Update

Sorry I haven't posted for awhile, but by the time you finish reading this, you'll know why.
Racket Guy and I are now following the same eating plan together, and I just have to say, I'm speechless.
He lost 4 pounds in 10 days, and it was really a hassle because his pants wouldn't stay up.  It took us a long time to find the belt that he had worn 10 years ago, since it was buried in the pile of stuff that we just threw into the closet right before the holiday guests arrived last winter.
After a few days on my plan, he thought he was going to die. He almost did, from the immediate kidney failure.  I called the ambulance and they rushed him to the hospital.  This was really a hassle because I had to find someone to take care of the cats and to feed the snails.
While we were at the medical center starting dialysis we found out he had contracted osteoporosis during his short stint on the diet.
While they did additional testing, they found that he had a high level of 3-hydroxybutyric acid, so they decided to admit him to the hospital.  (So that's why we missed the latest episode of Glee, sorry folks!  They didn't have a working television in the waiting room by ICU.)
In the morning, his doctor visited, and told him that he had incurred a fair amount of bone loss during the 10 days on the diet. We looked at some of the x-rays and I was shocked to discover that his right femur was completely missing.  Now all this time, I had thought that the reason that he collapsed was from dehydration.  Since I heard that the weight people lose on such a diet is just from water, I just made that connection.  It never occurred to me that the dramatic weight loss was NOT due to water alone.  The doctor did explain that while he was not dehydrated, he would regain the 4 pounds of water weight he lost and then some if he just went off that disastrous diet.
He felt a bit better after eating a bit of the hospital food.  They brought a bowl of maple oatmeal with skim milk, a container of Jello, a cup of juice and some apple slices.
I guess that is what I should be feeding him now, until he regains enough strength to feed himself.  I need to go to the grocery store to pick up a few items on his food list:  quinoa, oatmeal, skim milk, applesauce, fat-free soy margarine and a bunch of containers of Ms. Anorexic Bovine ice cream. 
He was feeling a bit weak this afternoon, and I wanted to give him a shake of potassium in his seitan salad, but when I called the cardiologist for permission, they said she had already left for the day.  Probably out golfing, gee, just when we need her.
Thank you all for your support and prayers during these trying times.  It is about time for us to get honest with ourselves, to listen to our bodies, and to pay attention to the experts.  If we had just taken the advice of the experts, none of these disasters would have happened.
