Finding a Bariatric Nutritionist
Look for a registered dietician, not a nutritionist. A RD has college degree in nutrition and is licensed by the state, while a nutritionist does not have to have a degree (some might but it's not required) and they are not regulated in any way.
You can look for registered dieticians on the website of the Academy of Nutrition and Dietetics: http://www.eatright.org/iframe/findrd.aspx
Please note: I AM NOT A DOCTOR. If you want medical advice, talk to your doctor. Whatever I post, there is probably some surgeon or other health care provider somewhere that disagrees with me. If you want to know what your surgeon thinks, then ask him or her. Check out my blog.
Thanks, Poet Kelly, You are so knowledgeable, and my fill doctor was Dr. Kelly, and I sometimes just want to call YOU Dr. Kelly. I sure have learned a lot on this forum, especially from all the vets and you. I really do appreciate your input. I know we all must ask the same questions over and over again, but it is so comforting to know you are all so non-judgmental and helpful!
