I'm pretty sure that your body goes catabolic only after a high-carb meal. Carbs are absorbed relatively quickly, so you find yourself hungry only a few hours after, say, a cheese panini, versus a comparably sized bowl of hearty meat chili, which is slowed down in the GI by all the protein and fiber. I'd propose that the frequency of your eating is determined by what it is exactly that you're eating.
1) eat real food - more vegetables, moderate meat, moderate fruits, less grains, less sugar, less vegetable oils.
2) exercise - moderate intensity cardio, sprinting, heavy lifting, dedicated stretching and mobility.
3) live - relax, de-stress, meditate.
