People should forget most of the study results on diet and exercise and do what works for them. It doesn’t take a genius to figure that out, but looking at every new opinion can be problematic. Lots of unfit people who have or have had pet experts. In fact, more times or not ,when someone is busy taking sides with the latest opinion , I find that their actual program isn’t all that or won’t be soon. They become members of the unhealthy “I tried that for a while” club.
