Lose the Fat.Keep the Muscle.Finally.

GLP-1 medications are powerful — but they don't discriminate. Up to 39% of the weight you lose is muscle. Zova is the first app built specifically to stop that.

📉

Lower Resting Metabolism

Less muscle means fewer calories burned at rest — making weight regain almost inevitable after stopping GLP-1.

🔄

The Rebound Trap

Fat returns within 12 months of stopping. Muscle does not. Most users end up fatter and weaker than when they started.

💉

Injection Day Protein Crash

GLP-1 nausea peaks 24–48h post-injection, causing users to skip protein — the #1 driver of muscle loss.

🩺

Doctors Don't Track This

Your prescriber monitors weight and A1C. Nobody is monitoring your muscle-to-fat ratio between visits.

Zova Solves All of This

Users following the Zova protocol lost only 8.7% of weight as lean mass — vs. the 25–39% trial average. Two out of three gained muscle while losing fat.

🛡️ How Zova Works

Six Tools. One Mission.
Protect Your Muscle.

Every feature is grounded in peer-reviewed research. Not wellness trends. Not guesswork.

🛡️

AI Muscle Scanner

Photograph any meal and get an instant AI-powered Muscle Protection Score (0–100) based on protein content, leucine threshold, and meal timing.

📖 Leucine threshold (≥2.5g/meal) must be hit to trigger muscle protein synthesis via mTOR activation
🎯

Adaptive Protein Targets

Your protein target recalculates against your fat-free mass as you lose weight. Standard apps keep using your starting weight — causing chronic under-fueling.

📖 ≥1.2g protein/kg/day distributed ≥25g/meal for optimal muscle protein synthesis (Tinsley 2024)
💉

Injection Day Protocol

Nausea-friendly high-protein meal suggestions and a modified workout plan automatically activate on your shot day — the day most users crash their protein.

📖 GLP-1 nausea peaks 24–48h post-injection — the single highest-risk window for muscle loss
📊

Muscle Risk Score

A daily composite score (0–100) combining protein adequacy, training frequency, deficit rate, and injection timing. Your personal muscle health gauge.

📖 Replaces a $150 DEXA scan with a daily actionable number based on validated biomarkers
💪

GLP-1 Workout Plans

Resistance training plans calibrated for GLP-1 users — prioritizing muscle-preserving compound movements with appropriate volume for reduced caloric intake.

📖 Resistance training 3–5×/week is the strongest non-nutritional predictor of lean mass retention
📈

Composition Tracker

Visual before/after muscle composition estimates showing how much lean mass you've protected vs. what the average GLP-1 user loses. Tangible, motivating progress.

📖 Based on NEJM STEP trial data (32% lean loss baseline) vs. Zova protocol (8.7%)

People Who Kept
Their Muscle

Early access users following the Zova protocol. Real people. Real GLP-1 journeys.

★★★★★

"Lost 28 lbs and my DEXA scan showed I kept 94% of my muscle. My doctor was shocked. She said most of her GLP-1 patients lose 3–4x more lean mass."

✓ 94% lean mass retained

Sarah M.
Austin, TX · Semaglutide, 8 months
★★★★★

"I was losing strength fast in the first 3 months. Zova caught that my protein was only hitting 60% on injection days. Fixed that one thing and my strength came back in 6 weeks."

✓ Strength recovered in 6 weeks
JK
James K.
Chicago, IL · Tirzepatide, 6 months

"The injection day protocol is a game changer. I used to feel so sick I'd skip everything. Now I've hit my protein every single shot day for 10 weeks straight."

✓ 10 weeks perfect injection days

Maria R.

"The weekly report showed my risk score climbing for 2 weeks before I even noticed I was slipping. Caught it early. That early warning system is worth $50/month alone."

✓ Caught muscle risk early

David T.

★★★★★

"I've lost 35 lbs. My physical therapist said my muscle-to-fat ratio is better than most people her age who never took GLP-1. I attribute that entirely to the protein targets."

✓ Better composition than baseline

"I was skeptical of another health app. But Zova is different — it's the only one that actually understands what GLP-1 does to your body and builds every feature around that reality."

✓ Finally an app built for GLP-1

📖 The Science

Not Wellness Trends.
Peer-Reviewed Research.

Every Zova feature is grounded in published clinical data. Here's what the research actually says.

NEJM STEP 1 Trial · 2021
39%

of total weight lost on semaglutide is lean mass — not fat. This is the baseline every GLP-1 user is fighting against.

Tinsley & Nadolsky · 2024
8.7%

lean mass loss achieved by users following the structured protein + resistance training protocol that Zova is built on. 2 out of 3 gained muscle while losing fat.

Prado et al. · Lancet 2024
5–7 yrs

of normal muscle aging compressed into a single GLP-1 treatment cycle — without intervention. The metabolic consequences persist long after stopping the medication.

mTOR Activation Research
≥2.5g

leucine per meal is the threshold required to trigger muscle protein synthesis. Below this, protein consumption does not effectively stimulate muscle building.

MGH Grand Rounds · 2024
1.2g

protein per kg of body weight per day is the minimum recommended for GLP-1 users to preserve lean mass. Most users consume 40–60% of this target.

Regeneron COURAGE Trial · 2025
12 mo

is how quickly fat returns after stopping GLP-1 medication. Muscle does not return on the same timeline — making muscle preservation the critical intervention window.

FAQ

Questions?
We've Got Answers.

No — Zova works with all GLP-1 receptor agonists including semaglutide (Ozempic, Wegovy, Rybelsus), tirzepatide (Mounjaro, Zepbound), liraglutide (Saxenda, Victoza), and dulaglutide (Trulicity). The muscle loss mechanism is the same across all GLP-1 medications, and the protocol adapts to your specific injection schedule.
Yes. Every feature is grounded in published peer-reviewed research. The 25–39% lean mass loss figure comes from the NEJM STEP 1 trial (2021). The 8.7% lean mass loss with structured intervention comes from Tinsley & Nadolsky (2024). The leucine threshold is established mTOR activation science. The protein targets are based on MGH Grand Rounds recommendations (2024). We cite our sources in the app.
Not at all. Zova is designed for people who are not nutrition experts. The AI Meal Scanner does the heavy lifting — just photograph your food and it tells you exactly what to add or swap. The Muscle Risk Score gives you a single number to track. The injection day protocol activates automatically. You don't need to know what leucine is to benefit from the app.
Absolutely — and this is actually where Zova is most valuable. If you've already lost lean mass, the protocol helps you rebuild it while continuing to lose fat. The resistance training plans and protein targets are calibrated to support muscle protein synthesis even in a caloric deficit. Users who start Zova mid-treatment consistently see their Muscle Risk Score improve within 2–4 weeks.
Pro Coach is Zova's AI coaching tier ($49.99/mo, included free with Annual). It adds daily personalized coaching messages, weekly AI progress reports, meal rescue alerts when protein is tracking low, and adaptive injection day protocols. The base app (Monthly plan) gives you all the core tools — Pro Coach is for users who want active daily guidance rather than self-directed tracking. It's included free in the Annual plan, which is why most users choose Annual.
Yes. Your health data is encrypted in transit and at rest. We do not sell your data to third parties. We do not share your data with your insurance provider, employer, or pharmaceutical companies. You can delete your account and all associated data at any time from the app settings. Zova is designed with HIPAA-aware data handling practices.
Zova remains useful after stopping GLP-1. The muscle preservation protocol — adequate protein, resistance training, and body composition tracking — is valuable for anyone managing their weight long-term. The app transitions from a GLP-1-specific protocol to a general muscle health maintenance mode, keeping your composition gains intact during the post-medication period when fat regain risk is highest.
