone getting chemo/immunotherapy/radiation/etc how hard it is to just reduce their caloric intake a bit.
