Which Fruit Is Good For Weight Loss?
If you're trying to lose weight in the UK, fruit can be a healthy choice — but not all fruits are equal when it comes to weight management. The best fruits for weight loss are those high in fibre, low in calories, and packed with nutrients that keep you feeling fuller for longer. This guide explains which fruits support weight loss, how to include them in a balanced diet, and how they fit into an overall weight management strategy alongside other lifestyle changes.

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.
The Best Fruits for Weight Loss
Berries are among the best fruits for weight loss. Strawberries, blueberries, raspberries, and blackberries are low in calories (around 32–52 kcal per 100g) and high in fibre, which helps you feel fuller for longer. They're also packed with antioxidants.
Apples contain pectin, a soluble fibre that slows digestion and supports satiety. A medium apple has around 95 kcal and provides approximately 4g of fibre — ideal for sustainable weight management.
Pears are similarly high in fibre (around 6g per medium fruit) and contain only about 101 kcal, making them excellent for weight loss when eaten with the skin.
Oranges and grapefruits are lower in calories (47 kcal and 41 kcal per 100g respectively) and high in vitamin C. Some research suggests grapefruit may support modest weight loss when part of a reduced-calorie diet.
Avoid or limit: dried fruits (dates, raisins) and tropical fruits (bananas, mangoes) tend to be higher in calories and natural sugars, though portion control matters more than elimination.

Weight Loss: Fruit Alone Won't Be Enough
Fruit is nutritious and can support weight loss, but it won't create weight loss on its own. The NHS recommends losing weight at a sustainable rate of around 0.5–1 kg per week, which requires a calorie deficit of approximately 500 kcal per day. This is achieved through a combination of balanced eating, increased physical activity, and lifestyle changes.
For many people, prescription weight loss medication alongside diet and exercise can be helpful. Medications like GLP-1 injections (including Mounjaro and Wegovy) work by reducing appetite and supporting feeling fuller — meaning you may naturally eat less without restriction. Use our free GLP-1 weight loss calculator to see projected weight loss outcomes at different doses. For personalised advice on your weight management plan, consult your GP or a qualified healthcare professional.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the best fruit to eat when trying to lose weight?
Berries (especially raspberries and blackberries) are excellent — they're very low in calories (32–52 kcal per 100g) and high in fibre, which supports satiety. Apples and pears are also superb choices because they contain pectin and soluble fibre that help you feel fuller longer.
How many calories are in common UK fruits?
A medium apple has around 95 kcal, a medium pear about 101 kcal, a medium banana approximately 105 kcal, a medium orange roughly 47 kcal per 100g, and a cup of raspberries just 64 kcal. Dried fruits like dates are much more calorie-dense (around 282 kcal per 100g) so portion control matters.
Should I avoid fruit entirely when losing weight?
No. Fruit is nutritious and supports sustainable weight loss. The fibre, vitamins, and minerals in fruit are important for health. The NHS recommends including fruit as part of a balanced diet. Portion size and overall calorie intake matter more than avoiding fruit entirely.
Can fruit help me lose weight faster than diet alone?
Fruit supports weight loss because it's filling and nutritious, but sustainable weight loss requires a calorie deficit. The NHS recommends losing 0.5–1 kg per week through balanced eating and activity. For many people, this is achievable with diet and exercise alone — some find prescription weight loss medication helpful alongside lifestyle changes.
What's the difference between Wegovy and Ozempic for weight loss?
Both contain semaglutide, but only Wegovy is licensed in the UK for weight management. Ozempic is licensed for type 2 diabetes (at lower doses) and is not approved for weight loss. Always use the licensed weight management version — Wegovy — prescribed following clinical assessment from a qualified healthcare professional.
