why fueling isn’t one-size-fits-all

You train smart. You train hard. But if you’re still struggling with bonking, GI distress, sluggish recovery, or just not feeling your best—you’re not alone. A lot of athletes think they’re fueling correctly, but don’t fully understand one simple truth: fueling is a sport in itself.

One common mistake? Not knowing when (and how) to mix liquid and solid fuels during training or racing.

At Skratch Labs, we make it easy to figure out what works for you with real food, functional sports nutrition, and zero BS. Unlike brands that either oversimplify (“one product fits all!”) or overwhelm you with jargon, we believe in keeping it real, flexible, and athlete-first.

liquid vs. solid fuel: what’s the difference?

Liquid Fuels

Think: easy-to-digest, easy-to-use, and critical when chewing isn’t practical.

• Perfect for high-intensity efforts, sensitive stomachs, or when you’re breathing like a freight train.
• Helps you maintain hydration while delivering quick, steady carbs.
• Example: Skratch Labs Super High-Carb Drink Mix — 100g of carbs per full serving without needing solid food.

🔬 Science Says:

Studies show that carbohydrate solutions can enhance endurance performance by maintaining blood glucose levels and delaying fatigue, especially during continuous, high-intensity exercise (Jeukendrup, 2004).

Solid Fuels

Think: satisfying, flavorful, and great for variety.

• Ideal for longer, lower-intensity efforts or when you’re actually hungry.
• Gives your brain and gut a sensory break (and keeps morale high).
• Example: Skratch Labs Energy Chews and Energy Bars — soft, real-food based, and built for endurance.

🔬 Science Says:

Chewing and digesting real food can stimulate different gut hormones and support better gastrointestinal tolerance on longer efforts (Costa et al., 2017).
