Mounjaro Diet Plan: The Ultimate Guide to Eating Well

Last Updated: April 1, 2024

Are you considering taking Mounjaro? Or perhaps you’re already taking it and unsure what diet plan to follow for optimal results?

While there isn’t one specific Mounjaro diet plan for everyone, certain strategies can significantly enhance the effectiveness of Mounjaro in managing your blood sugar levels and weight. 

This guide aims to navigate you through the ideal Mounjaro diet plan and lifestyle practices to adopt to ensure your path towards better health is both sustainable and effective.

What is Mounjaro?

Mounjaro is a type 2 diabetes treatment that mimics the action of two hormones that your body naturally produces after you eat. These hormones are GLP-1 and GIP. 

It helps control blood sugar by making you feel fuller longer, slowing down how fast your stomach empties, helping your body release insulin to lower blood sugar, and telling your liver to release less sugar into your blood. 

This combination keeps blood sugar levels more stable, reducing spikes and dips.

It also regulates hunger levels, leading to a reduced appetite and possibly aiding in weight loss. 

They’re often grouped together, but Mounjaro is different from semaglutide (Ozempic and Wegovy) in that it’s a different drug called Tirzepatide.

Mounjaro Diet Plan

What kind of diet should you be on while taking Mounjaro?

Generally, a diet rich in vegetables, fruits, whole grains, legumes, nuts, seeds, low-fat dairy, and lean protein is best. 

Incorporating a balance of carbohydrates, healthy fats, and protein into every meal can support your blood sugar and weight loss goals while ensuring your body gets the nutrients it needs.

What To Eat on Mounjaro 

The best Mounjaro diet plan is one that’s focused on whole foods to give you all of your nutrition while minimizing unpleasant side effects. 

Below are some of the main food groups to include in your meals:

1. Lean Proteins

Protein is essential for maintaining muscle mass, especially when you’re in a calorie deficit. 

Many people find it difficult to meet their protein goals when taking these medications because of their reduced appetite. 

The goal should be to minimize muscle loss as much as possible. Losing weight from muscle can lower our metabolism and make long term weight maintenance more challenging.

If you’re not sure how much protein you need, a good goal to aim for is 1.2 grams per kilogram of your body weight (1). This ensures that you are getting enough to support your metabolic health. 

Healthy lean protein sources include:

  • Eggs
  • Fish
  • Skinless chicken breast
  • Turkey breast
  • Tofu and tempeh
  • Edamame
  • Greek yogurt
  • Beans and lentils
  • Cottage cheese

Aim to include a protein source with every meal and snack you eat. 

2. High Fiber Foods

Foods rich in fiber are considered complex carbohydrates and include certain foods like fruits, vegetables, and whole grains. They’re a necessary part of the diet for managing blood sugar and body weight. 

Fiber contributes to satiety, helping you feel fuller for longer, and reducing your overall calorie intake (2). It also helps lower blood sugar levels (3)

Fiber rich foods include:

  • Vegetables: Broccoli, brussels sprouts, potatoes, avocados, leafy greens
  • Fruits: Berries, apples, pears, kiwi 
  • Legumes: Beans, lentils, chickpeas
  • Whole grains: Quinoa, oats, barley, farro
  • Nuts and seeds: Flax seeds, chia seeds, pumpkin seeds, almonds, walnuts

3. Healthy Fats

Healthy fats provide us with fat soluble vitamins and make us feel fuller because they slow the digestion process. Not only that, but they provide us with heart healthy monounsaturated fats and omega-3s.

Here are some sources of healthy fats to include:

  • Avocados: Rich in monounsaturated fats and fiber, avocados can enhance the feeling of fullness and provide essential nutrients.
  • Nuts and Seeds: Almonds, walnuts, chia seeds, and flaxseeds are excellent sources of omega-3 fatty acids.
  • Olive Oil: A cornerstone of the Mediterranean diet, olive oil is high in monounsaturated fats and antioxidants.
  • Fatty Fish: Salmon, mackerel, tuna, and sardines are not only good sources of lean protein but also rich in omega-3 fatty acids, which are beneficial for heart and brain health.

Foods to Avoid on Mounjaro 

Below is a list of foods to limit from your Mounjaro diet plan for the best results.

High-Calorie, Low-Nutrient Foods

These foods contribute to weight gain without providing much nutrition. Examples include highly processed foods, fast food, baked goods, and alcoholic beverages. 

This doesn’t mean you can’t ever have them, but you’ll find yourself feeling better if the majority of your diet consists of whole, minimally processed foods. When you do eat these foods, do so mindfully to prevent overeating. 

Fatty/Fried Foods

While healthy fats are necessary, excess intake of them can lead to digestive discomfort. 

Because fat slows down digestion, and Mounjaro already causes food to move through your body more slowly, eating a large amount of fat at one sitting can cause things like nausea and abdominal pain. 

Fried foods are usually high in fat and not tolerated well. Limit fried foods, butter, and high-fat meat and dairy products. Focusing more on plant based fats and limiting unhealthy saturated fats can also have benefits for your heart health. 

Sugary Snacks and Beverages

Sugar-sweetened beverages and snacks can significantly increase calorie intake without satiating hunger. It’s best to limit them and choose sugar-free varieties when available.  

Managing Side Effects of Mounjaro

Like any medication, this medication has potential side effects. Some of the most common side effects include nausea, diarrhea, and constipation. 

Oftentimes, these symptoms are accompanied by a feeling of fullness, which can leave you feeling uncomfortable after eating only a few bites of food and ultimately lead to undereating.

While weight loss does require some level of calorie restriction, this consequence is not ideal as it may result in nutritional deficiencies, fatigue, and/or muscle loss.


1. Eat Smaller, More Frequent Meals

Large meals can exacerbate nausea by overloading the digestive system. Instead, aim for smaller, more manageable portions spread throughout the day.

Also, make sure each small meal is balanced, containing a mix of carbohydrates, proteins, and healthy fats to maintain energy levels and stabilize blood sugar, which can help in managing nausea. 

2. Avoid Fatty or Spicy Foods

Fatty, greasy, and heavily spiced foods can be harder to digest, potentially worsening nausea. Opt for bland, easy-to-digest foods such as:

  • Boiled or steamed vegetables.
  • Lean proteins like chicken or turkey.
  • Easy to digest carbohydrates, such as toast.

Sometimes, the temperature of food can affect nausea. Cold or room temperature meals might be more tolerable than hot meals, as they often have less aroma, which can trigger nausea.

3. Additional Tips to Manage Nausea

Ginger is a natural remedy that has been shown to reduce nausea. Consider adding ginger supplements or incorporating ginger into your diet.

And of course, It’s important to communicate with your healthcare provider about any side effects you’re experiencing, including nausea. 

They can offer additional strategies, adjust your medication dosage, or possibly prescribe anti-nausea medication to help manage symptoms more effectively. 

There are many strategies that can help mitigate discomfort so you don’t have to “live with it”. 


Because of the slowed digestion, constipation is a common side effect. Below are a few things you can focus on: 

1. Fiber

Fiber adds bulk to the stool and helps it move through the digestive system more quickly, which can alleviate and prevent constipation. If you don’t eat a high amount of fiber, gradually increasing your intake to 25-30+ grams per day can be beneficial. 

This can be achieved by incorporating a variety of fiber-rich foods such as:

  • Vegetables: Aim for a variety of colors and types, aiming for at least 2-3 cups per day.
  • Fruits: Include 2 cups of fruit per day, focusing on whole fruits for added fiber.
  • Whole Grains: Switch to whole grain options like quinoa, oats, and whole wheat products.
  • Legumes: Beans, lentils, and peas are excellent sources of fiber and protein.

2. Water

Adequate hydration is essential for preventing constipation. Water helps to soften the stool, making it easier to pass.

Drinking 8-10 glasses of water daily or half your body weight in ounces is generally recommended, but some people may benefit from even more depending on their climate and physical activity routine. 

3. Exercise

Regular physical activity helps stimulate intestinal movements, known as peristalsis, which moves stool through the digestive tract.

Engaging in daily movement, whether it’s walking, swimming, or cycling, can help reduce the time it takes food to move through the large intestine, thus reducing water absorption from the stool and making it easier to pass. 

Even simple activities like stretching or yoga can improve digestive health.

If the above lifestyle modifications are not sufficient to relieve constipation, medication may be necessary. 

Over-the-counter options include fiber supplements, stool softeners, and laxatives. Talk to your doctor about your symptoms so they can help you choose the right regimen for you. 

Other Lifestyle Changes 

Importance of Exercising Regularly

Combining a balanced diet with regular exercise can amplify weight loss results and improve blood sugar levels while you’re taking Mounjaro. 

Aim for at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity each week, along with muscle-strengthening exercises on 2 or more days a week, as recommended by health guidelines (4)

Strength training is particularly important when taking this medication because it helps prevent muscle loss and promotes fat loss as the primary target.

This not only helps to improve overall body composition but also has a positive impact on long-term health and your ability to keep the weight off. 

Setting Realistic Goals and Tracking Progress

One of the worst things we can do for ourselves is set unrealistic goals. Because when we don’t meet them, we’re destined to give up.

Establish achievable goals that ensure you can actually meet them considering your schedule and capabilities. Then monitor your progress by tracking your habits and make adjustments as you face challenges.

This way, you can navigate your journey with clarity and purpose. Because it’s a marathon, not a sprint, and patience and persistence are your best friends.

Tips for Success

Here are some additional things you can do to get the most out of your Mounjaro diet plan.

Stay Consistent with Medication and Lifestyle Changes

Consistency and adherence are key to seeing results. Stick with your medication schedule and maintain your diet and exercise plan.

Seek Support from a Registered Dietitian 

Relying solely on medication for weight loss doesn’t teach you much about sustainable healthy eating habits, how certain foods impact your blood sugars, improving your relationship with food, or making lasting lifestyle changes.

To get the most out of your medication, consider seeking the expertise of a Registered Dietitian (RD)

RDs are qualified nutrition experts who offer personalized guidance on how to eat for blood sugar control and weight loss, managing side effects, and ensuring your eating plan is sustainable and tailored to your needs.

Final Thoughts

The key to maximizing the benefits of Mounjaro lies in pairing it with the right diet—one that’s rich in whole foods, lean proteins, high-fiber foods, and healthy fats, while minimizing high-calorie, less nutritious foods. 

Consider working with a dietitian to create a diet plan that complements your medication regimen. This can help you navigate the side effects, enhance the medication’s benefits, and set you on a path toward achieving your health goals.

Embracing a diet and lifestyle that supports your treatment can transform the Mounjaro experience from merely managing symptoms to thriving. 

With patience, consistency, and the right guidance, the journey with Mounjaro can lead to significant, life-enhancing changes.
