Just to break it down:
6 egg whites: 99 cal, 0 fat, 2 carb, 21 prot
1/2 c oatmeal: 145 cal, 2 fat, 25 carb, 6 prot - Total: 244 cal, 2 fat, 27 carb, 27 prot
1 whole egg + 2 whites: 134 cal, 7 fat, 2 carb, 14 prot
1/2 c oatmeal: 145 cal, 2 fat, 25 carb, 6 prot - Total: 279 cal,10 fat, 27 carb, 20 prot
Doesn't look like that big a deal. Jeez if 7 g. of protein kills me cuz I'm female, I would've been dead in 2000. The fat in the whole egg would help slow digestion for your first meal of the day.
