The Fuel Check
Most tools judge one food at a time on calories. This one scores your whole snack stack on carb quality — glycemic load, fiber, protein — against your goal. Build a stack and see.
1 · Your goal
Accessible carbs to power a run or ride.
2 · Build your stack

How the Fuel Check thinks
Carbs aren't good or bad in a vacuum — it depends on what you're fueling. We weight five signals differently per goal: carb energy, glycemic profile (GI & glycemic load), fiber, protein and added sugar. An endurance goal rewards fast, accessible carbs; a steady-energy goal rewards a low glycemic load and fiber. The score reflects fit, not calories — because a banana before a long run and a banana at your desk are two different decisions.
Frequently asked
How is the Fuel Score calculated?+
We total your stack's carbs, fiber, sugar, protein and fat, weight its glycemic index by carb content, and score the combination against goal-tuned targets — so the same snacks score differently for endurance vs steady-energy goals.
Why score the whole stack instead of one food?+
Because you snack in combinations. A high-GI food paired with protein and fat behaves very differently than on its own. The Fuel Check judges the real-world combination.
What makes a good endurance snack vs a steady-energy snack?+
Endurance fueling rewards accessible carbs and lower fat for fast energy. Steady energy rewards a low glycemic load and high fiber to avoid spikes and crashes. Same database, different targets.
Is this medical or dietary advice?+
No — it's an educational tool using reference nutrition data. For medical nutrition therapy, consult a registered dietitian or doctor.
