Which One Works Faster?
If your goal is speed, Zepbound might have the edge.
Why Zepbound May Work Faster
- Dual-Hormone Action – ZepBound targets both GLP-1 and GIP receptors, which may increase metabolism and fat burning faster than Wegovy.
- Faster Appetite Suppression – Some users report losing weight within the first few weeks due to a stronger appetite-reducing effect.
- More Weight Loss in Clinical Trials – Studies show Zepbound users lost 22.5% of their body weight, compared to Wegovy’s 15% average.
💡 Pro Tip: While ZepBound may work faster for some, individual results vary. Some people experience stronger appetite suppression on Wegovy, leading to similar weight loss timelines.
How Long Until You See Weight Loss?
Please note that this is a general timeline. Everyone – and I mean everyone! – responds differently to these weight loss medications. We just wanted to give you a basic idea of what the latest studies are reporting so you and your doctor can decide what’s best for you.
Wegovy Timeline
✔ Weeks 1-4: Appetite suppression kicks in
✔ Weeks 4-8: Initial weight loss starts (mostly water weight)
✔ Weeks 8-12: Noticeable fat loss begins
✔ 3+ Months: Steady weight loss continues
ZepBound Timeline
✔ Weeks 1-2: Strong appetite suppression
✔ Weeks 3-6: Faster weight loss than Wegovy on average
✔ Weeks 6-8: Noticeable changes in body composition
✔ 3+ Months: Significant fat loss continues
Does the Dosage Matter?
Yes! Both medications use a gradual dose increase to minimize side effects.
- Wegovy (Semaglutide) starts at 0.25 mg and increases to 2.4 mg over 16-20 weeks.
- ZepBound (Tirzepatide) starts at 2.5 mg and increases up to 15 mg over 20 weeks.
Remember that these are completely different medications, so don’t compare the milligrams (mg) with each dosage. Just because Zepbound maxes out at 15 mg vs a max of 2.4 on Wegovy, doesn’t mean that it is six times stronger. It’s not. It’s just a different medication altogether.
💡 Pro Tip: If you tolerate dose increases well, you might reach full effect sooner. If side effects force a slower titration (i.e. moving up to the next higher dose), results may take longer. Please note that there is nothing wrong with with taking longer! Many people prefer to titrate very slowly to the next dose.
Wegovy vs Zepbound Side Effects: Are They Different?
Both medications can cause nausea, bloating, and digestive issues, especially in the beginning. However, ZepBound users sometimes experience stronger initial side effects due to its dual-hormone action.
Most common side effects for both:
✔ Nausea
✔ Diarrhea or constipation
✔ Fatigue
✔ Appetite changes
