I am in my 70’s and my lifetime experience says exercise 4 times a week for 30 minutes is superior to any diet or meds. It will keep your blood sugar levels, avoid joint pains in knees and hips, help a great deal with blood pressure levels, and greatly improve energy level.
That reminds me, I have to go do my treadmill now!!!
