Our diet and fueling habits are setting important examples for our kids. Are we doing it right?

Joining me is coach Michele Pettinger. She’s a Level 2 certified coach through the Road Runners’ Club of America, a certified specialist in fitness nutrition through the ISSA, and she’s the author of the new book The Young Runner’s Guide to Nutrition.

We discuss how young runners should be fueling and approaching nutrition (which during the teen years is a formative time period). It’s critical we get the basics of sound nutrition habits right early so that we can set kids up for success. We also chat about practical strategies for families and coaches, the impact of puberty on our nutritional needs, simple ways to make optimal fueling easy, and why Michele thinks my tradition of bringing my kids to McDonald’s after a hike in the mountains is just fine.

As a dad, this topic is really important to me. I’ve been around young runners and unfortunately, disordered eating is not rare. Hopefully this conversation will help you navigate food, nutrition, and fueling in a more thoughtful way with the young people in your life.

Thank you Previnex!

After resisting most supplements for the better part of my life, I’m cautiously changing my tune. I’m now a Masters runner and in my personal life, I’m optimizing for longevity. I want to be my healthiest self for as long as possible and I’m excited to partner with Previnex to make that happen.

Previnex uses the most bioavailable, clinically tested ingredients, the optimal form and dose of each ingredient, pharmaceutical grade manufacturing, testing of raw ingredients and finished products. For every purchase you make, they also donate vitamins to kids in need.

Their new Muscle Health Plus is something I’m now taking. Turning 40 – and having a thin frame – has made me realize that I need to prioritize lean muscle mass to stay healthy and age well. Muscle Health Plus has creatine, essential and branched chain amino acids, and it’s designed in a way to maximize protein synthesis and the absorption of amino acids.

Muscle Health Plus will help you prevent muscle damage, which is particularly important for aging runners who want to protect themselves from muscle loss and recover faster after hard workouts.

Thanks to Ketone-IQ!

Ketone-IQ increases the levels of ketones in your blood – and raised blood ketone levels do increase focus and alertness, which is why I take a shot before every podcast recording and have for almost two years even before their sponsorship. I feel dialed in and quick for these high-stakes conversations.

There’s also promising research – and loads of anecdotal evidence – that ketone supplementation can help with recovery if taken post-exercise. I know some of the best ultra runners in the world, Boston Marathon champ Des Linden, and the pro cycling team that won the TdF in 2022 and 2023 all take ketones post-race to aid recovery.
