Weight loss plan. Could this plan work permanently?

If you want to follow the weight watchers plan, thats fine, but I don't think its nessessary. You should just eat between 1000-1200 calories a day and that would be sufficient. And it won't kill your metabolism. Just dont go lower than 1000. Also, Alli is the over the counter for a prescription med. Alli is half the strength, so if you want to get the full strength you could go to the doctor and ask them for it. You'll pay just as much, but for full strength. Good luck.
