1) no breakfast magic. It's daffy to eat without an appetite.
2) macrats usually aren't worth the stress IMO--far better to make the best choices within each category (the hazards of excess protein/carb/whatever are hard to encounter unless you dip into refined foods). Keep in mind that part of your "diet" will be stored fat so no need for precise reckoning. My arbitrary starting point might be 20%BMR protein, 20%BMR carb, and as much fat as you need to make food edible (plus some eggs/coconut/seafood for their unique nutrients).
