Billy,
Why should you lose weight? You shouldn't! Despite all the positives that folks experience for themselves, it is because there are things they want that you don't. One thing I am very sure of, despite all the rewards for me, losing weight is hard, any change is. The positives only come after some negatives. (I find my food tastes changing, but before they did I really really missed the things I used to like. I don't miss them much now, but it took time for me to prefer other options.)
One thing I am very sure of, losing weight for someone else doesn't work. You don't want to lose weight. Don't. Your family can't make you have surgery. At most they can nag you, and of course to the extent you depend on them they can refuse to assist. I hope you are as honest with them as you are here. Don't play games about metabolism, tell your brother you don't want to lose weight.
I find it sad and amusing simultaneously that so many folks here want to convince you that you should lose and how wonderful it will be. Weightloss (or maintenance) is a personal choice. It may be awful for you. We complain about the judgements of others, I don't need affirmation about why losing weight would be good, I want to lose it. If you don't, okay.
I know the statistics are grim, I've been one of them for a long time. I hope and believe that I have changed things enough for me to be one of the 2% this time. If I am, it is because I have made some radical changes in my thinking and behavior. No one could make those changes for me, and no one could force me to make those changes.
Apparently you are pleased with your life and choices...so be it.
Others here are far more kind and tolerant. Me, not so much. This group is weight loss support. You seem to want to rename it "no weight loss support." You are completely entitled to do what you want, but 3FC is not about weight acceptance or promotion of being fat.


Imagine what you could do if you did try!

- I didn't just lose the weight & keep it off. This is my SIXTH attempt. I have lost & gained 30-40 pounds five times before... now my goal is to lose 45-50 pounds. I can only hope that I learn something THIS GO ROUND that I didn't learn before - and that is to maintain the loss once I finally lose it. Because honestly, I think yo-yo-dieting is just as bad for you as not dieting at all.
