There are a couple of things that I'd like to point out -
While I wasn't too impressed by the RULES of the diet, I was impressed by the idea that once per week you get a cheat day. Cheat days are all throughout popular diets, so it's nothing new, but what makes it interesting is WHY you NEED the cheat day. The author explains that it keeps your body from adapting to the calorie restriction and keeps your body in an intense fat-burning mode. Not only does he say to cheat, but he recommends "going nuts." His cheat-day example breakfast was 2 bear claws and 2 cinnamon rolls (or something, I can't quite recall). Dinner was a whole pizza. To eat that and maintain 12% bodyfat (as he claims) is pretty damned impressive.
Just throwing it out there, that the effect on BMR is not going to change the world. I am sorry but it is an overhyped effect. Also "intense fat burning mode" is, I apologize, hyperbolic bullshit. You have a BMR based on the amount of energy your body needs to maintain all the chemical reactions that goes on in there. That BMR can be tweaked, not radically altered. Then you add all the movement of the day to that BMR, or multiply it in. Now the multiplier can be radically changed, but the BMR can't. It is simply false to think that you can "keep your body in INTENSE FAT BURNING MODE" or "DESTROY your ability to BURN fat" because none of those things will happen. You can burn tons of calories through activity but other than that there is no wonder treatment. Amphetamine, adrenalin and ephedra, and to an extent caffeine can tweak your BMR too, but again besides combining ephedra and caffeine which have a tendency to kill people, you can't change it in any meaningful way.
Also, to think that all dieting can be summed up in calories in vs. calories out is just not right. It's definitely more complicated than that, else we'd all be fit from counting calories. For instance, why don't I subtract the calories that I poop out everyday? And if I work out intensely for an hour, how do I calculate the afterburn effect, and for how long?
I never claimed that you can count precisely, I simply explained that in the end, that equation is true and you cannot change that fact. You don't substract poop calories because the calories written in databases over calories from food is a number that includes the energy required to digest the food, and your poop. The afterburn effect is also over rated, but it is there, how does it change the equation. Does it say "also don't include afterburn in calories expended" somewhere in there? no.
And no, you don't get the book for free. I'm not any sort of spokesman for the book, but if you're interested in it, pick it up. I for one am always interested to hear about different ways to approach weight loss or muscle gain - I think it's the collaboration of all of that knowledge that helps me develop my own approach.
All the knowledge needed is available freely. Now for some people reading that what they are doing is REALLY GOOD is a good motivator, for some people a book is something to hold on to and some arbitrary rules might help them. Thats fine, it doesn't change my opinion about false claims, or the fact that they are false. It also doesn't make hyperbole true.
Finally, a note: I'm pretty skeptical about dieting. I've been eating healthy and working out for a while now (years). In that time I haven't weighed less than 166, and I've tried a few different methods (I'm not about to say, "I've tried EVERYTHING!"). I went on the diet last week and weighed myself yesterday... 164. Just sayin'.
Obviously those other methods resulted in your caloric intake being too high compared to your usage, and this approach resulted in you not eating more calories that needed for loosing weight, and I applaud you. Using that as an anecdotal piece of non-evidence and qualifying it with "just sayin'" just seems smug and doesn't really prove anything.
ffs, if it works for you, more power to you. Noone will argue that point. It is the hyperbole and woo woo that people object too.
