I am no longer an athlete or lifter, just trying my best to eat good and stay as healthy as possible. This is coming from an "average guy" perspective. I follow the below about 85% of the time.
Stay away from sugar, msg (excito-toxins), gmos, and processed things as much as possible. It's unrealistic to completely eliminate these items, and in small doses they are not harmful. But most people's intake of these items are multiples of 100% more than it should be every day and over time it's killing us and modifying our dna.
Breakfast: homemade bars with lots of goodies, nuts, seeds, etc.
Lunch: sandwich or leftovers from previous dinner, lots of fruit, trailmix, greek yogurt with frozen berries, raw veggies
Dinner: fresh protein, a starch, and a cooked veggie. Protein is usually chicken, turkey, or fish but occasionally pork or beef
The thing is, if you have a lot of spices you can make a simple chicken breast taste like a different restaurant quality meal every night. Just play with different combos. I used to spice while cooking but have turned to spicing while it rests except for spices that need some cook time. Meals take 30 minutes or less to make which is actually quicker than getting in a car, driving to fast food, driving home, and then eating.
I am not a total nut about it, still eat bread, cheese, and an occasional meal out. Also eat full fat everything, bought into the "low fat / no fat" scam for years until I started reading ingredients and wondering what exactly they put in its place. Turns out it was msg, lots of chemicals, and boatloads of sugar.
