Bob, your name defiantly seems familiar. Likewise I'll be 58 this year and I was 235 pounds, now I am down to 163. My recommendation to you is to change your diet and lifestyle, I know its hard but its well worth the health benefits. The first thing I changed (or was rather forced to change) was my diet, the doctors put me on the Mediterranean diet (you can look it up online but basically fruit and veggies, chicken and turkey with no skin or fat, red meat only twice a month (we only do bison or venison) and as much fish as you want), they also restricted my sodium, sugar and fat intake (no cheese, gravies or creams), Once you get used to eating like this and knowing its for your health, your taste buds will eventually get used to it. We now spend considerably more time shopping for food and we educated ourselves about nutritute (I got some help here from the VA and from my Cardio Therapy training), there are several apps you can download on your phone (Yuka) that you can use to scan barcode labels at the grocery store, you'll be surprised what is and what is not healthy. But to loose weight besides the diet and kicking sugars (pop, donuts, cookies, cake, candy bars, ice cream, etc) you need to exercise. After the heart attack I started to slowly walk around the block with my wife, then overtime I got upt 2k steps a day, then 3k, about six weeks after the event I was offered to got to Cardio Therapy for six weeks, I took it and they not only trained me in nutrition but also trained me in how to exercise properly (the VA has some programs I think and there should be some free resources here), you'll need to start off slowly, I started off with 5 minutes on the bike, 6 minutes on the treadmill, 3 minutes on the elliptical, 5 minutes back on the bike and 5 minutes on the treadmill and topped it off with 3 minutes on the rowing machine. I am now up to 15 minutes on the bike, 15 on the treadmill, 15 on the elliptical, 15 minutes back on the bike, 6 minutes on the rowing machine and 20 minutes lifting weights (I am only doing 8-10 pounds for strength maintenance and also am still on a lifting restriction of 50 pounds).
Most of all give yourself grace in both diet and exercise.
The last part (but most import to me at least) is my faith in God and how he saved my wife from becoming an early widow at 50.
Balance and love.
Take care of yourself Bob (and the rest of you fine gentlemen as well).
