As far as your husband hoping this isn't just some "fad" thing, does it help him to know that this "fad" has been around for 30 years and has steadily improved upon itself through case histories and studies and that all those who jump on the bandwagon know that when they have jumped off they feel terrible -- physically -- and that returning to this WOE makes a real difference in quality of life?

My favorite saying for instances like yours is, "To each his own." It makes sense and it's the God's honest truth!

As everyone here has already said, he's seeing positive changes and as long as that is present he'll come around. He may be worried for your long-term health, but in a few months get some bloodwork done, be still fibromyalgia-free and moving around like your old self ... and he won't need much more convincing.

Keep at it!
