Firstly, Thank you for your input. Secondly, I specifically stated that by cutting out HFCS from your diet, you are effectively also removing a large quantity of junk food from your diet as well. I am well aware of how I lost weight, and that I was in fact grossly overweight (275 at 6'1"). However, I hardly consider my "methods" to be "arcane" as I simply cleaned up my diet, monitored my caloric intake, specifically where those calories were coming from, and hit the gym with a single-minded purpose. I am fairly certain most people on this site who have made a concerted effort to lose weight and succeeded will agree that those are pretty much standard weight-loss fare.
My frustration comes more from the fact that the girl in question feels a need to tear down my accomplishments in order to validate her own lifestyle (one which I have myself forsaken). I understand that this will be very common in my life for as long as I continue to train hard and respect my body, but since this is still new to me, I am not yet accustomed to having people rain on my one man parade.
