I will vote for variety being good - for body and mind health. I like to carb cycle sometimes, on a whim, if I feel like I'm dragging after VLC'ing for a few weeks. Not only do I feel fine or better when I do that, but each time my abs get a little more defined.
Is variety good as a chip in this game of life and keepng the mind and body fit? Yes. But it's also irritating and I want change about as much as a clown fish wants a bicycle. Mostly, I want life to leave me alone; to stop offering me challenges and silly opportunities to grow and change. You know that point in your school quiz when you realize you know all the principles, even if you can't answer every question, and you're ready for the test to be over so you can put the pencil down? Yeah. That's where I'm at. I'm 30. I've survived bullying, poisoning, malnutrition, an enabling and co-dependent lifestyle in three dfferent flavors, come back from the blurred edge of genuine insanity, neglect, my own attempts to self-destruct and the humility of buckling down and being a good house husband. Let me rest now. Waiter? Yes, three heaping scoops of boring please, wth a side of peace and quiet and a silent mind.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
