If you’ve tried to lose weight for years with little to show for it, you’re not alone. Many of our patients come to The Woodlands Institute for Health & Wellness after diet after diet has failed them. For many, the missing piece was a weight loss plan that examined and addressed the root causes of stubborn weight, including hormones, blood sugar, and metabolism, and paired them with the right GLP-1 peptide options (e.g., semaglutide, tirzepatide).

This case study shows what real before-and-after results can look like for patients in our weight-loss program, along with what the research shows and how our specialists support each patient along the way.
What Are GLP-1 Peptides for Weight Loss?
GLP-1 peptides mimic a natural hormone your body releases after eating. They slow digestion so you feel full sooner and longer, reduce hunger and cravings, and help regulate blood sugar. At The Woodlands Institute for Health & Wellness, we offer GLP-1 peptide options (e.g., semaglutide, tirzepatide, etc), and our specialists help you decide which one fits your health history and goals.
- Semaglutide works through a single pathway (GLP-1) to reduce appetite and improve blood sugar control. Available as an injection.
- Tirzepatide activates two pathways (GLP-1 and GIP) for a broader metabolic effect. Available as an injection.
- Retatrutide is an investigational “triple agonist” that also activates the glucagon receptor to support fat burning. It is not yet FDA-approved and remains experimental. Available as an injection.
For a deeper side-by-side comparison, see our Semaglutide vs. Tirzepatide or Retatrutide guide, or explore our peptide treatments.
What the Research Shows
Clinical trials give a helpful baseline for what’s possible with GLP-1 peptides:
- In trials of semaglutide over about 68 weeks, patients lost an average of around 15% of their starting body weight.
- In trials of tirzepatide over about 72 weeks, patients lost an average of around 20%.
- In early phase 2 studies of retatrutide over about 48 weeks, patients lost an average of around 24%. (This is not yet FDA_approved)
Results vary from person to person. That’s exactly why we build each plan around the individual, not a template.
Peptides Transformation Case Study: 30+ Pounds Lost and Kept Off for Nearly Two Years
Before Peptides: This patient came to us struggling with hormone imbalance, elevated blood pressure, unstable blood sugar, and weight she couldn’t lose on her own.
The Plan: She started a personalized program with semaglutide, alongside hormone balancing and ongoing guidance from her provider.
After Peptides: She lost more than 30 pounds and has kept it off for nearly two years. Her blood pressure is down, her hormones are balanced, and her blood sugar is finally stable.
“Thanks to [The Woodlands Institute for Health & Wellness], I feel better now than I did in my 20s. My hormones are balanced, my blood pressure is down, I’ve lost over 30 pounds and kept it off for nearly two years, and my blood sugar is finally stable. I LOVE Dyvette my provider. She’s amazing. She truly listens and offers personal, thoughtful guidance, not a generic, one-size-fits-all plan. If you’re looking for real healing instead of temporary fixes, I highly recommend [The Woodlands Institute for Health & Wellness].”
