How does mounjaro affect appetite – real stories from patients

Mounjaro (tirzepatide) has a powerful effect on appetite suppression, making it an effective medication for weight loss. Its impact on appetite is primarily due to its unique mechanism of action, which involves mimicking two important hormones in the body. In this article we will first look at the science of why and how it can suppress appetite. Once that has been covered we will look at real life examples of how the appetite suppression has been experienced by patients to help you give an insight what to expect should you be treated with mounjaro for weight loss.


Mounjaro mechanism of Action

Mounjaro works by imitating two gut hormones: GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide). These hormones play crucial roles in regulating blood sugar levels and appetite control. By activating receptors for these hormones, Mounjaro influences the gut-brain axis, which is responsible for appetite regulation and feelings of satiety.


Effects on Appetite

Increased Satiety

Mounjaro helps users feel full more quickly and for longer periods. It activates specific areas in the brain that signal fullness, leading to decreased food intake[1]. This increased sense of satiety can result in smaller meal portions and reduced overall calorie consumption.

Reduced Cravings

The medication has been shown to combat food cravings, particularly for unhealthy or high-calorie foods. This effect can make it easier for individuals to stick to a healthy eating plan and resist overeating.

Slowed Digestion

Mounjaro slows down the digestive process, which contributes to prolonged feelings of fullness after eating. This delayed gastric emptying can help reduce hunger between meals and decrease the frequency of snacking.

Pharmacist comments

On Appetite Suppression and Cravings:

Mounjaro has demonstrated remarkable effectiveness in suppressing appetite and reducing cravings for unhealthy foods like sugar and processed carbohydrates. Many patients describe experiencing 'food freedom,' allowing them to focus on smaller, healthier portions. However, it’s important for users to remain mindful of their nutritional intake to avoid deficiencies."*

On Side Effects and Usage Caution:

While Mounjaro is a game-changer for weight management, some users experience side effects such as nausea, constipation, and GERD, especially when starting or increasing the dosage. To maximize its benefits and minimize discomfort, I advise patients to start with the lowest dose, stay hydrated, and consult their healthcare provider about any persistent issues.
