What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
UK Mounjaro Access Routes and Prescription Costs
NHS access: Mounjaro is available through specialist tier 3 weight management services following referral from your GP. However, NHS availability varies significantly by region, and waiting lists can extend several months to over a year in many areas. When available on the NHS, Mounjaro is dispensed without direct patient cost (standard prescription charge applies in England, or free in Wales/Scotland if eligible).
Private prescription route: You can access Mounjaro privately through a UK-licensed prescriber via online consultation. This typically costs £129–£250 per month depending on your dose and provider. The Mounjaro KwikPen contains four weekly doses, so costs reflect your titration level. Private prescribing offers faster access without NHS waiting lists — most consultations can be arranged within days. A licensed prescriber will assess your eligibility, review your health history, and issue a prescription if appropriate. All private providers must be GPhC-registered pharmacies.
Key eligibility requirement: You must have a BMI of 30 kg/m² or above, or BMI of 27–29.9 kg/m² with weight-related health conditions such as type 2 diabetes, high blood pressure, or sleep apnoea. Lower BMI thresholds (from 27.5 kg/m²) apply if you are of South Asian, Chinese, Black African, or Black Caribbean heritage.

Lunch Ideas and Managing Food Changes On Mounjaro Dose Titration
Many people find their appetite significantly reduced on Mounjaro, especially as your dose increases during titration. Early weeks (at 2.5–5 mg doses) may see minimal appetite change, but appetite suppression typically increases at 10 mg and beyond. Practical lunch ideas include: small portions of protein-rich foods (chicken, fish, tofu), well-tolerated vegetables (steamed broccoli, carrots, leafy greens), and simple carbohydrates like rice or pasta in reduced quantities.
Nausea is common, especially in early weeks or after dose increases. Bland, easy-to-digest lunches work better than rich, fatty, or spicy foods. Many people find success with soup-based lunches, as these provide nutrition in gentle form. Keep yourself hydrated and eat slowly. As your body adjusts, you may gradually tolerate a wider range of foods. Track your progress and appetite patterns using a food diary or our free progress tracker to identify which lunch options work best for your body.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How much does Mounjaro cost privately in the UK?
Private Mounjaro typically costs £129–£250 per month, depending on your dose tier. Starter doses (2.5–5 mg) are usually cheaper; higher maintenance doses (10–15 mg) cost more. Prices vary slightly between providers, so it's worth comparing. Most private providers offer discreet online ordering and home delivery.
Can I get Mounjaro free on the NHS in the UK?
Yes, Mounjaro is available on the NHS through specialist tier 3 weight management services following GP referral. However, availability varies significantly by region and waiting lists can be very long (months to over a year). When prescribed on the NHS, you pay only the standard prescription charge (£9.65 in England) or nothing if exempt.
How do I access Mounjaro privately in the UK?
Contact a GPhC-registered online pharmacy that offers Mounjaro consultations. You'll complete an online health questionnaire and have a consultation with a UK-licensed prescriber (usually within 24–48 hours). If approved, a prescription is issued and your KwikPen is delivered to your home, typically within 3–5 working days.
What is tirzepatide and how does it differ from semaglutide (Wegovy)?
Tirzepatide (Mounjaro) is a dual GIP and GLP-1 receptor agonist, whereas semaglutide (Wegovy) is a GLP-1 agonist only. Clinical trials showed tirzepatide may produce slightly higher average weight loss (up to 20.9% at maximum dose versus ~15% for semaglutide), but individual results vary. Both are prescription-only and require clinical assessment.
What should I eat for lunch while titrating Mounjaro doses?
Start with small portions of easily digestible foods: grilled chicken or fish, steamed vegetables, light soups, and simple carbohydrates. Avoid fatty, spicy, or heavy meals, especially in early weeks when nausea is common. As your body adjusts, you may tolerate a wider range of foods. Stay hydrated and eat slowly. Use our free GLP-1 weight loss calculator to track potential outcomes as you progress through your Mounjaro dose titration.
