There’s no specific recommended Mounjaro diet plan. A healthy diet with Mounjaro generally consists of fresh fruits and vegetables, whole grains, and lean proteins. Avoiding foods high in saturated fat, added sugars, and sodium is also vital.

Mounjaro (tirzepatide) is a GLP-1/GIP receptor agonist. It’s approved by the Food and Drug Administration (FDA) for use with diet and exercise to help manage blood sugar levels in people with type 2 diabetes.

Weight loss is an off-label use of Mounjaro. (Off-label use is when a drug is prescribed to treat a condition other than those it’s approved for.) Another tirzepatide product, called Zepbound, has been recently approved by the FDA for weight loss. (Tirzepatide is the active ingredient in Mounjaro.)

It’s recommended that Mounjaro be used in combination with a healthy diet and exercise. But there’s no single set of guidelines for what you should eat while taking Mounjaro.

Every person taking Mounjaro is different. It’s important to work with your doctor to create an individualized diet plan that addresses your specific dietary needs.

Generally speaking, sticking to a healthy, balanced diet can help you maximize the effects of Mounjaro. This means focusing on foods in the following groups, according to the Dietary Guidelines for Americans.


Vegetables may be fresh, frozen, or canned and include the following:

If you’re taking Mounjaro for diabetes, consider focusing on non-starchy vegetables, as they have a lower carbohydrate content than other vegetable types.


Fruits may be fresh, frozen, canned, or dried. This group also includes 100% fruit juice. At least half of your daily fruit intake should be whole fruit. Examples of common fruits include berries, apples, bananas, citrus, and peaches.

The American Diabetes Association notes that the best fruit choices for people with diabetes are those that are fresh, frozen, or canned with no added sugars. The organization also notes that most fruits, except for melons, pineapple, and some dried fruits, have a low glycemic index.


At least half of your daily grain intake should be whole grains, such as brown rice, oats, and barley. This includes products made with whole grains, such as whole wheat bread.

Other types of grains are refined and include items such as white rice, or are included in products such as white bread and pasta. It’s generally recommended that you limit your intake of refined grains.


Healthy protein sources include products such as:

Approximately how long will it take to lose 25 pounds (lb) with Mounjaro?

Weight loss varies by individual, but drug study results can give us a general idea.

For example, a 2022 study of tirzepatide (the active ingredient in Mounjaro) prescribed for obesity included people with an average weight of 231 lb. After 18 months, participants on the lowest dosage lost an average of 15% (about 35 lb) of their starting body weight. Those on the highest dosage lost an average of 20.9% (about 48 lb) of their starting weight.

How many daily calories should I eat with Mounjaro?

It’s important to talk with your doctor about how many daily calories you should eat during treatment with Mounjaro. In studies of Mounjaro, participants ate a diet with a deficit of 500 calories per day. (This means they ate 500 fewer calories than they burned each day.)

How much protein do I need to eat with Mounjaro?

Currently, the recommended dietary allowance of protein is 0.8 grams (g) per kilogram (kg) of body weight. (One kg equals approximately 2.2 lb). So for an adult weighing 150 lb, that’s roughly 54 g of protein per day. Talk with your doctor about their protein recommendations before starting Mounjaro.

It’s best to focus on a healthy, balanced diet while taking Mounjaro. This includes a diet rich in fresh fruits and vegetables, whole grains, lean protein, and low fat dairy products.

To maximize the effects of Mounjaro, avoid foods that are high in saturated or trans fats, added sugars, and sodium. Individuals with diabetes may also want to avoid food items with a higher glycemic index.
