#90: Peter Defty Talks Optimized Fat Metabolism
Host Brad Kearns connects with Peter Defty, promoter of Optimized Fat Metabolism and Vespa energy food: Vespapower.com. Peter is a very early promoter of fat adapted training, and is a successful ultra distance athlete, with many marathons and a Western States 100-mile Endurance Run finish. Since the early 2000s, Peter has coached other athletes to optimize their fat metabolism, including some world-class performers like Zach Bitter, Nell Stephenson, and many others.
This is a lively show with an analysis of some contentious issues in the current fat adapted training scene. Defty is promoting a “MMAF” – Modified Maximum Aerobic Function. Basically, the idea is that fat adapted athletes can increase their aerobic training heart rate by some 20 beats, because of their optimized fat metabolism and improved cardiovascular system function. This is a pretty big deal because MAF is being promoted as the end-all for aerobic conditioning.
Defty suggests that fat-adapted training improves cardiovascular function to the extent that athletes might even see an increase in maximum heart rate. This is some provocative stuff that will be interesting food for thought for endurance athletes out there who are dedicated to aerobic training and fat-adapted eating.
