What to Expect in Your First 30 Days on Semaglutide or Tirzepatide

July 10, 2025

Your GLP-1 Weight Loss Journey Begins Here

If you’re starting your weight loss journey with a GLP-1 medication like Semaglutide (Ozempic, Wegovy) or Tirzepatide (Mounjaro, Zepbound), the first 30 days can feel exciting, but also full of questions.

At Chronos Body Health & Wellness, we support thousands of patients through their GLP-1 weight loss journey with evidence-based care, physician oversight, and customized support. This blog walks you through what to expect in your first month, so you feel informed and empowered every step of the way.

Week 1: Starting the Lowest Dose

Your journey begins with the lowest available dose, carefully prescribed to help your body adjust and reduce the likelihood of side effects. While results vary from person to person, here’s what many patients experience:

You may notice:

  • Appetite starts to decrease within a few days
  • Feeling full quicker or less interested in food
  • Mild side effects such as nausea, fatigue, constipation, or slight bloating.

Chronos Tip: Hydration and protein-rich, balanced meals can help ease symptoms and support your early progress.

Week 2: Appetite Shift Becomes Clearer

As you continue on your GLP-1, you may begin to feel more in control around food. This is a major breakthrough for many patients who’ve struggled with:

  • Constant hunger
  • Emotional or stress eating
  • Late-night snacking or sugar cravings

This is also when modest weight loss (often 2–5 lbs) may begin to appear on the scale, depending on your body type, movement, and eating habits.

Week 3: More Energy, Fewer Cravings

By Week 3, many patients report:

  • Improved focus and energy
  • Steadier blood sugar and fewer crashes
  • Feeling more confident about their ability to make food choices
  • 5–10 lbs lost, depending on the individual

This is also the time we encourage you to build supportive routines around your progress. At Chronos, we offer personalized fitness programs and nutrition coaching to help you sustain and amplify your results.

Week 4: Momentum Builds

By the end of your first month on Semaglutide or Tirzepatide, you’ve likely experienced:

  • 5–15+ lbs of weight loss (depending on your starting point)
  • A major shift in your hunger patterns and portion sizes
  • Improved relationship with food


This is where confidence grows, and where some patients explore complementary treatments like:
