Bodybuilders are morons for eating plain chicken and rice, you could get the same amount of calories and protein from eating something with actual flavour. Cooking is easy, there is no excuse to eat crap food in this day and age (and McDonalds is crap, you can make better yourself). I can't bake for toffee though...
I've just made a great fish pie, perhaps high in calories due to the butter in the sauce and mashed potato but worth it 
Pie crust is pretty easy. Use a ratio of 3:2:1 by weight for flour, butter, and water, and add a bit of salt. Put the cold butter, flour, and salt in a bowl and squish the butter (precut to manageable size chunks) between your fingers until you've got a bunch of pieces about the size of your fingernail around (but thicker is ok) in the flour. Add the water (ice cold) and mix with your fingers, but only until the dough comes together, adding just a touch more water if needed. It's supposed to look a bit lumpy and shitty, not like a smooth dough. Press it into a disc shape and fridge it (wrapped) for about an hour, then roll it out and line your pie tin. Put the lined tin back into the fridge for another hour before baking it so it doesn't shrink.
Overmixing/ overworking the dough will make it tough, fight you during rolling, and shrink in baking. Some people like cake/pastry flour to overcome this but all purpose is fine if you don't overwork it. Squishing the butter into very small bits will make the crust tender but without flaky layers (do this for pies with liquid fillings that get added after baking the crust separately). Throw in some sugar for sweet pies.
