What to Expect Your First Month on Semaglutide

Week 1: The Starting Dose (0.25mg)

Most people notice subtle appetite changes within 3-5 days of their first injection. It's not dramatic — more like the volume on background hunger turning down slightly. You might find yourself forgetting to snack or feeling satisfied with smaller portions.

Common experiences: Mild nausea (usually passes within a few days), slight fatigue, reduced interest in food between meals. Scale movement is typically 1-2 lbs, mostly water.

Week 2: Settling In

Side effects from the first injection usually fade. Your body is adjusting to the medication. Appetite suppression becomes more noticeable — you might catch yourself leaving food on your plate without thinking about it.

Tip: Focus on protein-rich meals. Even though you're eating less, hitting 80g+ protein daily helps preserve muscle mass.

Week 3: Finding Your Rhythm

By now you've established your injection day routine. Most people report that "food noise" — the constant background thinking about food — has quieted significantly. This is often described as the most life-changing aspect of the medication.

Weight loss: Typically 2-4 lbs total by this point. Don't worry if it's less — the starting dose is sub-therapeutic for weight loss.

Week 4: Preparing to Titrate

End of the first month. Average weight loss is 1-3% of starting body weight (3-8 lbs for a 250 lb person). You're about to step up to 0.5mg, which is where appetite suppression becomes more pronounced.

What to expect next: The dose increase may bring a brief return of nausea for 2-3 days. This is normal and temporary.

Key Takeaways

• The first month is about adjustment, not dramatic results
• Real weight loss acceleration happens at 0.5mg and above
• Side effects are usually mild and temporary
• Focus on protein and hydration from day one
• Don't compare your week 4 to someone else's week 20
