Considering semaglutide or tirzepatide for weight loss? Knowing what to expect—and when—is the key to staying motivated and maximizing results. In this guide, we’ll break down the typical treatment timeline, show how GLP-1 medications work over time, and explain how to track success beyond just the number on the scale.

Key Takeaways

• GLP-1s work gradually, with results building over 8–16+ weeks

• The first month focuses on appetite reduction and adjusting to side effects

• Weight loss typically begins in month 2 and builds steadily

• Tolerability improves with slow dose increases

• Consistency and lifestyle changes enhance your results
  

What Are GLP-1 Medications?

GLP-1 medications like semaglutide (Wegovy®, Ozempic®) and tirzepatide (Mounjaro®, Zepbound®) mimic a natural hormone that regulates hunger, slows digestion, and helps you feel full longer.

These medications are FDA-approved for diabetes and chronic weight management and can lead to significant, sustainable weight loss when paired with healthy habits.


Your GLP-1 Journey: A Week-by-Week Timeline

Note: Always follow your provider’s instructions. Dosing should be personalized based on your tolerance and medical needs.

How Long Do GLP-1s Take to Work?

• Appetite suppression: within the first week

• Weight loss: usually begins around weeks 4–6

• Significant results: often seen by weeks 12–16

• Long-term success: steady, healthy weight loss of 1–2 lbs per week is typical
  

Why the Slow Start?

GLP-1 medications are titrated slowly to reduce side effects like nausea and fatigue. This slow-and-steady approach also helps your body adapt and build lasting habits that support weight loss for the long haul.

🔁 Weight loss is a marathon, not a sprint—and the GLP-1 journey is designed with your long-term success in mind.
