Pro tip: Researching Roman soldier diets clarified my protein confusion.
Reading about how legionaries subsisted on wheat porridge, bacon, and sour wine made me realize how much modern fitness nutrition overcomplicates things. I started incorporating more whole grains and preserved meats into my meals, and the simplicity is refreshing. It's funny to think that a two-thousand-year-old mess kit might hold more wisdom than today's supplement aisle. My gains haven't suffered, though I do skip the vinegar wine.
