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 Medication Available In The UK
If you're looking to lose weight in the UK, several prescription weight loss medications are now available through the NHS and privately. These are designed to work alongside lifestyle changes, including improved nutrition and increased physical activity.
- Mounjaro (tirzepatide) — A dual GIP and GLP-1 receptor agonist. Clinical trials showed an average weight loss of 15–21% of body weight. Once-weekly injection.
- Wegovy (semaglutide) — A GLP-1 receptor agonist. Average weight loss of approximately 15% in clinical trials. Once-weekly injection.
- Saxenda (liraglutide) — A daily GLP-1 injection option. Approved for weight management in the UK.
You may be eligible if you have a BMI of 30 or above, or 27 or above with weight-related health conditions such as type 2 diabetes or high blood pressure. Individual results vary, and these medications work best alongside a reduced-calorie diet and physical activity. Our GLP-1 weight loss calculator can help you explore potential outcomes at different dose levels.

Getting Started: NHS vs Private Routes
NHS route: Request a referral to your local specialist tier 3 weight management service. Availability and waiting times vary significantly by region, but the NHS can prescribe these medications if you meet eligibility criteria.
Private route: Online consultations with UK-licensed prescribers are available without NHS referral. A clinical assessment is required to ensure the medication is safe and appropriate for you. Costs vary by dose and provider.
Your GP can advise which route suits your circumstances and whether you meet eligibility criteria. Using our BMI calculator can help you check your starting point and provide useful context for that conversation. Whether you choose medication support or focus on dietary changes like an Indian meal plan, combining approaches with lifestyle modification offers the best chance of sustainable weight loss.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Can Indian food help with weight loss?
Yes. Traditional Indian cuisine includes many naturally nutritious options like lentils, chickpeas, vegetables, and spices. These are rich in fibre and protein, which support satiety and stable blood sugar. Key strategies include controlling portion sizes, using less oil in cooking, choosing grilled or steamed options over fried, and limiting high-calorie sauces. Pair dietary changes with regular physical activity for best results.
What is the difference between Mounjaro and Wegovy?
Both are prescription-only injectable medications for weight management. Mounjaro (tirzepatide) is a dual GIP and GLP-1 receptor agonist, showing average weight loss of 15–21% in trials. Wegovy (semaglutide) is a single GLP-1 agonist, with average weight loss around 15%. Both require clinical assessment and are administered once weekly. Individual results vary significantly.
Who can access prescription weight loss medication on the NHS?
You may be eligible if you have a BMI of 30 or above, or 27–29.9 with weight-related health conditions (type 2 diabetes, high blood pressure, heart disease, or obstructive sleep apnoea). For South Asian, Chinese, Black African, or Black Caribbean adults, lower BMI thresholds apply. Eligibility assessment is done by a specialist weight management service. Your GP can refer you.
How quickly will I lose weight on prescription medication?
Individual results vary significantly. Clinical trials showed average weight loss of 15–21% over 68 weeks, but some people lose more, others less. Weight loss typically occurs gradually alongside a reduced-calorie diet and increased physical activity. These medications are not a substitute for lifestyle changes—they support your efforts when used together.
What if I don't qualify for NHS prescription weight loss support?
Private online prescribing services are available in the UK without NHS referral. You'll need a clinical assessment from a UK-licensed prescriber to ensure the medication is safe for you. Alternatively, focusing on dietary changes (like adapting your Indian meal plan), regular physical activity, and using tools like our progress tracker can support sustainable weight loss without medication.
