Plus, I find that eating "clean" (nothing pre-made or heavily processed) not only keeps you healthy but makes it hard to get fat in the sense that: the lack of calorie density, vast amounts of fibre and nutrients alone will keep you satiated for longer periods of time. Nuts are crazy, though. I love them, but they're some of the most calorie dense things I've ever seen. Almost up-there with eating raw sticks of butter. Almost.
