I imagine WW could be useful in that you have a "plan" and support from the meetings. The 5 day pouch test is just a fad diet. Period.
First and foremost, DO NOT feel shame because you had a regain. The potential is there for EVERYONE to regain-if we do not alter our lifestyle FOREVER. Please see your surgeon to ensure your plumbing is in tact and in good order. Once you know that all is well on the insides, then you have to find a way to get your head in the game. It really is simple-burn more calories than you consume and you will lose weight. I said SIMPLE-NOT EASY. You must find ways to move your body. Then you have to find dense protein foods that will keep you full. One of the guaranteed ways to regain weight is to drink with meals. You need to stop this immediately. Also, wait at least 1 hour after you eat before you start drinking.
I recommend the following:
1) Begin tracking everything you put into your mouth. You can do that here on OH in the Health Tracker or on Myfitnesspal.com.
2) Determine your RMR http://www.caloriesperhour.com/index_burn.php
3) Set your daily caloric level at your RMR - 500. This will set you up to lose 1 lb per week, which is the safest level to shoot for AND it will give you enough food so you don't feel deprived.
4) Make 100-120 grams of protein per day your goal. I eat a 6-7 oz grilled chicken breast every single day. That alone is 53 grams of protein, and it is real food so I feel full.
5) Eat 6-7 small meals each day. This will keep your blood sugar level and will keep you feeling full. DO NOT DRINK WITH MEALS AND WAIT 1 HOUR AFTER A MEAL TO RESUME DRINKING.
6) Exercise. Everyday. At least 30 minutes. If your heartrate is up and you are sweating, you are good.
7) Follow the rules of your surgery. Do not drink with meals and do not drink for at least 30-60 minutes afterward. Limit simple carbs and sugar, but don't completely eliminate them. If you do, you'll feel deprived, and we all know how well that has worked for us in the past.......
