Been training (weights mainly) for a while now but need to focus more on diet to see best results. Gonna follow some examples to start with (Mens Fitness etc) but they all have fish on some days. I can understand this due to its good source of protein, omega 3 etc. Basically, i can't stand fish, none of it, so what's the best thing to substitute it with on those days? Can you have too much chicken??

Cheers, Chris
