About our guests:

Screen Shot 2015-05-07 at 7.00.04 AMBob Seebohar, MS, RD, CSSD, CSCS, created the concepts of nutrition periodization and metabolic efficiency training. He specializes in enhancing health and improving performance by improving metabolic efficiency and using nutrition periodization. He’s served as a sport dietitian for the US Olympic Committee and the personal sport dietitian for the Olympic Triathlon Team, and much more. Read Bob’s blog.

Dina Griffin is female endurance athlete who gets it. She earned her master’s degree in Food Science and Human Nutrition and is a Board Certified Specialist in Sport Dietetics, and is a wealth of knowledge on metabolic efficiency, fat adaptation, and achieving health and performance. You may remember her from our metabolic efficiency test last year when Tawnee was tested in colorado and the two analyzed the results. Dina practices what she preaches as a triathlete and ultrarunner who completed Leadville 100 last year.

Covered in this show:

  • Metabolic efficiency (ME) and fat adaptation through sensible nutrition, and why ME is not equal to low-carb
  • Carbs! Tackle high fat vs high carb (or traditional carb fueling) for endurance athletes
  • How did Dina and Bob’s philosophy on sports nutrition evolve into what you believe in and recommend today?
  • Why you want ME and how carbs fit into the picture including traditional high carb vs low carb, timing of carbs, etc.
  • What the research really says about low-carb and ME for athletes (and this may surprise some of you!)
  • Describe a typical metabolic test and how you then make recommendations for that athletes?
  • If someone is a sugar burner how do you lay out a plan to shift that to more fat burning?
  • How long till you get results?
  • What do they typically see in lab tests on athletes?
  • Is testing necessary or can we guesstimate?
  • Should nutrition be periodized for training and the race season? i.e. High fat with base phase/lower intensity, then high carb with build/race phase, or is that outdated and we can remain lower carb in periods of more intensity?
  • Thoughts on timing of macronutrients and carb refueling; when to eat your carbs (AM, PM, during training, etc)?
  • Real-life recommendations for athletes and types of foods you should be eating and should be avoiding
