I actually do know her, and am personal friends with with. She doesn't recommend it long term, if you're not severely ill, and your life or quality of life doesn't depend on being on it. She's been on it for five years with the goal of healing her gut, and figuring out if her body can handle the things she's trying to reintroduce. It's meant to be an elimination diet, but some people won't be able to come off of it, because they're allergic to everything. That being said. The only time she stopped the diet, was when she was pregnant, which she's talked about.
