Verbatim response from Claude

Weight Loss on GLP-1 Medications

Typical Results

  • Average loss: 15-20% of body weight over 12-18 months with the strongest options
  • Most people lose 1-2 lbs per week initially, slowing over time
  • Results vary significantly based on diet, activity, and individual response

Specific Medications (Fastest to Moderate)

Strongest options:

  • Tirzepatide (Zepbound/Mounjaro) – up to 20-22% body weight loss in trials; currently the most effective
  • Semaglutide (Wegovy/Ozempic) – approximately 15% body weight loss on average

Milder options:

  • Liraglutide (Saxenda) – around 5-8% weight loss

Is It Sustainable? Honestly, It's Complicated

⚠️ The catch: Studies show most people regain significant weight within 1-2 years of stopping the medication

For sustainability, consider:

  • Using the medication window to build lasting habits
  • Working with services like Calibrate or Found that pair medication with lifestyle coaching
  • Planning with your doctor about long-term use

Bottom Line

These drugs work remarkably well while taking them, but they're increasingly viewed as long-term or lifelong treatment, similar to blood pressure medication.
