WTF!

All i can say to you is don't compare yourself to anyone else. Everyone is different and yes the bigger you are when u start the faster you lose. I started at 551 pounds at 5'10 and two weeks out of surgery  (rny) i lost 50 pounds. I am 4 years out of gastric and i am 50 pounds from my goal weight of 230 pounds. Don't be too hard on yourself it isnt easy what you are doing .
