Hi SquareOne,
Thanks for the kind words. I'm by no means an expert but I'm happy to share some of my habits. From what I've read, oldsters like us should aim for about 2 grams of protein per kilogram of bodyweight. I weigh about 192 pounds right now--87 kilos. So I try to get at least 175 grams of protein every day. Since you weigh 223 pounds, or 101 kilos, your target would be around 200 grams of protein as you said. I think whey protein isolate has really helped me. I typically have two protein shakes every day, with 2 scoops of whey in each shake. So counting the milk those two shakes give me about 120 grams of protein. I get the remaining 55 grams or so from my regular meals--oatmeal in the morning, chicken or fish for lunch, more of the same for dinner, along with lots of fruits, vegetables, and whole grains. I also supplement with 5 grams of creatine every day.
