I've been doing an egg white fried in coconut oil and a teaspoon of almond butter with a black coffee for pre workout (it's just a little snack but I feel like it helps before a 6am gym sesh, cos I train quite early I only have half an hour to digest so don't want to eat too much.
Then I've been having my post workout + breakfast combined cos I'm quite short on time and need to have something portable I can eat at work. That meal usually consists of some pre-made egg fritatas (2 - 3 eggs with asparagus, tomato, baby spinach) and a piece of fruit like an apple or mandarin.
Does that work?
Nuts are generally harder on your stomach than egg yolks. The majority of the great stuff in an egg is in the yolk, so you'll get more of a nutritional bang for your buck if you just eat the whole egg. Plus you won't be wasting the yolk.
