I too am on the six month supervised diet. For me I'm learning to make healthier choices, and I'm trying to train my mind to stop eating when I'm satisfied, and to say no to my favorite fatning foods or to not consume so much of it. This has also been a good time for me to get use to a good Protein drink, and to start a small exercise plan. I own an elipticle but could only do five minuets at first now I'm up to fifteen minutes. I do count calories, and my doctor told me to try to stay at 1200 calories. I've been used to eating over 2000 calories a day so that seemed hard so I just cut down to 1800 calories at first, then worked down to 1500 calories and now I'm between 1200 and 1300 calories. I just think this is the time to get your mind in the right place to face the hunger and craving issues, to find foods that you can live with eating, and to work on finding the right exercise plan that you can live with. Take it slow and work your way to find what works best for you and your lifestyle. I'm learning to cook healthier and choose healthier foods at the grocery, although healthier foods are so much more expensive.
My doctor told me those who are sucessful in their efforts before surgery will more likely to be successful after surgery because you're already conditioning your mind, and your habits, and the lapband takes hard work and dedication that we will already be use too. At first I was like " I dont want to lose a lot of weight because I didnt want to be ineligable for surgery" but as I read other posts it only helps you later and the insurance goes by your starting weight which for me was 282. I've lost seven pounds in two weeks. I'm only a month in the diet but it took me two weeks to get my mind right, but once I did it has been good so far. Best luck to you!
