126 – Dina Griffin – Fuel is Not One Size Fits All

Dina Griffin, also known as “The Nutrition Mechanic,” is a Board Certified Sports Dietitian and Registered Dietitian Nutritionist based out of Boulder, Colorado. She consults with all levels and abilities of endurance athletes nationwide by fine-tuning daily nutrition strategies to optimize health & healthspan, and training and competition strategies for maximum athletic performance. Some of her specialty areas include female athlete health, type 2 diabetes, weight management, and metabolic efficiency training™.  She takes pride in treating each athlete with a personalized approach while aiming for a sustainable “food approach” that works within each person’s lifestyle.

Here’s the cool thing about Dina. She’s not a student or lab rat who doesn’t really understand what it’s like to be an athlete. Dina is a competitive endurance athlete. She has completed over 10 marathons (including Boston), the Leadville 100 trail run, the Comrades ultra marathon in South Africa, Ironman, and several other triathlon, ultra running and cycling events.

Dina is chock full of knowledge on all sides of the spectrum. What you may find frustrating is that her belief is that there is no formula that works for all, that people have a huge array of different needs based on so many personal factors. What you may find exciting is that you can tap into your personal unique formula through testing and other methods so that you can create your own recipe for success.

Today we cover:

  • Poop: yep poop. Check out the Bristol stool chart to analyze yours. Regularity is also part of the discussion
  • Sugar: Different types of sugar used (or abused) as fuel
  • How to find your optimal formula: blood testing is key
