M2M great post of balancing life. Congrats on making a commitment to your health. This is one you'll never regret indeed. I wish I would have done so at your age instead of your grandfathers!
I've made some big diet changes very similar to your's but I have eliminated grains pretty much completely from my diet. I eat a shit ton of veggies and meet. gyms is spot on with the magnesium and zinc as well.
Keep rocking life sir!
