## What is Sustain?

Sustain is the nutrition companion built for people on GLP-1 medications — Ozempic, Wegovy, Mounjaro, and Zepbound.

The medication handles the weight loss. Sustain handles what it can't: protecting your muscle, managing the day to day, and keeping your results once you get there.

PROTEIN-FIRST TRACKING
Log food by search, barcode, photo, voice, or one-tap staples. Half-portion logging built for smaller GLP-1 appetites — no more editing serving sizes down. Protein is the hero number, because muscle is what's at risk.

KEEP IT OFF
A Retention Score tracks how well you're protecting your results, with a maintenance and off-ramp mode for life after the drug — the phase most apps ignore.

AI COACH
Ask about protein, energy, side effects, or muscle. Answers are grounded in your own logged data.

BODY COMPOSITION
Track lean mass vs. fat, not just the scale. Watch fat leave while muscle stays.

FOOD NOISE, MEASURED
Log the mental food chatter and watch it quiet over your dose cycle.

SMART REMINDERS
Dose-cycle, protein, hydration, and meal-variety nudges — tuned to a GLP-1 routine.

DOCTOR-READY
Export a clean PDF summary for your appointments.

Sustain provides general wellness and nutrition guidance, not medical advice. Always consult your healthcare provider about medication and dosing.
