Zach: Saying that I'm genetically pre-disposed to metabolic syndrome is stating a fact, it isn't a cop out. Of course, it was my choices that untimately made me gain weight. You can have every genetic risk factor for weight gain that we know of and not be overweight.
If I go out to lunch and eat mac&cheese and leftover Valentine's Day cupcakes, it'll be my choice...and it'll be a bad one! It's not avoiding responsibility to eat a diet your body can best work with and what your body can best work with IS determined by your genetic makeup.
As for restricting micronutrients....what do you call what low-fat diets do?
