System Architecture / The Concept
Your power meter logs every pedal stroke. Your heart rate monitor captures every beat. Yet the moment you unclip, most athletes revert to guesswork: estimating intake, hoping for recovery.
Avitu helps you get in control of your metabolic system. Built on proven physiological formulas, we help you determine nutrition targets based on a holistic view of your training and recovery. Track your nutrition with precision to optimize glycogen replenishment, protein synthesis, and gut health.
Calibrated
Glycogen targets derived from your actual training load, not generic charts.
Transparent Logic
Formula shown for every target calculated. Tap any number to see the science.
Deterministic
No AI estimates. Reproducible, verifiable output from established physiology.
Why Avitu Is Different
01 / Algorithm
Every target is calculated from proven scientific formulas. You can audit every number.
02 / Instrument
Avitu doesn't tell you what to eat. It shows what your body requires based on your training stress and daily structure.
03 / Performance
Context is everything. Avitu understands Zone 2 fueling, carb loading, and post-ride recovery windows.
Core Features
Precise nutritional needs based on your training. Know your protein, carbohydrate, fat and fiber targets to the gram.
Easily track your meals and snacks throughout the day. See how your intake aligns with your targets.
Carb-focused targets for in-activity fueling.
Platform Integrations
Connect your training platforms. Avitu ingests your activity data and biometrics, and converts them into precise fueling targets.

FAQ
Avitu uses established physiological formulas to derive your daily macro targets from your training plan, day structure, and athlete profile.
Avitu integrates with Intervals.icu (training plans, activities, biometrics), Strava (activities), and Wahoo (activities). Once connected, your training data is automatically synced to generate accurate daily fueling targets.
MyFitnessPal is a passive food diary with generic, static targets. Avitu is a performance fueling instrument: your nutrition targets change every day based on your training plan and context. A Zone 2 day has different targets than a threshold interval day. Avitu understands glycogen demands, recovery windows, and carb loading.
No. Avitu is deliberately algorithm-based, not AI-based. Every target is derived from proven scientific formulas. The output is deterministic and reproducible: the same inputs always produce the same targets.
TSS (Training Stress Score) is a standardised measure of training load derived from ride duration and intensity relative to your threshold power or heart rate. It directly correlates with glycogen depletion. Avitu ingests your TSS from connected platforms and uses it to calculate precise carbohydrate targets for recovery and next-day performance.
