@denny2019 Hi Denny, and welcome to Connect.
You have some great ideas here from @retiredteacher, @dorisena and @rosemarya — thanks for that link, Rosemary.
I have nothing to add in the diet area but I think you might want to increase your exercise. I generally exercise three times a week in the water — a 45 minute water aerobics class followed by another 45 minutes of water jogging. On three other days, I go to the gym at my health club and start with either the treadmill or elliptical and then do some of the weight equipment. I spend at least an hour in the gym. Recently I have been out of commission due to a femur fracture but I am now getting back to it. When I don't get to my health club I ride my recumbent bike at home for somewhere between 30 and 45 minutes. I try to go at least 7 miles.
The recumbent bike is a very good exercise if you have some resistance and spend enough time on it, plus you can watch TV while doing it to distract yourself from the exercise. Sometimes I end up going longer than intended because I want to see the end of a TV show!
I do not follow any specific diet but if I did I think I would check out the Mediterranean diet because it's supposed to be heart friendly too.
