What Prescribers Commonly Consider Before Prescribing Mounjaro
Because Mounjaro is a prescription-only medicine, there is no single universal set of rules that applies everywhere — criteria differ depending on your country, your healthcare system, and your individual clinical picture. That said, prescribers across many settings tend to evaluate similar factors.
BMI and Weight-Related Health Conditions
In many countries, guidance for medicines in this class suggests they may be considered for adults with a BMI above a certain threshold — commonly around 30 kg/m² or above, or a lower threshold (often around 27 kg/m²) when weight-related health conditions such as type 2 diabetes, high blood pressure, or raised cholesterol are present. These figures are illustrative of common frameworks; your own prescriber's criteria may differ. Always rely on the guidance you have received directly.
Calorie and Lifestyle Context
Mounjaro is typically prescribed alongside dietary and lifestyle changes, not instead of them. Prescribers often expect people to be working toward appropriate calorie intake and activity levels as part of their programme. There is no fixed universal calorie requirement attached to the prescription itself, but many people find that understanding their calorie and protein needs helps them make the most of the appetite changes the medicine can bring. You can read more about the broader context of managing your Mounjaro journey on our overview page.
Conditions That May Affect Suitability
Certain medical histories may mean Mounjaro is not suitable, including a personal or family history of specific thyroid conditions, a history of pancreatitis, or pregnancy. This is not an exhaustive list — your prescriber will have reviewed your full history. According to NHS guidance, Mounjaro is not currently licensed for use in people under 18.
Not for Everyone
Suitability is always an individual clinical judgement. If you have questions about whether Mounjaro is right for you, or whether your current dose remains appropriate, those conversations belong with your prescriber or doctor — not with a tracking app or online article. You might also find it useful to read community perspectives on Mounjaro forums and user experiences to understand how others have approached these conversations.

Tracking the right four numbers — weight, waist, protein and dose — turns a noisy chart into a clear story. That's the loop GLP-1 users keep coming back for.
AI Meal Tracking. Built for GLP 1 Appetites.
Point your camera at any meal and let our AI do the rest. Breakfast, doses, weight, mood all tracked in seconds.
Tracking Your Progress Once You Are Prescribed
Once you are prescribed Mounjaro and begin your journey, staying consistent and informed is where a companion app can genuinely help. GLP Trackr is built specifically for people already on Mounjaro or Wegovy — it does not prescribe, dispense, or advise on suitability, but it does help you make the most of the journey ahead.
The most relevant feature for this stage is the daily check-in and weight tracking: logging your weight, energy, mood, and food-noise score each morning gives you a running record of how your body is responding over time. That data can be genuinely useful to bring to your next prescriber appointment — especially if you want to discuss progress, any side effects, or next steps.
If you are also thinking about calorie and protein intake — which many prescribers encourage alongside Mounjaro — the AI photo food scan makes logging meals quick even when appetite is low. Point your phone camera at a meal and GLP Trackr estimates calories, protein, and macros instantly. You can also note that Mounjaro is an injectable, not a tablet, which sometimes surprises people new to the medicine.
GLP Trackr helps you record your journey so you can have better-informed conversations with the clinician who knows your history. It is not a substitute for their advice, and any questions about whether you meet requirements, or whether the medicine remains right for you, should always go to your prescriber or doctor.
