I have that book as well since it's an easier reference list to take to the grocery store than the book.
I am frequently running out of my house 15 minutes after getting out of bed, and the other day I ran out of the quiche egg cups, and was desperate to get some food into me, so I stopped at Wal-mart. (I was good!

) Anyway, my thought was to grab some celery or something because they sell these little packs of celery that are ready to eat. Unfortunately for me, the SBD craze is hitting hard out here & there was no celery to be found... ANYWHERE in the store, string cheese either, so I pulled out my nifty little book to see if I could have anything like a slimfast bar, etc.
If you read the little blurb before they list the bars and shakes, Dr.A talks about how these certainly aren't a good idea for a regular thing, but when the circumstances dictate, they''re better than fast food. So I took my little book over to the aisle with the shakes & bars & stuff. The slimfast for a low carb lifestyle is the one that's acceptable in the book, (I had to read all the labels) so I bought a 4-pack. It certainly wasn't great, but it did the trick for the 3 hours I was out running around, and it didn't seem to trigger any cravings for me.
Now that I've rambled on for 3 days, I'll say what I wanted to say in the first place:

For an emergency situation thay're good, but that's about it.
