This bonus episode of Your Diet Sucks is brought to you in collaboration with Skratch Labs, creators of science-backed hydration and fueling products made for athletes and anyone who sweats on purpose.

Whether you're training for an ultramarathon, recovering from a high-intensity workout, or just trying to feel more human after hot yoga, this episode is packed with insights for you.

Zoë sits down with Dr. Allen Lim, exercise physiologist and founder of Skratch Labs, for a deep and honest conversation about performance nutrition, hydration science, and the emotional side of fueling.

• Why GI distress happens during training and racing—and how to avoid it

• How to personalize your sports fueling strategy, even if you’re not an “elite athlete”

• The science of salt, sweat, and hydration (and why it’s more complex than you think)

• Allen’s “me-search” approach to product development at Skratch Labs

• The truth about power-to-weight ratios, diet culture in endurance sports, and how fueling supports identity, community, and joy

• Why progress matters more than perfection—in training, nutrition, and life

💥 Whether you're an ultrarunner, cyclist, triathlete, or sweaty human in search of smarter fueling—this episode is your go-to guide.

We promise: this is not just a long-form ad. It's a real conversation about how to take care of yourself when you’re asking your body to do hard things.
