Autophagy is a WIN WIN for everyone including strength athletes... whether in their mid 20s or mid 60s or anything in between.
This is a great article from Dr. Mercola who underscores a high fat diet, intermittent fasting, muscle building and high intensity training, 3 things that many of us participate in always. Dr. Mercola also understands as did Mike Mentzer that taking in more protein than what we require is not only a waste but can be damaging and negative. Enjoy the article! PS... I personally us a 3 to 6 hour window when I intermittent fast and train in a fasted state.
