What to Expect in Your First Month on Wegovy or Mounjaro

Starting the Journey

The first month on Wegovy or Mounjaro is about letting your body find its rhythm. For many people, it’s a blend of excitement and curiosity. You might notice small changes almost straight away; things like feeling full sooner, having less interest in snacks, or finding that you simply don’t crave as much food.

These are early signs the treatment is working, but everyone’s pace is slightly different. Don’t rush it. Think of the first few weeks as setting a foundation rather than chasing fast results.

Week One: Adjusting to the Medication

Your prescriber will start you on the lowest dose to give your body time to adapt. In this first week, some people experience a little nausea or bloating. It’s normal and usually fades on its own.

Try eating smaller meals and avoiding heavy foods. Soups, salads, and light proteins such as chicken or eggs are ideal. Remember, it’s not about eating less but eating smarter.

If you feel slightly tired or off balance, give yourself time to rest. The first week is about getting used to how your body feels on the medication.

Weeks Two and Three: Feeling the Change

Around the second week, many people begin noticing that their appetite naturally adjusts. You might eat slower without thinking about it. Food still tastes good, but the urgency to snack fades.

This is also when your confidence starts to grow. You’ll feel more in control of your habits, which can be empowering after years of struggling with diets that didn’t stick.

A little light activity, such as walking or yoga, can help your body settle and lift your energy. It also keeps digestion smooth, which makes the whole process feel more comfortable.

Week Four: Settling into Routine

By the fourth week, most people find the treatment fits naturally into their life. You’ll likely feel comfortable with your new appetite and have a better sense of which foods make you feel good.

If things are going well, your prescriber may suggest a dose increase soon. Don’t feel pressured to move quickly. The best results come from a slow, steady build-up that your body can handle easily.

Tips for a Smooth First Month

• Eat small, balanced meals instead of skipping food entirely.
• Stay hydrated throughout the day.
• Avoid rich or greasy foods if you feel queasy.
• Take gentle walks to help digestion.
• Track your progress — even small wins count.

You may also want to note how your clothes fit or how your energy changes. Numbers on a scale are only part of the picture.

The Bottom Line

The first month on Wegovy or Mounjaro is the beginning of a new rhythm. You’re learning how your body reacts, what meals work for you, and how it feels to eat intuitively again.

Take it one week at a time. Consistency matters far more than perfection.
