times a week (as some people will have you believe).
however, even though what i do today by way of exercise is less than i felt i had to do when i was overweight, and had bad blood pressure and cholesterol readings, even back then i never did more than 30 minutes of exercise in the gym, and never more than three times a week.
without going into too much additional detail it’s fairly safe to say that i have been able to maintain what i consider to be a great state of health primarily through the food i eat.
