NutriFuel

THE PROBLEM WE'RE SOLVING

Health-conscious travelers with professional nutrition support face a critical gap between their meal plans and real-world execution while traveling internationally. Frequent business travel, with timezone shifts and unfamiliar local food, consistently derails dietary efforts. Tracking tools become impractical, leading to frustration and cycles of feeling defeated. Progress is undermined by circumstances, not lack of willpower.

1) Key Pain Points

• 🌏 Language Barriers: Menus in foreign languages make it impossible to understand dish contents
• ⏰ Timezone Confusion: Time differences disrupt meal timing and hunger cues
• 📱 Manual Tracking Failure: Traditional apps require extensive time per meal searching databases
• 😔 Loss of Adherence: Travelers return home having abandoned their nutrition plans
• 💔 Disconnected Care: Nutritionist plans lack real-world execution support during travel

2) The Core Issue

Professional nutrition plans are optimized for home environments but become useless abroad. Language barriers, timezone confusion, and manual tracking tools designed for static locations — not international travel — set people up to fail.

3) Market Reality

Massive wellness tourism market with billions of annual international trips, yet no solution bridges professional nutrition care with travel execution.
