Since the thread started with a troll-ish title ("the sky isn't blue" is incorrect, "the sky isn't my preferred shade of blue" may be correct), I'll entirely ignore the original intent and instead weigh in with my general eating perspective here... I've read the China study, lots of articles on various ways of eating, you name it... Trying to find the truth, but all I found were contradictions and confusion. In the end, I settled on something that sort of resembles Paleo. Not because of the hand-wavy, foaming at the mouth anti-grainism, but simply because my personal weight problem was caused by eating too much grain-based stuff. Body gets low on energy, body freaks out, tells your mind to make you eat something super carb-rich to replenish (We're not starving, we have a pantry full of white bread! Go eat some!). Inevitably you overeat by a bit, and that extra gets stored as fat. If I don't grab some toast or cereal as a snack and instead grab an apple, I get full enough but still don't have enough carbs to fuel myself, so my body is forced to burn fat for energy. Plus, the apple sneaks in tons more other types of nutrition my cereal or muffin snack would not have. Or so my potentially flawed understanding goes. Found the info in this great article:

So I don't eat ANY bread, pasta, etc. at home. When I'm out with friends - whatever, who cares, what I do today isn't the problem, what I do *every* day is the problem. At home, I eat mostly fruit, nuts, vegetables (not many) and meat. I eat eggs, coconut water, and maybe a banana or two for breakfast. I have one major meal a day, usually in the afternoon (soy steak and brocolli stir fry, etc), and graze the rest of the day - some nuts and raisins here, a raw bell pepper there, an apple and some almond butter over there.
Net result, lost 7 pounds in the first 2 weeks, felt much better. It works, and I'm not hungry by any means. When I stopped freaking out and trying to find the exact right thing, and instead started doing *something*, it worked. "The perfect is the enemy of the good."
May work for you, may not. Take it as you will.
