Vince, if your doctor truly told you that then I sincerely hope they are better at diagnosing illness than they are at estimating bodyfat percentage. According to this calculator you started with a BMI of 41 which puts you in the severly obese category. Since you have stated that you were laid up and unable to do much excercise for a period of 7 months, I seriously doubt that your lean body mass is high enough to remove you from that category.
