Extreme obesity

Maybe about 250-300 pounds. I want to stay mobile but I want to get very big, especially on my belly thighs and ass

Maybe even more, thinking up to 400 lb

250-300 pounds would be my goal as of now. I would like to stay decently mobile but still fat. I wouldn’t mind if I was bigger then that but I’m not actively trying to get any bigger then that right now

My current goal is 350-450lbs. I know people have talked about the challenges and setbacks of larger sizes, but my life is specifically built in a way that enables a good living experience at higher weights given I work from home/bed in my own time, I have good access to everything I need, I don't have particularly major needs or responsibilities beyond my work.

I know for a fact I absolutely want to hit a minimum of 350lbs and there's a specific, calculated reason for that, but I'd definitely prefer to reach the 400s
