My metabolism is nill due to lazy bowels from lazatives. Is there anyone out there who has found a diet that eases constipation and helps with weight loss? Or better yet - is there anyone out there who has had a successfull surgery using any of the "barrier" products. Or has anyone gone to another country and had success? There was a website for some surgery center in Germany but I can't find it again. Any help will be appreciated. If I can help . . .Thanks!
