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.
Prescription Weight Loss Options Available in the UK
For adults who need additional support beyond dietary changes, prescription weight loss medications are available in the UK. Three main options have been licensed by the MHRA for weight management:
- Mounjaro (tirzepatide) — a once-weekly injection that works by activating dual GIP and GLP-1 pathways. Clinical trials showed participants lost an average of 15–21% of their body weight, though individual results vary significantly.
- Wegovy (semaglutide) — a once-weekly GLP-1 injection. In clinical trials, adults using Wegovy alongside reduced-calorie diets lost around 15% of their body weight on average.
- Saxenda (liraglutide) — a once-daily GLP-1 injection offering another option for eligible adults.
All three are prescription-only medicines requiring clinical assessment. Eligibility typically includes a BMI of 30 or above, or BMI of 27–29.9 with weight-related health conditions like type 2 diabetes, high blood pressure, or sleep apnoea. Our free BMI calculator can help you check where you currently fall on the NHS scale.

NHS vs Private Access — How to Get Started
In the UK, there are two main routes to prescription weight loss medication: NHS specialist services and private prescribing. The NHS approach involves referral to a tier 3 weight management service through your GP, though waiting lists vary significantly by region and can be lengthy in many areas. Private online clinics offer faster access following a consultation with a UK-licensed prescriber, though costs typically range from £130–£320 per month depending on dose.
Whichever route you choose, prescription weight management works best alongside lifestyle changes — including breakfast choices. Your GP or prescriber can discuss which approach suits your circumstances. If you're curious about potential outcomes, our GLP-1 weight loss calculator can help estimate weight loss projections at different doses, giving you a clearer picture before you book a consultation.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Can breakfast recipes alone help me lose weight?
Nutritious breakfasts can support weight management by reducing hunger and cravings throughout the day. High-protein, high-fibre options are especially helpful. However, weight loss ultimately depends on overall calorie intake and energy expenditure. For significant weight loss results, most people benefit from combining dietary changes with increased physical activity. If you've tried diet and lifestyle changes without success, your GP can discuss whether prescription weight loss medication might be appropriate for you.
Who is eligible for prescription weight loss medication in the UK?
The NHS may prescribe weight loss medication for adults with a BMI of 30 or above, or BMI of 27–29.9 with weight-related health conditions (type 2 diabetes, hypertension, sleep apnoea, cardiovascular disease). Lower BMI thresholds apply for South Asian, Chinese, Black African, and Black Caribbean adults due to higher health risks at lower weights. Only a GP or specialist prescriber can assess your individual eligibility following a consultation.
What's the difference between Mounjaro and Wegovy?
Both are once-weekly injections, but they work slightly differently. Mounjaro is a dual GIP and GLP-1 agonist, whilst Wegovy is a GLP-1 agonist only. In clinical trials, Mounjaro showed slightly higher average weight loss (15–21% vs 15%), though individual results vary. Both require a prescription and clinical assessment. Your prescriber will help determine which is more suitable based on your medical history and preferences.
How long does it take to see weight loss results with these medications?
Weight loss with GLP-1 and GLP-1/GIP medications typically begins within the first few weeks, though individual timelines vary. Most people see noticeable changes over 3–6 months as doses are gradually increased. Results depend on adherence, dietary choices, physical activity, and individual metabolism. Your prescriber will monitor progress and adjust doses if needed. Use our free progress tracker to log your weight loss journey and see trends over time.
Can I use breakfast recipes and weight loss medication together?
Yes — prescription weight loss medications work best alongside healthy lifestyle choices, including nutritious meals. Many people find they naturally eat smaller portions and make better food choices while using these medications. Breakfast remains important for managing hunger and maintaining energy levels. Your GP or specialist can provide dietary guidance alongside medication. The combination of medication plus conscious food choices often produces the best sustainable results.
