THE PROTOCOL

Reset. Optimize.
Sustain.

Three phases, defined by clinical criteria rather than calendar dates. Lab monitoring, titration guidance, and graduation benchmarks at every stage — shaped by a decade of treating metabolic disease.

THE PROTOCOL

Establish Their
New Standard

Proto360 is a physician-designed, three-phase metabolic protocol that goes beyond weight loss. Each phase builds on the last to create durable physiological change.

PHASE 1

RESET

An aggressive but medically supervised metabolic intervention to break insulin resistance patterns and initiate meaningful weight reduction.

  • GLP-1 receptor agonist titration
  • Metabolic biomarker baseline
  • Structured nutrition protocol
  • Weekly clinical check-ins
PHASE 2

OPTIMIZE

Transition from acute intervention to metabolic optimization — refining medication, nutrition, and behavioral protocols for sustained improvement.

  • Medication dose optimization
  • Advanced metabolic testing
  • Behavioral pattern integration
  • Bi-weekly progress reviews
PHASE 3

SUSTAIN

Long-term metabolic maintenance designed to prevent regression. Ongoing monitoring ensures patients maintain their clinical gains.

  • Maintenance protocol design
  • Quarterly metabolic panels
  • Ongoing coaching support
  • Clinical decision framework
Phase Anatomy

Gated by criteria,
not by calendar.

Patients advance when their physiology says they are ready. Each phase carries defined entry conditions, a clinical focus, a monitoring cadence, and explicit graduation benchmarks.

Phase 01
Reset

Interrupt the drivers — insulin resistance, inflammatory load, glycemic volatility — and establish a stable, documented baseline.

Entry
Intake labs complete, comorbidities documented, medication reconciliation performed.
Clinical focus
Glycemic stability, nutritional adequacy, sleep and stress load.
Monitoring
Weekly weight and adherence capture; lab recheck at the configured interval.
Advance when
Baseline markers trending, adherence sustained, no unresolved adverse effects.
Phase 02
Optimize

Move toward target ranges across all five domains while building the behavioral capacity to hold them without clinical scaffolding.

Entry
Reset graduation criteria met and confirmed by the treating provider.
Clinical focus
Body composition, lipid and glycemic targets, progressive activity load.
Monitoring
Biweekly review, remote monitoring inputs, periodic labs.
Advance when
Targets met or plateaued within an acceptable range, with the patient self-managing core behaviors.
Phase 03
Sustain

Hold the gains at reduced clinical touch, and catch regression early enough that intervention is a conversation rather than a restart.

Entry
Optimize targets held across a defined stability window.
Clinical focus
Maintenance, medication step-down where clinically appropriate, relapse prevention.
Monitoring
Monthly check-ins, quarterly labs, automated flagging on regression.
Ongoing
Patients remain in Sustain with periodic review rather than graduating out of care.
Five-Domain Integration

Five domains,
one clinical picture.

Metabolic disease does not respect specialty boundaries. Proto360 treats five interacting domains as a single picture rather than five separate problems handed to five different people.

01
Metabolic

Glycemic control, insulin sensitivity, lipid profile, and hepatic markers. The core disease process everything else is measured against.

02
Body Composition

Weight, lean mass retention, and visceral adiposity. Tracked together because scale weight alone cannot distinguish healthy loss from wasting.

03
Nutrition

Intake quality, protein adequacy, micronutrient status, and supplementation — phase-matched rather than prescribed once at intake.

04
Movement & Capacity

Activity load, strength, cardiorespiratory capacity, and functional tolerance. Progressive, and deliberately protective of lean mass.

05
Behavioral & Recovery

Sleep, stress load, adherence patterns, and psychological readiness. The domain that most often explains why the other four stall.

Why it has to be all five

A gain in one domain at the expense of another is not progress. Scoring across all five is what separates a clinical protocol from a diet with a portal.

Pharmacotherapy

The medication is a tool,
not the protocol.

GLP-1 receptor agonists changed what is achievable in metabolic medicine. They also created a problem: patients who lose weight on the drug and regain it after stopping, often with worse body composition than they started.

Titration by tolerability

Dose escalation follows the patient's tolerability rather than a fixed ladder, with structured symptom capture between visits so decisions rest on recorded data instead of recall at the next appointment.

Lean mass protection from day one

Protein targets and progressive resistance loading run alongside pharmacotherapy from the first phase. This is the difference between losing fat and losing function, and it is the most common omission in drug-only programs.

The exit is planned at intake

Discontinuation is designed at the start, not improvised at month nine. The Sustain phase exists to make step-down survivable, with regression flagged early enough for the provider to intervene.

/ MEDICAL LEADERSHIP /

Built by Metabolic
Medicine Specialists

Proto360 was designed by physicians who have spent over a decade treating metabolic disease at one of the nation’s largest weight management organizations. Our founders are dual board-certified in Obesity Medicine and Emergency Medicine — bringing both clinical depth and operational intensity to every aspect of the protocol.

This isn’t a wellness trend adapted for clinical use. It’s a medical system built from thousands of real patient encounters, refined through evidence-based practice, and engineered to scale.

Evidence & Limits

What the evidence supports —
and what it doesn't.

Metabolic medicine has a credibility problem, and overclaiming is most of the reason. Here is how we talk about results, including the parts that are inconvenient.

What the protocol is built on

Established clinical literature on metabolic disease management, weight-management pharmacotherapy, resistance training for lean mass preservation, and behavioral adherence. The specific reference list belongs here and needs clinical sign-off before this page is published.

What we measure and report

Outcomes are captured at the practice level and rolled up. Any figure shown on this site reflects results observed within certified practices, over a defined window, for patients who completed the phase in question.

What we do not claim

Proto360 does not claim to cure metabolic disease, guarantee individual results, or substitute for clinical judgment. Outcomes vary with adherence, comorbidity burden, and concurrent pharmacotherapy.

How to audit it

Providers evaluating the protocol can request the full outcome methodology — cohort definitions, exclusion criteria, the reporting window, and how non-completers are counted. We would rather answer that question early than have it asked later.

A Real Medical
Difference

01

Physician Developed

Every aspect of Proto360 was designed by board-certified physicians with deep expertise in metabolic medicine — not adapted from consumer wellness trends.

02

Five-Domain Integration

Our protocol integrates pharmacotherapy, nutrition, behavior change, biomarker monitoring, and clinical decision support into one unified system.

03

Measurable Infrastructure

Built-in measurement at every stage. Track outcomes, demonstrate ROI, and make evidence-based adjustments throughout the patient journey.

Capacity, outcomes, and revenue without added risk.

Partner with Proto360 to bring clinical-grade metabolic care to your patients, employees, or practice — backed by a complete infrastructure that handles the complexity for you.
