Nothing wrong with egg yokes. Its total fat content over the day you have to worry about and the saturated fat it contains. When I make eggs, its usually 4-5 whites and a whole egg thrown in.
even though you want most of your protein coming from whole foods get a scoop of protein in that smoothie if you have to have it. Aim for 30g of protein in each meal. Unless your drinking 3 cups of milk, that won't cut it.
