That was a really good article on the surgeries cariad, thank you for posting it. I know a few people who have had the band done, and both have lost a lot of weight and had few complications. That being said, after reading those stories I don't think I'd ever consider it for myself.
devlinswife, you obviously use the computer, have you looked into myfitnesspal.com? They have a calorie tracker. I am always giving a half assed effort to lose weight (still 50lbs more than I was pre-baby and he's 3 now, and 65lbs more than I was before I donated my kidney) but I think a lot of my issues are genetic. I did lose 20lbs rather easily over the summer before hubby had his most recent transplant by simply tracking what I was eating on that site. They also have an app you can download for free to a droid or iphone. I know it seems silly, but seriously seeing how much you consume, or how many calories are in what you are eating (despite thinking it's a better choice) can be really astonishing. The app for the phone even has a barcode scanner so you can scan the product you are eating, and then you put in the quantity. It also keeps track of your exercise so you can see how many extra calories you burn by talking the stairs, or walking around the block in the evening.
Also, I know with PD you have less diet restrictions, have you asked your PD dietitian about meal replacement shakes? Like slim fast type stuff? Maybe she knows of something safe for D patients?
Aside from exercise, the only other advise I can offer is to eat lots of fiber. Fiber will make you feel fuller longer, so fruits like raspberries, apples and pears are high fiber per serving as are green peas. But the catch for D patients (and I am still going through this while trying to diet while hubby is on HD) is that you have to eat a lot of empty carbs, like bleached grains. Whole grains are high in fiber and less processed so they have more nutritional value, while processed grains like white rice, white bread get broken down some during processing, so they lose a lot of their benefits. And I refuse to buy 2 things of bread, 2 types of rice etc.
Good luck, and I mean that. I really think surgery should be a last resort option. I said I know people who had great success (though one recently had to have a revision on her band because she couldn't keep down food), but after reading that article the horror stories and risks seem way more dangerous than I ever imagined.
