In short: Sustainable weight loss comes from small changes you can keep up for years, not weeks. Set a realistic goal (losing 5 to 10% of your body weight brings real health benefits), build meals around protein, fibre and vegetables, watch portions, move more in ways you enjoy, sleep well and get support when you need it. Quick-fix diets rarely last.

This guide, written by a Ready Health prescribing pharmacist in Standish, sets out ten practical, evidence-based tips for losing weight and keeping it off.

What does sustainable weight loss mean?

It means losing weight at a steady pace through habits that fit your life, so the weight stays off. The NHS suggests aiming for around 0.5 to 1kg (1 to 2lb) a week. Faster loss is possible with very restrictive plans, but it is harder to maintain and more likely to be regained.

10 tips for losing weight and keeping it off

1. Focus on lifestyle change, not a "diet"

Diets have a start and an end date; habits do not. Pick a few changes you could see yourself doing in a year's time, such as cooking at home more often, swapping sugary drinks for water, or walking after dinner.

2. Set realistic goals

Losing 5 to 10% of your starting weight can improve blood pressure, blood sugar and cholesterol. Break this into small milestones and add goals that are not about the scales, such as walking a certain distance or sleeping better.

3. Enjoy the foods you love, in sensible amounts

Banning favourite foods often backfires. Plan for treats in smaller portions and less often, so you do not feel deprived.

4. Practise mindful eating

Eat at a table without screens, slow down and stop when you feel comfortably full. It takes time for fullness signals to reach the brain.

5. Watch your portions

Using a smaller plate, filling half of it with vegetables or salad, and checking portion sizes on food labels are simple ways to reduce calories without feeling hungry.

6. Choose water over sugary drinks

The NHS recommends around 6 to 8 glasses of fluid a day. Water, milk and sugar-free drinks all count. Sugary drinks, fancy coffees and alcohol can add a surprising number of calories; keeping alcohol within the UK low-risk guideline of no more than 14 units a week helps both your weight and your health.

7. Include protein at each meal

Protein from foods such as eggs, fish, lean meat, beans, lentils, tofu and low-fat dairy helps you feel full and protects muscle while you lose weight.

8. Choose high-fibre foods

UK guidance recommends adults aim for 30g of fibre a day, but most people eat far less. Wholegrains, oats, beans, lentils, vegetables, fruit, nuts and seeds all help you feel fuller for longer and support gut health.

9. Find movement you enjoy

Aim for at least 150 minutes of moderate activity a week, such as brisk walking, cycling or swimming, plus muscle-strengthening activity on two days. The best exercise is the one you will keep doing, so try different options and build up gradually.

10. Be kind to yourself and get support

Setbacks are part of the process. Look at the overall trend rather than one bad day. Support from family, friends, a group or a health professional makes people more likely to stick with changes.

Why sleep and stress matter too

Short or poor sleep affects the hormones that control appetite and can increase cravings. Long-term stress has a similar effect. Most adults need 7 to 9 hours of sleep. Regular bedtimes, limiting caffeine later in the day and keeping screens out of the bedroom can help.

When should I get medical support?

Consider speaking to a clinician if:

you have tried to lose weight for a long time without success
you have a weight-related condition such as type 2 diabetes, high blood pressure or sleep apnoea
you think a medical condition or medicine may be affecting your weight
your relationship with food is causing you distress

A clinician can check for underlying causes and discuss all options. For some adults, prescription weight loss medicines may be considered alongside diet and activity changes, but only after a prescriber has assessed whether they are safe and suitable for you.

Frequently asked questions

How fast should I lose weight?

Around 0.5 to 1kg a week is realistic and safe for most adults.

What is the best diet for sustainable weight loss?

There is no single best diet. The one that works is a balanced approach you can maintain, based on the NHS Eatwell Guide.

How do I avoid regaining weight?

Keep the habits that helped you lose weight, stay active, weigh yourself regularly and act early if your weight starts to creep up.

Does drinking water help weight loss?

Swapping sugary drinks for water cuts calories, and staying hydrated can help you tell the difference between hunger and thirst.
