Chiming is as an outsider ...
I read the book a very long time ago. Probably have forgotten more than I ever knew

However ...
I've been hanging around with a wide variety of dieters and losers for many years now and here's what I've observed with regard to any any reduced carb plan.
A lot of folks don't really "get" the basic macronutrients. "Right, what's a protein?"
A lot of folks don't realise how many carbs they do eat that have absolutely no nutritional value. In fact they probably don't know how many carbs they eat at all ... what a huge percentage of their total intake.
I don't understand the difference between reduced carb and low carb etc. How low is low? Is it relative? In which case most calorie counters are probably low carbing it?
Too many people simply imagine their foodlife as it is but without carbs (or what they imagine carbs to be). Ya know? patty, no bun. steak, no fries. slice o'bologna, no bread.
Many, many, many of us would have a chicken breast with a lovely salad, yet deny low carbing.
Yer basic fella off the street it woefully lacking in nutrition ed., sadly. There's waaaay too much bad information from waaaay too many bad sources. A dreadful, harmful combination.
