Mounjaro Before and After Transformations

Weight loss medications like Mounjaro have helped countless people achieve their weight loss goals, improve their health and find new confidence. Here, our experts unpack how Mounjaro works, what to expect on your journey as well as real patient transformations to help you figure out if weight loss medication is right for you.

What is Mounjaro?

Mounjaro is a medication used to treat obesity. It is approved for people with a BMI of 30 and above, or those with a BMI of 27 and above who also have at least one weight-related health issue, such as prediabetes or high blood pressure. [1]

It is administered as a subcutaneous injection (into the fatty layer of tissue directly under the skin) once a week and should be used alongside a reduced-calorie diet and increased physical activity.

It contains the active ingredient tirzepatide, which mimics the actions of two naturally occurring hormones in your gut: glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP).

How Mounjaro Works for Weight Loss

The Mechanism: Regulating Blood Sugar

Mounjaro regulates blood sugar through:

• Boosting insulin release - Mounjaro helps your body release more insulin after a meal. Insulin is a hormone that lowers your blood sugar.
• Lowering glucagon release - Glucagon is a hormone that raises blood sugar when you’re not eating. Mounjaro lowers its release to keep blood sugar balanced.
• Slowing digestion - Mounjaro slows down how quickly food leaves your stomach. This helps control how fast sugar enters your blood, stopping sudden spikes in blood sugar. [2]

Impact on Appetite and Food Choices

Mounjaro also acts on areas of the brain that control appetite. By reducing hunger, it helps people to eat less which can lead to weight loss. Additionally, Mounjaro has been shown to reduce ‘food noise’ - which is the constant mental preoccupation with food. [3]

So, it's done wonders,” says Zion.

Plus, when it comes to continuing her weight loss journey Zion feels hopeful because she knows she’s only just getting started. “It honestly really has made me feel like I can definitely move goal posts and it makes me feel like I'm definitely going to be able to get to my goal… and I just didn't think that was ever possible before.”
