Someone on Reddit said they switched from Wegovy (the 2.4 mg dose of semaglutide) to Zepbound (tirzepatide, 7.5 mg) and, while keeping roughly the same daily calories, lost 2.5 pounds in one month. It’s a single person’s experience posted online, not a controlled study. The claim is interesting but anecdotal — it’s one story, not proof that the drug switch will do the same for everyone. Semaglutide (Wegovy) and tirzepatide (Zepbound) are injectable prescription medicines used to treat obesity. Semaglutide is a mimic of a natural gut hormone that tells your brain you’re full and slows stomach emptying. Tirzepatide is a newer drug that acts like two gut hormones at once — it hits the GLP-1 receptor (like semaglutide) and also a GIP receptor — so it may affect appetite, insulin, and how the body handles nutrients in a slightly different way. Both are powerful appetite-suppressing drugs compared with older weight-loss medicines, but they are different molecules and can feel different to users. What this Reddit post actually shows is one person reporting their own response after switching medications. That’s useful as a personal data point but not scientific evidence. It doesn’t tell us whether the weight change was due to the drug itself, differences in water or sodium balance, small unnoticed changes in activity or calorie counting, or natural variability in weight. We also don’t know how long this effect will last. Clinical trials comparing the two drugs do show that tirzepatide tends to produce larger average weight loss than semaglutide in groups of people, but individual responses vary a lot. For a regular person, the practical takeaway is cautious curiosity. If someone is already on one of these drugs and thinking of switching, this anecdote suggests it’s possible to see further weight loss after a change — but it’s not guaranteed. People who are struggling with appetite or weight despite one medication might discuss switching with their doctor. Also, comparing doses and side effects, and considering cost and insurance coverage, are important real-world factors. There are important caveats and risks. These medicines require a prescription and medical supervision. They can cause nausea, diarrhea, constipation, abdominal pain, low blood sugar if used with diabetes meds, and other side effects. Long-term effects and differences between drugs are still being studied. Reddit posts don’t include medical histories, so they can’t tell you whether the person had other conditions or used other therapies. Don’t change or stop medications based on a single social-media story — talk with your clinician. Bottom line: One Reddit user reported a small extra weight loss after switching from semaglutide to tirzepatide, but that’s just an anecdote. Clinical comparisons suggest tirzepatide can lead to greater average weight loss, but decisions about switching should be made with a doctor and based on full medical context.
