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.
How Weight Loss Food Delivery Services Work
Weight loss food delivery services typically offer pre-portioned, nutritionally balanced meals sent to your home on a weekly or fortnightly basis. Most services allow you to choose from a menu of options, and meals are designed to fit within a specific calorie target—usually between 1,200 and 2,000 calories per day depending on your weight management goals.
- Meals are portion-controlled to help create a calorie deficit without constant calorie counting
- Services often provide nutritionist-designed recipes aligned with UK dietary guidance
- No shopping or meal preparation required—convenience can increase adherence
- Most UK services use locally sourced ingredients where possible
- Flexibility to pause or adjust meal selections weekly
These services are particularly useful if you struggle with meal planning or find cooking time-consuming. However, they work best as part of a broader weight management UK approach that includes physical activity and behavioural change, rather than as a standalone solution.

Weight Loss Food Delivery vs Other Weight Management Options
Food delivery services are one tool among many weight loss approaches in the UK. Some people combine them with prescription weight loss medication such as GLP-1 injections (Mounjaro or Wegovy), which work alongside dietary changes to support weight loss. Others use them with NHS weight loss programmes or self-directed calorie reduction.
The NHS recommends losing weight at a rate of 0.5 to 1 kg per week for sustainable results. Food delivery services can help achieve this by removing cooking barriers, but they don't address appetite regulation or metabolic factors the way prescription weight loss medication does. Your GP can advise whether a food delivery service, medication, or a combination approach is most suitable for your personal circumstances.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Do weight loss food delivery services really help you lose weight?
Yes—if they help you maintain a calorie deficit. Studies show that structured meal services improve adherence to reduced-calorie diets. However, weight loss depends on overall calorie intake. You must still eat fewer calories than you burn. The benefit is convenience and portion control, not the food itself being "special."
Are weight loss food delivery services available on the NHS?
No. NHS weight loss support includes tier 1 services (self-help tools, digital apps), tier 2 programmes (GP-led behaviour change), and tier 3 specialist services. Commercial food delivery services are private and paid for out of pocket. You can use them alongside NHS support.
Can I use a food delivery service if I'm taking Mounjaro or Wegovy?
Yes. In fact, many people combine prescription weight loss medication with structured meal services for maximum support. GLP-1 medications reduce appetite, while meal services provide structure and convenience. Always inform your prescriber about other weight management tools you're using.
How much do weight loss food delivery services cost in the UK?
Costs vary widely—typically £25 to £50 per day depending on the service and meal choices. This equates to £175 to £350 per week. Some services offer discounts for longer commitments. Compare the cost against your current food spending to determine true value.
Should I use a food delivery service instead of making my own meals?
Not necessarily. Home cooking gives you more control and is usually cheaper. Food delivery services are best for people who lack time, find meal planning difficult, or need external structure to maintain calorie goals. Use whichever approach you'll sustain long-term alongside physical activity and behaviour change.
