💉 Built for GLP-1 Users

Your protocol is working.
Vela makes sure you're working with it.

Semaglutide and tirzepatide change everything about how your body processes food, burns fat, and builds lean mass. No standard health app was built for this metabolic reality. Vela was.

The Problem No One Talks About

GLP-1 medications are powerful.
The intelligence layer around them isn't built yet.

Your wearable tracks your body. Your prescriber manages your dose. But nobody is synthesizing the daily metabolic reality of what your protocol is doing — and telling you what to do about it every morning.

25–40%
of GLP-1 weight loss can come from lean muscle mass — not just fat
Lean Mass Loss Is the Silent Risk
GLP-1 medications suppress appetite powerfully. But reduced eating, without strategic protein prioritization, accelerates muscle loss. Most users don't see it until they're months in. Vela tracks body composition signals and flags protein deficits before they compound.
⚡
Appetite suppression means you have to be intentional about what you do eat
Less Appetite, Same Nutritional Requirements
GLP-1 users often eat 600–1,000 fewer calories per day. The nutritional requirements don't drop by the same amount. Protein, micronutrients, and hydration needs stay high — while appetite is suppressed. Vela monitors this gap and flags it every morning.
Fasting Windows Change on Protocol
Fasting windows that worked before GLP-1 can be too aggressive during active dosing — particularly when nausea is present or when lean mass preservation is the priority. Vela calibrates your fasting recommendations to your protocol week and biometric signals.
Side Effects Correlate With Inputs Nobody Tracks
Nausea, fatigue, and GI distress often correlate with specific foods, meal timing, training intensity, and hydration. Without logging this data intelligently, patterns are invisible. Vela's wellness logging captures it all — and the intelligence layer finds the correlations.
Vela's GLP-1 Intelligence

Six intelligence systems built specifically for your protocol.

Every morning, Vela synthesizes your biometrics, your logged inputs, and your protocol status into a brief that understands what GLP-1 does to your metabolism — not just what your body generally does.

1
Lean Mass Preservation Intelligence
Protein tracking · body composition signals · anti-catabolism alerts
›
GLP-1 medications are highly effective at reducing caloric intake. The risk is that without strategic protein prioritization, the body enters a catabolic state — burning lean muscle alongside fat. This happens silently and is difficult to reverse.

Vela monitors your daily protein intake against your body weight, tracks the lag between protein deficit days and HRV/recovery decline, and flags early warning patterns before lean mass loss compounds. When you're in deficit territory, the brief tells you before your next injection, not after three months on the scale.
"Protein at 98g yesterday — 67g below your GLP-1 adjusted target of 165g. This is day 3 of a deficit pattern. Lean mass preservation is at risk. Break your fast with 40g+ protein today. Prioritize eggs, Greek yogurt, or a protein shake before anything else."
WHAT VELA TRACKS
✓
Daily protein vs. GLP-1 adjusted target — your target adjusts to account for appetite suppression and lean mass risk
✓
Protein deficit streak counter — 3+ consecutive days under target triggers priority alert
✓
HRV × protein lag correlation — Vela finds the connection between your protein intake and recovery quality
✓
Training load × protein availability — if you trained yesterday and protein was low, brief flags muscle recovery risk
2
Protocol-Calibrated Fasting Windows
Injection week awareness · nausea signal · metabolic phase adjustment
›
Standard intermittent fasting logic doesn't account for GLP-1 pharmacokinetics. In the 2–3 days after injection, appetite suppression peaks and nausea risk is highest — this is often the worst window for an extended fast. Conversely, days 5–7 post-injection (before the next dose) can be optimal for a longer fasting window.

Vela knows your injection schedule, tracks your nausea and side-effect logs, and adjusts fasting recommendations accordingly. Your fasting brief is calibrated to your protocol — not a generic 16:8 recommendation.
"Day 2 post-injection — semaglutide peak window. Nausea logged yesterday. Shorten fasting window today to 12 hours maximum. Break fast with easily digestible protein. Save your extended fast for Day 5–6 when tolerance is higher."
WHAT VELA TRACKS
✓
Injection day logging — voice log "semaglutide 0.5mg" and Vela maps your pharmacokinetic window
✓
Nausea pattern tracking — log side effects via voice, Vela correlates to meal timing and fasting length
✓
Week-of-cycle fasting calibration — fasting window recommendation changes dynamically based on where you are in your injection cycle
✓
Ketosis estimation with protocol context — fasting-driven ketosis factored against GLP-1 metabolic state
3
Side Effect Intelligence
Nausea correlation · GI tracking · fatigue patterns · input-to-symptom mapping
›
GLP-1 side effects — nausea, fatigue, GI distress — are real and variable. What many users don't know is that these symptoms often correlate with specific inputs: fatty foods eaten too close to injection, high-sugar meals in the peak window, training too intensely in the first 48 hours, or insufficient hydration.

Without logging and pattern analysis, these correlations are invisible. Vela's lag correlation engine maps your wellness logs against your symptom reports and surfaces the patterns — so you can modify inputs instead of just managing symptoms.
"Nausea logged on 4 of your last 6 injection days. Pattern: fat intake >40g in the 3 hours before injection. Today is injection day. Keep fat intake minimal until 2 hours post-injection. Your tolerance windows are mapped."
WHAT VELA TRACKS
✓
Nausea voice logging — "feeling nauseous, about a six" → timestamped, correlated to recent inputs
✓
Lag correlation engine — finds what you ate or did 2–6 hours before symptoms appeared
✓
Fatigue signal separation — distinguishes GLP-1 fatigue from training fatigue via HRV + recovery data
✓
Hydration tracking — GLP-1 users have elevated dehydration risk; water logging + alerts integrated
4
Training on Protocol
Resistance training priority · caloric deficit training · recovery calibration
›
Training on GLP-1 requires a different calculus than training in a normal metabolic state. Resistance training becomes a non-negotiable — it's the primary lever for lean mass preservation. But training intensity must be calibrated against caloric availability, fasting window depth, and injection cycle timing.

Vela synthesizes your wearable training data against your nutrition logs and protocol status to deliver training directives specific to your GLP-1 metabolic reality — not generic HRV-based recovery advice.
"Recovery is solid at 71. But you're in a 400-calorie deficit and haven't hit protein in two days. Training hard today increases catabolism risk. Resistance work only — compound lifts, 45 minutes max. No cardio today. Fuel first."
WHAT VELA TRACKS
✓
Caloric availability + training load — checks if you have adequate fuel for the intensity planned
✓
Resistance vs. cardio directives — prioritizes resistance training for lean mass, adjusts cardio by protocol week
✓
Post-workout protein window — brief flags optimal protein timing after resistance training
✓
Cross-device training data — WHOOP strain + Garmin load + Apple Watch HR zones all factored
5
Dose Escalation Tracking
Injection log · dose history · titration milestones · pattern visibility
›
GLP-1 protocols involve dose escalation — typically every 4 weeks. Each dose change brings a reset in symptom and tolerance patterns. What worked at 0.5mg may not work at 1.0mg. Vela logs your full injection history and automatically flags the behavioral adjustments that typically accompany dose increases.

Over time, your Vela history becomes a personal pharmacological record — correlating dose levels with biometric outcomes, symptom tolerance, and body composition changes.
"You escalated to 1.0mg semaglutide 8 days ago. Based on your 0.5mg history, expect peak side effect window to shift 12–18 hours later at this dose. Your current nausea pattern is consistent with escalation adjustment. Typical resolution by day 14."
WHAT VELA TRACKS
✓
Full injection history — date, dose, compound, injection site if logged
✓
Dose escalation milestones — auto-detected from log pattern, behavioral adjustment flagged
✓
Biometric correlation by dose level — HRV, sleep quality, and recovery score patterns by dose over time
✓
Coach visibility — your trainer and dietitian see your full protocol alongside your biometrics in one view

Peptide Protocol Integration
BPC-157 · TB-500 · CJC-1295 · Ipamorelin · protocol stacking
›
Many GLP-1 users combine their protocol with peptide stacks — BPC-157 for tissue repair and gut health, TB-500 for injury recovery, CJC-1295 / Ipamorelin for growth hormone support. These aren't tracked by any standard health app.

Vela's wellness logging accepts all of these via voice — "BPC-157, 250mcg subcutaneous" — and tracks them in your protocol log alongside GLP-1 injections. The intelligence layer includes peptide timing in its daily directive.
PEPTIDES VELA TRACKS
✓
BPC-157 — tissue repair, gut health support. Dose, route, and timing logged.
✓
TB-500 (Thymosin Beta-4) — injury recovery and inflammation. Logged with training correlation.

Lean Mass Intelligence

Lose fat. Keep muscle.
Vela tracks the difference.

The goal of GLP-1 therapy isn't just weight loss — it's body composition improvement. Vela monitors the signals that indicate muscle preservation: protein consistency, training load, recovery quality, and HRV trend. When the picture shifts toward catabolism, the brief flags it immediately.

What Vela monitors: Daily protein intake vs. lean mass target · HRV trend vs. caloric deficit · Training load vs. protein availability · Recovery quality on low-intake days
Early warning system: 3+ consecutive days of protein deficit triggers a lean mass preservation alert in your brief — before the loss is measurable on the scale.

Real GLP-1 Morning Brief

This is the conversation
your protocol deserves.

A real example of what Vela delivers to a GLP-1 user — built from biometric data, voice logs, and protocol status. Not generic weight loss advice. Your protocol, decoded.

VELA MORNING BRIEF — GLP-1 Sarah · Week 6 of Protocol · Mon Jun 8
Protocol:Semaglutide 0.5mg
Last injection:Yesterday 8:14pm
Cycle day:Day 1 (peak window)
Wearable:Oura Ring + Apple Watch
RECOVERY
HRV 54ms — within baseline. Oura readiness 71. Body temp nominal. Sleep 7h 8m, efficiency 86%. You're recovered.
PROTOCOL
Day 1 post-injection — semaglutide peak window. Appetite suppression will be highest today. Nausea risk elevated based on your history. Do not skip meals — prioritize protein even if appetite is low.
FASTING
Shorten fasting window today — 12 hours maximum. Day 1 post-injection is not the window for extended fasting. Extended fasting is optimal for Days 5–6. Break fast by 9am with a protein-first meal.
PROTEIN
Yesterday: 142g protein — 23g below your 165g GLP-1 target. This is Day 2 of a deficit. Protein preservation is your top priority today. Eggs + Greek yogurt before 10am. Chicken or fish at lunch. Do not let appetite suppression compromise your protein today.
TRAINING
Day 1 post-injection — keep training light. If you feel well by midday, 30 minutes resistance training only. No cardio — caloric availability is too low for cardio to be productive. Prioritize compound movements that signal muscle retention.
SIDE EFFECTS
Your pattern: mild nausea Days 1–2, typically morning. Eat small, protein-dense meals. Avoid high-fat foods until this evening. Keep ginger tea on hand. Your Day 3 nausea historically resolves — stay consistent.
PRIORITY
Protein before anything else. Short fast. Light resistance training if you feel up to it. Hydrate aggressively — GLP-1 peak days elevate dehydration risk. Your protocol is working. Protect the lean mass.
