My breakfast goal is always high protein, high fat, low carb. It helps keep me sated early in the days and lets me eat more carbs later before/during/after workouts. Thus:
Weekdays (before w*rk):
~2/3 cup (4%fat) cottage cheese
~1/3 cup 2% Kefir
scoop of vanilla whey protein isolate powder
1/4 - 1/3 cup of blue/rasp/blackberries
Mix really well
If I'm training a lot (triathons), I'll add some granola to this. Also take my fish oil in the morning, and drink a tall glass of water with my coffee/heavy whipping cream.
Weekends:
3 eggs scrambled w/ salsa
1/2 avocado
bacon
fruit (berries or tangelo...)
Water/coffee/fish oil.
I've found the morning kefir, as well as unrefined potato starch with water before bed, have really helped my digestion.
