Maybe TomS knows the answer to this?
 
I have mentioned before that I have had Gastric Bypass surgery. It has been 15 months since my surgery and I have lost 87% of my surgeons goal. By my calculations I have lost 93%. Both my family doctor and surgeon have pronounced me a success story. Now the only thing I am really dealing with is the extra skin. As of this moment I am leaning towards leaving it as it is not as severe as many gastric patients I have seen. My question is, since the excess skin that I am now carrying could weigh as much as 10-15 pounds (I think I am closer to the 10, maybe even under), how should I read BMI numbers? Since it is a weight based calculation should I subtract 10 pounds before calculating or leave my weight unadjusted? I don't think I have this issue with resistive body fat percentage as that is not weight based. Of course it is harder to take accurate caliper measurements with the excess skin.

The reason I ask is that at my height and current weight I am still considered very heavy with a BMI of 30.3, of course this is down from a high of 49.6 on January 1, 2006. When I do the resistive body fat measurement it comes out about 23%. Should I be concerned or should I adjust.

Still applies to the BMI numbers, as it is mass on the body. It skews the lean muscle mass ratio as well, because it is still excess tissue that isn't muscle. The long term effect though is negligible, so it's not a worry (other than vanity) unless you start developing excoriations under the "apron". These can lead to chronic infections and becomes a comorbidity that places the plastic surgery under the medical necessity category. (Just a though for future reference!:D )
