My Personal Experience with Diet on Mounjaro
I use compounded tirzepatide through Coreage Rx (same active ingredient as Mounjaro), and the appetite suppression is NO JOKE. By day 3 on even the 2.5mg starting dose, I had to force myself to eat.
What worked for me:
- Making protein the FIRST thing I ate at every meal
- Completely avoiding fatty foods (learned this the hard way—instant nausea)
- Setting reminders to eat because I'd forget I was hungry
- Drinking water constantly throughout the day
- Eating very slowly and stopping at the first sign of fullness
Biggest mistakes:
- Eating fast food in week 2 (felt sick for 6+ hours)
- Not tracking protein initially (probably lost some muscle)
- Trying to eat my old portion sizes (very uncomfortable)
Once I figured out the right diet—high protein, low fat, small frequent meals—I lost 16 pounds in 10 weeks with minimal side effects.
Using Coreage Rx Instead of Brand-Name Mounjaro
Brand-name Mounjaro costs $1,000-1,200/month. I use compounded tirzepatide through Coreage Rx for 50-70% less. Same medication, same results, same dietary recommendations—just affordable.

How much should I eat on Mounjaro?
Let your appetite guide you. Most people naturally eat 800-1,500 calories daily on Mounjaro. The key is ensuring you get adequate protein (60-100g/day) and nutrients, not hitting specific calorie targets.
Why does fat cause worse nausea on Mounjaro than other GLP-1s?
Mounjaro (tirzepatide) slows stomach emptying even more than semaglutide-based drugs because it targets two hormones (GLP-1 and GIP). Fatty foods naturally take longer to digest, creating a double-whammy effect. Stick to lean proteins and low-fat options.
What if I'm eating too little on Mounjaro?
Some people eat as little as 600-800 calories daily. While the medication makes this feel normal, aim for at least 1,000 calories with sufficient protein. Consider protein shakes if you struggle to eat solid food. Consult your physician if concerned.
Can I eat carbs on Mounjaro?
Yes, but prioritize complex carbs in small portions (oatmeal, quinoa, sweet potatoes). Avoid refined carbs (white bread, pasta, sugary foods) as they provide empty calories and can spike blood sugar.
Should I take vitamins on Mounjaro?
Yes, consider a daily multivitamin since you're eating significantly less food. Consult your physician about supplementing protein, vitamin D, B12, iron, and calcium to prevent deficiencies.
