as someone who's lost a lot of bodyfat, kept if off, and is in the process of getting rid of the last of it, I would re-arrange the numbers and consider dropping a few. I believe that #5 is absolutely critical (though I disagree with the distribution of macronutrients), and #1 may be irrelevant. I disagree with #6 also -- anything that smacks of boring or deprivation is a recipe for failure.
#2-4 are in the proper order as far as I'm concerned.
I also believe it's natural to get about 40% of your calories from fat. There's too many carbs in the formula you've given. for me the key in #5 is to adopt principles of eating, not trying to count calories or macronutrient proportions. Eat real foods (in the US, that means shopping the perimeter of a supermarket and avoiding most of the interior), lose your fear of dietary fat, and avoid added sugars, esp. HFCS. Those three steps alone I think would do enough for most people to put them at a weight they can reasonably expect. With no added exercise (I know, that's heretical too).
Right now I'm in the midst of a self-debate over artificial sweeteners. I literally grew up with aspartame (Diet Coke is the family drink, as ridiculous as it sounds), and rely on it and sucralose more than I'd like. I'm not convinced of the scare-stuff (eg. aspartame causes everything), but I'm coming to conclude that anything that throws off your body's ability to judge calories by taste is bad for you. That said, I really like ON whey, low-sugar yogurt, and i'm still mildly addicted to diet sodas.
Oh -- and the photo attached to your article is hot
though perhaps unrealistic esp. for most gals.
