And carbohydrates-drive-insulin-drive-excess-fat-accumulation, where fat tissue is regulated by insulin, and insulin is disrupted/stimulated by dietary carbohydrates. All others are just variations of these two. Try to categorize your list like that, you'll see what I mean.

Also, check my blog (link in my signature) and the post titled "Paradigm - Progress". It could be considered a hypothesis on its own, though I prefer to think of it as a paradigm, a collection of hypotheses. This paradigm fits in the carbs-insulin-fat-tissue category. Just ignore the part about my personal health.
