I eat oatmeal and take protein shakes (post wrokout) too. It's good you eat potatoes because they are complex carbohydrates (slow burning carbs) and a good source of vitamin C. About the eggs... i'd only eat the egg whites (high protein, low calorie) but i dont eat the yolk (look up the nutritional value of the egg yolk on the internet and it will shock you). The Department of Nutrition says
"Eggs : An average egg contains about 5-6g of fat. The way eggs are cooked considerably affects the energy and fat content, therefore choose boiled, poached or scrambled (with skimmed or semi-skimmed milk) rather than fried eggs to keep the fat and energy content down. Also aim to keep egg consumption to approx. 3-4 per week."
If I'm not in the mood for oatmeal, I get wheat bread (also a complex carbohydrate) and get fish or chicken breast or any low fat, high protein substitute. I really avoid white rice.
I don't add butter or margarine (even if margarine is vegetable based) or sugar to any of what I eat too (i get my sugar from fruits). Where are your fruits anyway? Not even an apple? Oh and one last thing, I usualy start my breakfast with jasmine tea (it's a green tea with a blend) because it's gives me a more satiated feeling.
