Ya, not buying that stat at all. I could believe 99% or even 99.9%, but there's always going to be shitlords. It's already a massive advantage being one in today's world of obeasts (living longer, automatically more attractive than 80% of people, higher wages, etc.), if it got to the point where almost everyone was an obeast, some opportunistic people would certainly maintain a healthy weight just to reap the benefits of being a "god among men."
