Verbatim response from Claude

Weight Loss on GLP-1 Medications

Typical Speed of Loss

  • First 3 months: Usually 1-2 lbs per week, sometimes faster initially
  • Months 3-12: Slower, more gradual loss as your body adjusts
  • Overall: Clinical trials show 15-22% total body weight loss over 68-72 weeks on the most effective options

Top Medications by Effectiveness

  • Ozempic/Wegovy (semaglutide) – The current gold standard; Wegovy is FDA-approved specifically for weight loss, averaging ~15% body weight loss
  • Zepbound (tirzepatide) – Newest and strongest option, showing up to 22% body weight loss in trials
  • Saxenda (liraglutide) – Older, less potent, still effective for some people

The Sustainability Question (Be Honest With Yourself)

  • Studies show most people regain weight after stopping the medication
  • It works best as a long-term or indefinite tool, not a short-term fix
  • Combining it with diet and exercise changes improves lasting results

Getting Access

  • Talk to your doctor or try services like Ro, Hims/Hers, or Found for telehealth prescriptions
  • Cost can be significant without insurance ($900-1,300/month)

Bottom line: Results can be dramatic, but they require ongoing commitment to the medication and lifestyle changes.
