I was wondering about whether I should get a lap band(If I'm eligible) as I'm about twice my healthy weight, and I have type 2 diabetes, and I was wondering if it was possible on a mainly vegan diet. Anyone know?
Part of the problem, I think, is getting enough protein.
It can be done. However, I would strongly urge you to really go on a low-fat vegan diet (like that promoted in Forks Over Knives and the PCRM's 21-Day Weight Loss Kickstart.
I have had my Lap-Band for 6 years and I am incredibly sorry that I ever did this. It can work. For most people it does. But not everyone manages to hit the "sweet spot" where the balance between the band being "too loose" (can overeat) and "too tight" (can't eat without pain or vomiting).
Also, the Lap-Band is very dependent on good long-term follow up care. If you move to a new city/state you may have a very hard time finding a Lap-Band surgeon who is willing to take on a patient for whom they did not perform the surgery. I moved from Florida to Alabama and I have been unable to find a doc to do my aftercare. It has been horrible.
At my heaviest I weighed about 320. I lost about 50 pounds directly related to the Lap-Band. Today I weighed in at 237. But the pounds between 270 and 237 were lost the "old fashioned" way. By watching my food intake, by paying attention to what kind of foods I am eating, by limiting high-fat, high-calorie, nutrient-deficient foods.
Even with the Lap-Band in optimal working order you will still need to do the work. You still need to pay attention to what you're eating, when you're eating it, and how you eat it. A lifetime of "tiny bites" and having to chew your food excessively in order to avoid things getting stuck in the stoma, the pain when you mess it up and get something stuck, the vomiting ... For me I really don't think that it was worth it.
I heard someone call the Lap-Band, "Surgically Induced Bulemia." While there may be some hyperbole in that statement, it isn't really all that far off the mark.
My honest opinion from the BTDT side of the fence - If you can't follow the diets outlined by Dr. Neal Barnard, Dr. Ornish, or Dr. McDougall on your own and make those healthier food choices without the Lap-Band you're unlikely to do it with the Lap-Band. The truth of the matter is that you can (and many people do) eat around the band. When you're tight (or too tight) you can eat mashed potatoes with butter and sour cream, creamy soups, milkshakes, ice cream ... all high-fat, low nutrition density foods.
Perhaps my Lap-Band has been instrumental in keeping off the first 50 pounds that I lost. But it hasn't been instrumental in losing any additional weight since that initial loss, which included my week long liquid diet and the 6 weeks of post-op diet. The 6 weeks of post-op dieting included 2 weeks of clear liquids only, then 2 weeks of thicker liquids (think protein shakes), then 2 weeks of blended soups and such, before moving to soft foods and then finally on to solid foods. I think anyone eating like that would have lost the same amount of weight, with or without the Lap-Band.
