From what I see... There are no pics of her wheels.. or her back etc. And this is My opinion. I don't find overly skinny women attractive. I like curves and muscle.
Losing "weight" isn't what I would do but thats what she asked. I'd Kick ass training hard and try to put on more muscle. I don't think this is what Courtney wants. My ideal body and hers I am sure are completely different.
Unless she plans on competing I can't understand why she would need to drop that much weight.
I am by no means trying to stroke her self esteem... If I thought she needed to lose 20lbs etc I'd have said it. I would want people to be honest with me therefore I do the same. I think she has a very nice body... 20lbs of loss would make her really thin and IMO that isn't attractive.
