I'm seriously considering it, at least as an experiment. I have type 1 diabetes, so I'm constantly trying to figure out how much insulin to take -- and I don't always get it right. This is mostly a matter of judging the food I'm consuming, but not completely; there's also endocrine issues which affect blood glucose levels (usually pushing them up), and exercise usually pulls blood glucose levels down.

I think having a "standard diet" which takes food out of the picture would make it much easier to figure out how all the other pieces fit together.
