My friend is overweight and I can say she is very insecure about her body. I will try to convince them to get weight loss surgery, but I do not want to appear mean or that I only care about their weight. I am not attracted to thin size 2 type girl, but I am for girls with curves kinda like Jordin Sparks attracted size. How do I talk with my friend about getting weight loss surgery or just lose weight the old fashion way, without them feel bad?
