In a lot of ways, I understand where Carlos Romero is coming from. It is hard to tell someone you recently lost a lot of weight. Weight loss does not solve a lot of body image issues. You have to deal with loose skin and stretch marks when you drop an excessive amount of weight. I would venture to say it is harder for women dating as well.
The girl Carlos sees now did say that she would probably have passed on him at his old 400 pound self. They have things in common now including rock climbing.
