I eat the same 5 meals every day, over and over, and have for quite a few years. Then on my "cheat days" where I carb load, I use the same "safe starches" over and over.
According to my lab work, I'm perfectly healthy and have no deficiencies in my nutritional status due to my diet.
I do however, supplement with fish oil, vitamin D, and a daily multiple vitamin.
My meals are:
Meal 1: 2 whole eggs with 1 ounce sausage, 1 ounce ham, 2 strips bacon, 1 slice cheese, diced tomatoes and peppers.
Meal 2: 5 ounces tuna with mayo and a cup of lettuce (I usually use olive oil mayo made at home with olive oil, eggs, and seasonings - recipe is free on my web site if you want it.)
Meal 3: 1 whole chicken leg quarter, green vegetable of choice (most often turnip greens or broccoli)
Meal 4: 5 ounces tuna (see meal 2).
Meal 5: 8 ounces beef (steak, ground chuck, etc...), green veggie of choice (often greens, a big salad, or green beans).
My carb loading days usually consist of basically the same but I add potatoes to each meal that doesn't include tuna and lettuce and eat 4 or 5 pieces of fruit. I extend carb loading to breakfast the next morning.
Repetitive eating may not be optimal but for those of us on a tight budget (I've just opened a gym and it took all my money to do so...and am supporting it on a paramedic's salary)... it works. if you aren't having any problems from it, then keep doing what you have to do... even if your diet isn't optimal, it's far, far better than S.A.D. And you are still better off than the pizza eaters out there.
