Ahhh I have to reply. Former loser, right here!
She's doing this to fulfill a void in her life. She's probably extremely depressed about being obese...so she's living in a fantasy world. What she wants to happen is to lose 80lbs. and have women praise her...so that's what she's creating. In a fantasy world would we have to deal with loose skin and stretch marks? Nope! So that's why she "doesn't have any".
My mom died I was 13...and I went a little loopy. I was depressed and desperate for attention. So I used to get online and lie about my mother. I'd talk about how great we get along, how much fun we had together, how much she loved me. I made our relationship online better than the one we actually had! And of course...I'd put down other girls moms. "I wish your mom was like mine...she's so awesome!" Kind of what your friend is doing...she's creating a perfect fantasy world and I was creating a perfect fantasy mom.
Please don't be angry with her. I know that can be a first reaction because she's making light of what we on here are working so hard to do...but she's obviously not well. There's something very wrong with her and I can relate in a way. You should feel a lot more pity than anger, even though I'm sure it's really hard.
And everyone should ease up a little on judging her. Yeah it's wrong...but I'm sure we've all done things that were wrong. Especially those of us who have struggled.
