Well... this is month three with my new Powerline P2X gym, and although I feel a stronger than I did before, and there is some visible physical improvement, progress is pretty slow even though I hit it just about every day. I guess a 63 year old guy just better temper his expectations and take better health as the benefit of working out. We're just not going to look like the ROCK...

... a little late for that. I told my VA doc that I had bought a gym and his reaction was an immediate... "GOOD." He said it helps oldsters later on in life with their balance and joint health. He also added that resistance/weight training can have profound benefits over just cardio exercise like walking and such.
Trying to overhaul the diet also, that's a slow process when your house if full of the things you're planning to swear off.
I agree with the resistance weight training so long as we know what we are doing and don't expect miracles after a certain age. And since 60 became the new 40, nothing much is ever too late to start something that makes us healthier and improves our lives. I have learned and accepted that shedding unwanted pounds after a certain age is no easy feat but can be accomplished if we understand that the trend is more important that what the scales show. As I recall, you don't have a problem with excess poundage though.
My counsel re diet is not to eliminate foods we love and would seriously miss unless we have an allergy or other intolerance to those foods and they are making us sick. Giving up everything we really enjoy eating just makes us feel deprived. What I do and try to do for Hombre--he's a bit more stubborn about that than I am

--is change the proportions. I try to enjoy smaller portions of the less-than-stellar stuff I love, like fried chicken, and fill up on the lower cal veggies. I still enjoy dessert but a smaller portion than I used to take and satisfy my sweet tooth with fresh fruit or such.
We do avoid most processed foods these days and prepare meals with fresh or frozen ingredients. Using frozen fruit and veggies are sometimes healthier than fresh because they are harvested and flash frozen at peak quality and have all their vitamins and minerals intact. But I still like to use fresh fruit and produce especially locally grown and recently harvested when I can get it. Nothing you buy at the super market can compare to a vine ripened tomato out of your own garden.
