Host Brad Kearns keeps the momentum going with another Maffetone show, this time getting personal with questions about Brad's training methods and competitive results. Phil details his proclamation that you need never exceed 90% of max heart rate, even on your high intensity sessions. He describes the concept of "positive overreaching;" you need to stress the body to improve, but not too much that you break down or get into an over-training state. It's not the stress of occasional hard workouts that's troublesome, but the accumulation of stress that will "bury you," says Phil - and reminding us that it's not just training stress in the equation but life stress too.    Brad bitches and moans to Phill about his "crash and burn" patterns, where he feels super and performs magnificent athletic feats one day, then heads into low periods where he drags in the am and needs a nap in the pm. Phil suggests that despite "normal, healthy" blood work and medical results, that something is indeed wrong, and that Brad (and other athletes) needs to do some detective work and n=1 experiments to look for solutions. Sometimes extreme experiments are warranted, such as a ketogenic eating period (recommended to Brad, who will try it again after a 3-week effort in April). Some more tidbits from Phil for athletes looking to maximize performance and health: ditch all refined carbs, of course, forever, no matter who you are! You become more insulin resistant with age, meaning you should eat fewer carbs; don't be afraid to use the "F" word - that is, eat plenty of fat so you don't backslide into carb cravings.   What is the difference between health and fitness? [00:00:52]

When an athlete performs well over the years, eats healthy, sleeps plenty and then has a crash and burn. What is wrong?  What can he do? [00:19:26] 

It is a good idea to do a personal experiment with diet for several weeks to analyze this fatigue problem. [00:27:39]
