Mounjaro: a new step in GLP-1 treatment

Starting a new treatment for weight loss can be an exciting step—especially when it involves something new like GLP-1 medication. Gaining a better understanding of how these medications work, what results to expect, and potential side effects can bring peace of mind. In this blog, you’ll learn more about Mounjaro, one of the GLP-1 medications used for people dealing with obesity. 

What is Mounjaro?

Mounjaro, with the active ingredient tirzepatide, is an injectable medication. What sets Mounjaro apart from other GLP-1 treatments is that it works on two receptors: GLP-1 and GIP. Both are hormones that influence your appetite, blood sugar regulation, and fat metabolism. This dual action leads to a more powerful and longer-lasting effect than traditional GLP-1 medications like semaglutide (known from Ozempic and Wegovy).

Why is Mounjaro more expensive than other GLP-1 medications?

The cost of Mounjaro is higher than other GLP-1 medications, which naturally raises questions. There are three main reasons for this higher price:

1. Innovative dual receptor activation

Mounjaro targets both the GLP-1 and GIP receptors. This combined approach is new and allows the drug not only to suppress appetite, but also to improve insulin sensitivity and stimulate fat burning. This added complexity makes the medication harder to develop—but also more effective, which is reflected in its price.

2. Limited availability and high global demand

Since Mounjaro is still relatively new, production capacity is limited. At the same time, global demand for effective weight loss medications has skyrocketed, pushing prices up. At Goodweigh, we work with a trusted Dutch pharmacy to ensure safe and legal medication—no counterfeits or black-market products. Safety always comes first.

How does Mounjaro work?

Mounjaro helps your body naturally reduce appetite and process food more efficiently. It does this in several ways:

1. Delayed gastric emptying

One of the key effects of Mounjaro is that it slows down how quickly your stomach empties. Food stays in your stomach longer, helping you feel full for longer. This makes it easier to eat less without constantly feeling hungry.

2. Blood sugar regulation

Mounjaro stimulates the release of insulin when you eat, while also inhibiting the hormone glucagon, which normally raises your blood sugar. As a result, your blood sugar levels remain more stable, helping you avoid energy highs and lows.

3. Appetite suppression

Mounjaro acts on areas in the brain that control hunger and satiety, reducing appetite. Many people notice they have less urge to snack or overeat, even when facing emotional triggers.

You always start with a low dose to let your body adjust gradually. The dose is then increased step by step, depending on your personal response. This gradual approach helps reduce the risk of side effects like nausea, bloating or fatigue. At Goodweigh, this process is guided step-by-step in consultation with a Dutch doctor.

Why healthy eating remains important

It’s essential to understand that Mounjaro isn’t a magic solution. It supports you, but doesn’t do the work alone. A healthy diet remains a key factor for long-term results.

1. Nutrition enhances Mounjaro’s effects

Eating well helps the medication work with your body rather than against it. High-fiber foods, proteins and healthy fats keep you feeling fuller for longer—amplifying Mounjaro’s appetite-suppressing effect.

2. Healthy food prevents deficiencies and complaints

Eating less means you’ll naturally consume fewer nutrients. By choosing vegetables, fruit, whole grains and healthy fats, you ensure your body still gets what it needs—even when eating less.

3. You build sustainable habits

Mounjaro helps you lose weight, but the ultimate goal is to maintain your new lifestyle even after you stop using the medication. Healthy eating is the key. It’s not a diet—it’s a lifestyle change that needs to stick long after Mounjaro is gone.
