I find myself here wishing this thread wasn't so old. Could use the encouragement, haha. So, here's the scoop: I have a BMI of 82 and at 24yrs old I weigh 511lbs. My doctor at NWWLS in Everett, WA (Dr. Michaelson) has put me on the typical pre-surgery diet, only its 60 days instead of the typical 7-14 days. Im to do 3-4 awful protein drinks a day and one solid Lean Cuisine type meal a day. My final prep appointment is May 10th and can pretty much do surgery anytime once I've lost 60 pounds...So technically I may not have to hold out the entire 60 days. Have any of you had to do this pre-op? Even if it wasn't as long, how much was lost in your time spent doing it? I realize its very individual, but from your experience could someone my size be able to lose 60 pounds in less than 60 days?? :/
