Dr. Spencer Nadolsky on Losing Weight, When to Diet, and Weightlifting for Weight Loss

How much attention do you need to give to your weight as a runner?

Dr. Spencer Nadolsky is an obesity and lipid specialist physician who’s helped thousands of patients across the US.

After competing on a college track team in the horrible early 2000’s culture of “lighter is better,” I wanted to bring a medical expert onto the podcast to discuss weight loss in a responsible way.

We talk about:

• The balance between fueling for performance and the potential need for weight loss
• Assessing whether weight loss is clinically indicated or potentially harmful
• Focusing on nutrition rather than just running more to lose weight
• Body composition and maintaining muscle and bone mass
• The risks of RED-S and what both men and women should look out for
• Nutrition recommendations for runners
• Thoughts on weight loss medications like Ozempic for runners

Thanks to MOBO Board!

Invented by renowned physical therapist Jay Dicharry, MOBO helps you stabilize your stance with an innovative rocker board that’s set up on two fins. The design effectively forces you to drive your big toe into the board to improve your stability. I was pretty arrogant going into my first session on the MOBO Board. How hard can it be to balance, right? Well, I was humbled pretty quickly!

Even if you’re a good runner, better balance, stability, and proprioception is going to help you have a more powerful stride and prevent more running injuries. You’ll learn how to improve the efficiency of the kinetic chain from your hip to your big toe. Because as Jay likes to say, it’s not just how strong you are, but how well you use that strength.

I was recently at a weekend physical therapy workshop (lol I was the only running coach) and learned how
