Endurance athletes, call your mothers!

This week on Fuelin Sessions, Scott is joined by Dr. David Lipman to explore where nutrition, exercise, and longevity meet. They cover mitochondrial health (and this little-known mother factor!), the importance of exercise as we age, and what to make of things like infrared light therapy.

The takeaway? Consistency beats perfection every single time.

In disciplines like cross-country skiing, athletes don’t follow static meal plans. Nutrition changes with training load, intensity, and recovery demands.

Your training changes, too.

Fuelin adjusts your nutrition to match your workload—automatically.

If you’re ready to stop guessing and start fueling based on your data, it’s time to try Fuelin.

That’s why we fuel him differently. 🌯

Louis is a Fuelin user who is training for an Ironman. He spends all day on his feet as a building and grounds supervisor.

He brings a full-sized cooler to work every day so that he can follow his nutrition plan.

“I’m losing fat, gaining muscle, and have more energy to get my workouts done,” he says. 🤩

Sodium needs can’t be determined by sweat losses alone.

For endurance athletes, this reinforces an important principle: Hydration planning should consider both fluid replacement and sodium intake together, not in isolation.

In the latest Fuelin Sessions episode, Alan and Scott walk through how athletes can practically apply the evidence.

Research shows that blood sodium doesn’t drop just because you sweat a lot. It drops when athletes replace a high percentage of fluid losses without sodium.

For many people:

Replacing ~70% or less of sweat losses → blood sodium stays stable

Drinking more than that → sodium can help prevent dilution

So the question isn’t “How salty is your sweat?”
It’s “How much are you actually drinking?”
