I Tried the New Weight Loss Drug Mounjaro: Here’s What Happened

So you’ve probably heard about Ozempic, Wegovy, and now Mounjaro. These drugs are taking over the weight loss world. Mounjaro (tirzepatide) was originally for diabetes, but it got FDA approval for weight loss this year. I decided to try it for three months. Here’s my honest experience.

How It Works

Mounjaro targets two hormones: GLP-1 and GIP. Together, they slow down digestion, make you feel full, and reduce appetite. It’s a once-weekly injection. The starting dose is 2.5mg, and you titrate up. I started at 2.5mg for four weeks, then 5mg for the rest.

The First Month

The first week was weird. I wasn’t hungry at all. Like, I’d forget to eat. That sounds great, but it’s actually disorienting. I had to remind myself to eat small meals. Side effects: mild nausea and constipation. Nothing unbearable, but not pleasant. I lost 8 pounds in the first month. Mostly water weight, I think.

The Second Month

At 5mg, the appetite suppression was stronger. I started craving healthier foods—greens, lean protein. Junk food looked gross. I lost another 6 pounds. Energy levels were fine, but I felt a bit tired on injection day. The nausea got better after a couple days each week.

The Third Month

By now, I’d lost 18 pounds total. That’s about 1.5 pounds per week, which is steady. I felt in control of my eating for the first time in years. The constant food noise in my head? Quiet. It was liberating. But I also noticed some hair thinning—a known side effect from rapid weight loss. It’s not permanent.

The Downsides

It’s expensive. Without insurance, it’s about $1,000 a month. Some insurance covers it for diabetes, but for weight loss, you might need a prior authorization. Also, the long-term effects aren’t fully known. And if you stop, the weight often comes back. This is not a quick fix—it’s a tool.

Would I Recommend It?

If you have significant weight to lose and have struggled with diet and exercise, it’s worth talking to your doctor. It worked for me, but it’s not magic. You still need to eat well and move. It just makes it easier. I’m planning to stay on it for a few more months to reach my goal, then taper off. We’ll see what happens. It’s a journey.
