Do I need labs before starting GLP-1?

Yes. We use baseline A1c, fasting insulin, CMP, thyroid markers, and lipid markers to confirm fit and to track whether therapy is helping the right endpoints.

How do you prevent muscle loss while losing weight?

Protein floor, resistance training progression, and regular check-ins are non-negotiable. Dose escalation slows if adherence drops.

Can this protocol run without medication?

Yes for some members, but this specific stack is designed for medication-eligible cases and routes non-eligible members to labs plus coaching-first care.

Metabolic + Men's Health Lead - updated April 2026How we review

Best fit

Who this protocol is built for.

We screen eligibility before any prescription enters the conversation. Decline is treated as an outcome, not a failure.

Adults with BMI 30+ or 27+ with metabolic comorbidity
Members with elevated A1c, fasting insulin, or ApoB
People who already attempted diet-only approaches without durable results

Contraindications

Who should avoid this path.

These are hard stops. We route into a different protocol or refer out, rather than working around a contraindication.

Pregnancy, breastfeeding, or planned conception
Personal or family history of medullary thyroid carcinoma or MEN2
Active pancreatitis or severe gastroparesis

Execution

Phased protocol timeline.

Each phase has explicit entry criteria, actions, and exit conditions. The plan moves on data and tolerance, not a calendar.

Phase 01
Weeks 0-2
Eligibility and baseline
Confirm eligibility, contraindications, and baseline biomarkers before any prescription.
- Complete clinical intake and medication interaction screen
- Run baseline panel (A1c, fasting insulin, CMP, ApoB, CBC, TSH)
- Set protein, hydration, and resistance-training floor
Phase 02
Weeks 3-12
Dose ramp and tolerance
Titrate semaglutide or tirzepatide while actively managing GI tolerance and adherence.
- Escalate dose only after tolerance checks
- Use meal timing, fiber, and hydration protocol to reduce GI effects
- Adjust calorie floor to avoid excessive lean-mass loss
Phase 03
Weeks 13-24+
Stabilize and retain
Hold effective dose, retest markers, and transition toward long-run maintenance behavior.
- Recheck A1c, fasting insulin, ApoB, and liver panel
- Lock 3-4 resistance sessions weekly plus protein adherence
- Plan taper, hold, or continuation based on biomarker and symptom response

Expected outcomes

What should improve.

8-18% body-weight reduction over 6-12 months depending on baseline and adherence
Improved A1c and fasting insulin trend
Reduced appetite volatility with fewer rebound episodes

Risk picture

What we monitor closely.

Nausea, reflux, constipation, and dose-step intolerance
Potential lean-mass loss if protein and training are not protected
Medication discontinuation regain risk without maintenance plan

Monitoring cadence

How we track progress.

Symptom check every 2-4 weeks during titration
A1c, fasting insulin, CMP, ApoB at baseline and 12-16 weeks
Body composition trend and training adherence monthly
