I don't bother with all that dieting $#%^ but I reckon you should only lose weight for health reasons and most certainly never for anyone else.
If you're a larger lady now and you wanna become a skinny lady then you need to accept that this is very likely not going to happen but if you take a few small steps in the direction of eating healthily then you probably will shed a few pounds, you'll feel so much more better and what's more you'll look sexy as ###$.
Best wishes.
