Registered Nurse. Patient advocate. Someone who has lived the GLP-1 journey from the inside.

Marcia Cripe is a Registered Nurse licensed in Michigan since 2008 and co-founder of GLP-1 Logic, where she combines clinical experience, emerging research, and lived experience to help people better understand GLP-1 medications and the changes that come with them.

She earned her Associate Degree in Nursing (ADN) from Glen Oaks Community College in 2008 and has built her nursing career across multiple healthcare settings, including acute care, home health, wound care, skilled nursing, care management for patients 65 and older, and inpatient rehabilitation.

Today, Marcia works as an RN Intake Coordinator for an inpatient rehabilitation facility, helping evaluate patients transitioning into rehabilitation care and collaborating with interdisciplinary teams to determine appropriate care needs.

She co-authors GLP-1 Logic with her husband, Dan Cripe, RN, BSN.

Together, they created GLP-1 Logic to provide something they felt was missing: evidence-based information about GLP-1 medications that also acknowledges the real human experience of taking them.

Why I Write About GLP-1 Medications

My interest in GLP-1 medications began as a personal journey, but it quickly became much more than that.

After researching incretin therapies for months, I started tirzepatide on May 10, 2024. What followed was a transformation that affected far more than a number on a scale.

Over time, I experienced the changes many people are now asking about:

• The quieting of food noise
• Changes in appetite and food preferences
• The emotional experience of significant weight loss
• The physical changes that follow major weight loss
• The questions that arise after reaching new milestones

As a nurse, I was fascinated by what was happening biologically. As a person living through it, I understood why people had so many questions.

Dan and I found ourselves having conversations about GLP-1 medications constantly — explaining what we were learning, discussing emerging research, and helping others understand their own experiences.

GLP-1 Logic grew from those conversations.

My Approach to GLP-1 Information

My goal is simple:

Explain what the research shows. Be honest about what we do not know. Respect the person behind the medication.

GLP-1 medications represent one of the fastest-changing areas of medicine today. New studies, clinical trials, and questions are emerging constantly.

At GLP-1 Logic, I approach every topic through three lenses:

Evidence

Whenever possible, information is grounded in peer-reviewed research, clinical guidelines, regulatory information, and other reliable medical sources.

Clinical Perspective

My nursing background helps me interpret medical information through the lens of patient care, safety, and real-world experiences.

Lived Experience

Some topics involve personal observations and experiences. These are clearly identified as personal experience rather than medical evidence.

I believe trustworthy health information requires both accuracy and humility. If something is not yet known, I believe saying “we do not know yet” is the most responsible answer.

Areas I Write About

On GLP-1 Logic, I write about topics including:

• GLP-1 receptor agonists and how they work
• Appetite regulation, food noise, and reward pathways
• Medication dosing and side-effect management
• The experience of titration and adjustment
• Long-term maintenance after weight loss
• Body changes after significant weight loss
• Emerging therapies and the future of incretin medications

My focus is not only what these medications do, but what it feels like to live through the changes they create.

My Nursing Background

My clinical experience includes:

• Acute care nursing
• Home health nursing
• Wound care
• Skilled nursing
• Care management for older adults
• Inpatient rehabilitation

Each area of nursing has shaped how I approach health information.

Nursing has taught me that medical decisions are never just about lab values, medications, or diagnoses. They affect people’s daily lives, relationships, goals, fears, and expectations.

That perspective influences everything I write.
