2-weeks out today

Well today is 2 weeks post-op kinda discouraged because I have only lost 5lbs since surgery. I get in between 50-60 protein daily, 64oz of fluid and I am walking almost 2 miles a day, I started working out at curves yesterday to see if that will help. I get in 450-700 cal a day. I really hope my nightmare isn't coming true that I had this surgery and still can't lose weight I don't see how that caould be because of cal I take in a hellalot less then be surgery. It will get better I know it will in time!!!!!
