My Rheumatologist told me, that a small percentage of individuals were able to send their AutoImmune diseases into complete remission by loosing all excess body fat and staying there. She said that fat creates a pro inflammatory environment that directly effects the progress of diseases like Rheumatoid Arthritis. The key is very very low body fat, how you look to other people is irrelevant.
The math is starting at 200lbs 30%bf, with 130lbs lean mass. Subtract 23%bf =-46lbs. 200lbs - 46fat =154lbs at 7%bf
I may even try to go down to 6%bf temporarily if it means resetting my raging immune system. For a man, only 6-7% body fat is required to make hormones and basic body functions. Anything below 6% on a man is considered counterproductive. I use to body build and train in boxing when I was in my 20s. I knew competitive male athletes that would temporarily go down to 4%bf for competition. They did not stay there long, but they said their health was fine as long as it was only temporary.
