Your War and Peace reference regards a totally different era in which people were concerned with starvation and Arnold is referring to bodybuilding. You cannot build a massive body full of muscle if you don't eat a lot of protein so that's what Arnold is talking about. And you cannot have radiant health and beauty if you are starving.
I think you should just eat your eggs and yogurt and go from there. It's what you want to do anyway. At some point in your life maybe you will come to understand that a strong body with heavy bones and plenty of muscle will be an asset in your old age and maybe being strong will interest you then.
