Ready to start? Let’s break down your path to a healthier you.
This guide covers the first 12 weeks and beyond, with tips to keep you on track. Results vary, but with dedication, you could lose up to 22.5% of your body weight in 72 weeks.
Weeks 1–4: Starting Your Journey
Your Mounjaro journey begins with a 2.5 mg dose injected weekly for four weeks. This low dose helps your body adjust. You might notice reduced appetite within days, as Mounjaro mimics hormones that signal fullness. Some see a 1% weekly weight loss (about 1–2 pounds), often due to water weight from lower calorie intake.
Common side effects like nausea or fatigue may pop up. To manage them:
- Eat smaller, balanced meals with lean proteins and veggies.
- Stay hydrated to ease nausea or constipation.
- Choose a consistent injection day (e.g., every Monday) to keep levels steady.
Don’t expect big results yet. Focus on building habits, like tracking meals in a food diary.
Week | Dose | Expected Weight Loss | Tips |
1–4 | 2.5 mg | 0–4% (1–2 lbs/week) | Hydrate, eat balanced meals, set reminders |
Weeks 5–8: Finding Your Rhythm
After four weeks, your doctor may increase your dose to 5 mg weekly. You’ll likely feel fuller for longer, making it easier to stick to a calorie deficit. Studies show an average 6% weight loss by week 8 for those combining Mounjaro with diet and exercise.
Side effects might return with the dose increase but often fade. Keep up healthy habits:
- Add light exercise, like 20-minute walks, to boost results.
- Use a weight loss tracker to monitor progress.
- Rotate injection sites (thigh, abdomen, or upper arm) to avoid irritation.
Feeling a plateau? Don’t worry—weight loss varies. Check in with your doctor if results stall.
Week | Dose | Expected Weight Loss | Tips |
5–8 | 5 mg | Up to 6% (3–6 lbs total) | Add exercise, track progress, rotate sites |
Weeks 9–12: Seeing Progress
By week 9, your dose may rise to 7.5 mg, depending on how you’re tolerating Mounjaro. You could see up to 8% weight loss by week 12. Consistency is key—stick to a balanced diet and regular movement. Clinical trials show Mounjaro users lose 16.1–23.6 kg (35–52 lbs) over 72 weeks, far outpacing placebos.
Non-scale victories shine here, like better energy or improved mood. To maximize results:
- Focus on nutrient-dense foods (think whole grains, fruits, and lean proteins).
- Try resistance exercises to preserve muscle mass.
- Connect with a support community, like Reddit’s r/Mounjaro, for motivation.
Week | Dose | Expected Weight Loss | Tips |
9–12 | 7.5 mg | Up to 8% (5–8 lbs total) | Focus on nutrition, add strength training |

Beyond Week 12: Long-Term Success
From week 13, your dose may increase to 10 mg or 15 mg, the maximum maintenance dose. Long-term commitment pays off—clinical data shows 20–22.5% weight loss after 72 weeks at 15 mg. If side effects are tough, you can stay at a lower dose that works for you.
Plateaus are normal. If weight loss slows, tweak your routine:
- Increase activity (e.g., 30-minute walks or light weights).
- Reassess your diet to avoid processed foods.
- Consult your doctor to optimize your dose.
Warning: Stopping Mounjaro can lead to weight regain. One study found a 14% weight regain after switching to a placebo. Keep up healthy habits to maintain results.
Tips for a Successful Mounjaro Journey
To make the most of Mounjaro, pair it with lifestyle changes. Here’s how:
- Eat well: Prioritize whole foods over sugary snacks. A balanced diet fuels fat loss.
- Move more: Aim for 150 minutes of weekly exercise, like brisk walking or yoga.
- Track progress: Use apps or journals to monitor weight, meals, and goals.
- Stay safe: Watch for rare side effects like severe abdominal pain (possible pancreatitis) and contact your doctor immediately if they occur.
Curious about eligibility? Mounjaro is typically prescribed for those with a BMI of 30+ (obese) or 27+ with weight-related health issues, like high blood pressure. Always consult a doctor before starting.
