How to achieve a healthier weight through realistic, balanced eating habits that last.
Losing weight can sometimes feel like an uphill struggle. With so many diets, food trends and conflicting messages about nutrition, knowing where to start can be difficult.
Many people find themselves caught in a cycle of losing weight, regaining it and starting again. Often, this is because the approach they have followed is too restrictive or difficult to maintain alongside everyday life.
The key to successful weight management is not finding a quick fix. It is developing healthy habits that are realistic, enjoyable and sustainable.
As a registered dietitian, I believe that successful weight loss should be about more than the number on the scales. It should also support your overall health, energy levels, muscle strength and relationship with food.
Here are some practical, evidence-based ways to approach weight loss and maintain your progress.
Focus on sustainable changes, not quick fixes
Many popular diets promise rapid weight loss, but restrictive approaches can be difficult to maintain and may leave you feeling hungry, tired or deprived.
Very restrictive diets can also make it harder to meet your nutritional requirements.
The NHS recommends aiming for gradual weight loss, generally around 0.5–1kg (1–2lb) per week for adults for whom weight loss is appropriate. However, progress will vary between individuals, and slower weight loss can still be beneficial.
Rather than changing everything at once, start with one or two achievable goals.
For example:
Include vegetables with lunch and dinner.
Reduce sugary drinks.
Plan meals in advance.
Increase your daily walking.
Establish more regular meal patterns.
Small changes that become part of your everyday routine are often more successful than dramatic changes that only last a few weeks.
Build balanced meals that keep you satisfied
One of the most effective ways to support weight management is to focus on the balance and composition of your meals.
A balanced meal should provide protein, fibre-rich carbohydrates, vegetables or fruit and some healthy fats.
A useful starting point is to think about the following:
Protein: Chicken, fish, eggs, tofu, beans, lentils or yoghurt. Protein helps maintain muscle mass and contributes to feelings of fullness.
Vegetables and fruit: Provide fibre, vitamins and minerals, while adding volume to meals.
Fibre-rich carbohydrates: Choose oats, wholegrain bread, brown rice and wholemeal pasta to support digestive health and satisfaction.
Healthy fats: Include olive oil, nuts, seeds and avocado in appropriate portions.
You do not need to eliminate carbohydrates or fats to lose weight. Both have an important role in a balanced diet.
The aim is to find a balance that provides adequate nutrition while supporting your individual energy requirements.
Don't overlook protein
Protein is particularly important during weight loss.
When we lose weight, we can lose both fat and muscle. Maintaining adequate protein intake, alongside resistance exercise, can help preserve muscle mass.
Good sources include:
Eggs.
Fish and lean meat.
Greek yoghurt and cottage cheese.
Beans, lentils and chickpeas.
Tofu and soya products.
Try including a source of protein at each meal rather than consuming most of your protein in the evening.
Maintaining muscle is important not only for appearance but also for strength, mobility and metabolic health.
Understand portion sizes without becoming restrictive
Even when we eat nutritious foods, portion sizes can influence our overall energy intake.
However, portion control does not mean weighing every ingredient or avoiding foods you enjoy.
A few practical strategies include:
Use a balanced plate as a guide, filling around half with vegetables, a quarter with protein and a quarter with starchy carbohydrates.
Be mindful of portions of oils, dressings, cheese, nuts and other energy-dense foods.
Serve meals onto a plate rather than eating directly from packets.
Eat slowly and give yourself time to recognise when you feel comfortably satisfied.
Pay attention to hunger and fullness rather than feeling you must finish everything on your plate.
The aim is to develop awareness of your eating habits without becoming overly focused on food or calories.
Fibre: An important part of weight management
Fibre plays an important role in digestive health and can help us feel fuller for longer.
Foods naturally rich in fibre often require more chewing and take longer to eat, which can help support satisfaction after meals.
Good sources include:
Vegetables and fruit.
Oats and wholegrain cereals.
Wholemeal bread and brown rice.
Beans, lentils and chickpeas.
Nuts and seeds.
The UK recommendation for adults is around 30g of fibre each day.
Try including fibre-rich foods throughout the day and increase your intake gradually alongside adequate fluid.
Look beyond food: Sleep, stress and activity matter too
Weight management is influenced by much more than what we eat.
Sleep, stress, hormones, medication, medical conditions and physical activity can all affect appetite, eating behaviours and body weight.
Physical activity
Regular movement supports cardiovascular health, mood, fitness and weight management.
Aim to build activity into your everyday routine. This could include walking, cycling, swimming, gardening or attending exercise classes.
The UK Chief Medical Officers recommend at least 150 minutes of moderate-intensity activity each week for adults, alongside muscle-strengthening activities on at least two days.
Sleep
Poor sleep can influence appetite regulation and food choices. Aim for a consistent sleep routine and prioritise getting enough rest.
Stress
Stress can affect eating patterns, sometimes increasing appetite or encouraging emotional eating. Finding ways to manage stress, such as walking, relaxation or social activities, can support overall wellbeing.
Why does weight loss sometimes become more difficult?
Weight management is complex, and it is important to recognise that body weight is influenced by many factors.
As we lose weight, the body can adapt by reducing energy expenditure and increasing hunger signals. This can make maintaining weight loss challenging.
Other factors may include:
Menopause and hormonal changes.
Age-related changes in muscle mass.
Certain medications.
Sleep difficulties.
Stress and emotional wellbeing.
Underlying medical conditions.
Changes in activity levels and daily routines.
If you have been struggling with unexplained weight changes or finding weight management particularly difficult, discussing this with your GP can help identify whether further assessment is appropriate.
A personalised approach is often more helpful than simply reducing your food intake further.
How do you maintain weight loss long term?
Losing weight is one part of the process; maintaining that progress is another.
Once you reach a weight that is appropriate for your health and personal circumstances, the focus shifts towards finding an eating pattern and lifestyle that supports weight stability.
Some helpful strategies include:
Continue eating regular, balanced meals.
Maintain physical activity and strength training.
Keep protein and fibre-rich foods in your diet.
Be aware of changes in your routines and eating habits.
Avoid returning to restrictive dieting when your weight fluctuates.
Remember that occasional changes in weight are normal.
Consistency is more important than perfection. A healthy lifestyle needs to accommodate holidays, social occasions, busy working weeks and the occasional meal out.
How can a registered dietitian help?
Everyone's experience of weight management is different. Your medical history, lifestyle, nutritional requirements, preferences and previous experiences with dieting all need to be considered.
A registered dietitian can help by:
Assessing your current diet and nutritional requirements.
Identifying habits that may be affecting your weight.
Developing a personalised eating plan.
Supporting weight loss while maintaining muscle mass and nutritional adequacy.
Helping manage conditions such as type 2 diabetes, high cholesterol and high blood pressure.
Providing ongoing support and helping you navigate challenges.
Importantly, dietetic support is not about judgement or prescribing a one-size-fits-all diet. It is about helping you understand your body and develop an approach that works for you.
Final thoughts: Making weight loss sustainable
Successful weight management is not about eating perfectly, cutting out your favourite foods or following the latest diet trend.
It is about developing a balanced approach to eating, being physically active, looking after your wellbeing and making changes that you can maintain.
There is no single diet that works for everyone. Finding an approach that suits your lifestyle, nutritional needs and health goals is what matters most.
The best weight-loss plan is one that supports your health, allows you to enjoy food and is realistic enough to maintain for life.
