You have come to the right place that's for sure!! I felt like you, that I was ALWAYS going to be fat, but I can tell you, from coming here for support and coming every single day to log my food....I am well on the way to my goal, and 18 months ago I would never ever have said I would have been.
I had tried every single diet on the market, but ya know what...? LC works!!
Give it your best shot, and it does take time to change the habits of a lifetime, but LC WILL make you thin.
Good luck!!
