Hi, Tigra....glad you found us over here in the corner!
Your experiences are not that different from what many of us have had, so you're in good company indeed.
As to the abbreviations....well, only two of them are Hellers' inventions, namely CM (Complementary Meal) and RM (Reward Meal) The CM is the 1 to 3 meals per day you may eat that contain no carbohydrate-rich foods. The RM is the one meals per day that you must eat that can contain anything your little heart desires. Purty good, huh?
As to that "BM", well, that's just an abbreviation for an ordinary body function we should all do once a day....."bowel movement".
Not surprisingly, if one does not do this regularly, one's weight tends to creep up a bit.....anyway, back to your adventure w/ CAD.....
There are several very experienced folks on this forum, and each of them will be able to help you out as you need it....just ask. That's all ya gotta do.
If you want to, while you are waiting for your book to arrive, you might try staying on Atkins Induction and limiting your intake of foods greater than about 4 g carbs/serving to only one meal per day. At the rest of your meals, eat proteins and LC veggies...anything that gives you 4 g carbs per serving or less. That'll be good practice for when you get started on CAD, if you'd like to do that. Or you can wait until you've read your book completely and have a good understanding of the science behind the plan.
For a good explanation of the science, see above where Zuleikaa explains the insulin release during eating and why the RM must be limited to one hour. She's right on about it, and this is the central piece of the Hellers' plan. No matter which book of theirs you are following, they did not stray from this original concept. Once you get that down, you've got it!
The "cup" serving is a standard measuring cup....in the US it's 8 fluid ounces.
Again, welcome...we're glad you came!
