Start losing weight If you're overweight

If you're overweight, losing weight will bring you a range of important health benefits. The key to success? Making realistic changes to your diet and level of physical activity that can become a part of your daily routine.

Evidence shows that the best way to lose weight is to make long-term changes to diet and physical activity that result in a steady rate of weight loss. Aim to lose weight at around 0.5kg to 1kg a week (1lb to 2lb), until you achieve a healthy BMI

This guide can help you to start your journey towards a healthy weight. Once you’re on the way, there is lots of information and advice that can help you keep going in our Lose weight section.

Along the way, you can monitor changes in your body mass index (BMI) using our Healthy weight calculator.

Commit to change

Physical activity recommendations for adults

• Adults (19-64 years) should do 150 minutes every week
• Older adults (65+ years) should do 150 minutes every week

People who are overweight or obese should first aim to gradually build up to 150 minutes of moderate-intensity activity per week

Modern life can make it easy to eat and drink more than we realise and do little physical activity. The result is often weight gain.

To lose weight, we need to change our current habits. This means eating less – even when eating a healthy, balanced diet – and getting more active.

Drastic fad diets and exercise regimes that result in rapid weight loss are unlikely to work for long, because these kinds of lifestyle changes can’t be maintained. Once you stop the regime, you’re likely to return to old habits and regain weight.

Instead, choose diet and physical activity changes that you can make a part of your daily routine, and stick to for life.

Do today

You can take four actions today that will start your journey towards a healthy weight:

• If you haven’t already, check your BMI with our Healthy weight calculator. If your BMI is in the overweight range, aim to achieve a weight that puts your BMI in the healthy range. If it is in the obese range, aim to lose between 5% and 10% of your starting weight. Having lots of muscle may put your BMI in the unhealthy range, even if you have little body fat. However, this will not apply to most people.
• Now take the next snack you plan to have and swap it for something healthier. Many common snacks, such as sweets, chocolate, biscuits and crisps, are high in fat and sugar and supply calories that we don’t need. Today, swap your elevenses or mid-afternoon snack for a piece of fruit, a fruit bun or a slice of malt loaf with a low-fat spread. Aim to do the same every day: you’ve adopted your first weight loss habit.
• Try to swap drinks that are high in calories for drinks that are lower in fat and sugars. Swap a sugary fizzy drink for a sparkling water with a slice of lemon. Don't forget that alcohol is also high in calories, so cutting down could help you to control your weight.
• Next, find a way to fit just one extra walk into your day. Fast walking is a way to burn calories, and you can often fit it into your daily routine. You might walk to the shops during your lunch break, or get off the bus one stop early on the way home and walk the rest of the way. Commit to this and you’ve adopted your second long-term habit. Ideally, you should aim to walk 10,000 steps a day: it’s not as many as it sounds. Learn more in Walking for health.
• Last, think about your breakfast tomorrow morning. Can you make it healthier, using the foods you already have at home? Get ideas in Five healthy breakfasts.

Do this week

There are four actions you can take this week:

• First, plan a healthy weekly shop. Healthy, balanced meals are key to a healthy weight, and eating a balanced diet often starts with having the right foods at home. At the supermarket look out for fresh foods and healthier options. Stuck for ideas? See our Healthy recipes.
• Everyone likes a treat occasionally, like a pizza or a takeaway. So this week, swap your treat for a healthier, home-made alternative as you can make lower-calorie versions of many takeaway foods at home. If you do order in, choose healthier options: see Healthier takeaways.
• Next, commit to one more way to increase your level of physical activity. The right amount of physical activity for you depends on your age. It’s recommended that adults between 19 and 64 get at least 150 minutes of moderate-intensity aerobic physical activity – such as fast walking or cycling – per week, and you are likely to need more to lose weight. For more on how much activity to do and what counts as activity, see Physical activity guidelines for adults. You could try our Couch to 5K programme, which is designed to get just about anyone off the couch and running 5km in nine weeks. For more ideas see our Health and fitness section and our step-by-step exercise guides for beginners. 
• Last, identify this week’s danger zones. These are times when you might find yourself eating lots of  foods that are high in fat and sugar, perhaps because you are eating out or simply because you’re tired or stressed. Plan ahead, so that you can limit those foods. But don’t be too strict: an indulgence from time to time is fine. For more advice, see Diet danger zones.

Eight tips for healthy eating

Eating a healthy, balanced diet is an important part of maintaining good health, and can help you feel your best. It doesn't have to be difficult either. Just follow these eight diet tips to get started.

Download Losing weight: Getting started, a 12-week weight loss guide that combines advice on healthier eating and physical activity.

The key to a healthy diet is to do the following:

• Eat the right number ofcalories for how active you are, so that you balance the energy you consume with the energy you use. If you eat or drink too much, you’ll put on weight. If you eat and drink too little, you’ll lose weight. The average man needs around 2,500 calories a day. The average woman needs 2,000 calories. Most adults are eating more calories than they need, and should eat fewer calories.
• Eat a wide range of foods to ensure that you’re getting a balanced diet and that your body is receiving all the nutrients it needs.

Get started

The eatwell plate

• To help you get the right balance of the five main food groups, take a look at the eatwell plate (PDF, 120kb)
• To maintain a healthy diet, the eatwell plate shows you how much of what you eat should come from each food group

These practical tips cover the basics of healthy eating, and can help you make healthier choices:

Base your meals on starchy foods Starchy foods should make up around one third of the foods you eat. Starchy foods include potatoes, cereals, pasta, rice and bread. Choose wholegrain varieties when you can: they contain more fibre, and can make you feel full for longer. Most of us should eat more starchy foods: try to include at least one starchy food with each main meal. Some people think starchy foods are fattening, but gram for gram they contain fewer than half the calories of fat. Learn more in Starchy foods.

Eat lots of fruit and veg 
It’s recommended that we eat at least five portions of different types of fruit and veg a day. It’s easier than it sounds. A glass of 100% unsweetened fruit juice can count as one portion, and vegetables cooked into dishes also count. Why not chop a banana over your breakfast cereal, or swap your usual mid-morning snack for some dried fruit? Learn more in 5 A DAY.

Eat more fishFish is a good source of protein and contains many vitamins and minerals. Aim to eat at least two portions a week, including at least one portion of oily fish. Oily fish is high in omega-3 fats, which may help to prevent heart disease. You can choose from fresh, frozen and canned; but remember that canned and smoked fish can be high in salt. Oily fish include salmon, mackerel, trout, herring, fresh tuna, sardines and pilchards. Non-oily fish include haddock, plaice, coley, cod, tinned tuna, skate and hake. Anyone who regularly eats a lot of fish should try to choose as wide a variety as possible.

Cut down on saturated fat and sugarWe all need some fat in our diet. But it’s important to pay attention to the amount and type of fat we’re eating. There are two main types of fat: saturated and unsaturated. Too much saturated fat can increase the amount of cholesterol in the blood, which increases your risk of developing heart disease. Saturated fat is found in many foods, such as hard cheese, cakes, biscuits, sausages, cream, butter, lard and pies. Try to cut down, and choose foods that contain unsaturated rather than saturated fats, such as vegetable oils, oily fish and avocados. For a healthier choice, use a just a small amount of vegetable oil or reduced fat spread instead of butter, lard or ghee. When you're having meat, choose lean cuts and cut off any visible fat. Learn more, and get tips on cutting down, in Eat less saturated fat.

Most people in the UK eat and drink too much sugar. Sugary foods and drinks, including alcoholic drinks, are often high in calories, and could contribute to weight gain. They can also cause tooth decay, especially if eaten between meals. Cut down on sugary fizzy drinks, alcoholic drinks, cakes, biscuits and pastries, which contain added sugars: this is the kind of sugar we should be cutting down on rather than sugars that are found naturally in foods such as fruit and milk. Food labels can help: use them to check how much sugar foods contain. More than 15g of sugar per 100g means that the food is high in sugar. Learn more in Sugars and Understanding food labels.

Eat less salt
Even if you don’t add salt to your food, you may still be eating too much. About three-quarters of the salt we eat is already in the food we buy, such as breakfast cereals, soups, breads and sauces. Eating too much salt can raise your blood pressure. People with high blood pressure are more likely to develop heart disease or have a stroke. Use food labels to help you cut down. More than 1.5g of salt per 100g means the food is high in salt. Adults and children over 11 should eat no more than 6g of salt a day. Younger children should have even less. Learn more in Salt: the facts.

Get active and be a healthy weightEating a healthy, balanced diet plays an essential role in maintaining a healthy weight, which is an important part of overall good health. Being overweight or obese can lead to health conditions such as type 2 diabetes, certain cancers, heart disease and stroke. Being underweight could also affect your health. Check whether you’re a healthy weight by using ourHealthy weight calculator. Most adults need to lose weight, and need to eat fewer calories in order to do this. If you're trying to lose weight, aim to eat less and be more active. Eating a healthy, balanced diet will help: aim to cut down on foods that are high in fat and sugar, and eat plenty of fruit and vegetables. Don't forget that alcohol is also high in calories, so cutting down can help you to control your weight. You can find information and advice in Lose weight. If you’re underweight, see Underweight adults. If you're worried about your weight, ask your GP or a dietitian for advice. Physical activity can help you to maintain weight loss or be a healthy weight. Being active doesn’t have to mean hours at the gym: you can find ways to fit more activity into your daily life. For example, try getting off the bus one stop early on the way home from work, and walking. Being physically active may help reduce the risk of heart disease, stroke and type 2 diabetes. For more ideas, see Get active your way. After getting active, remember not to reward yourself with a treat that is high in calories. If you feel hungry after activity, choose foods or drinks that are lower in calories but still filling.

Don't get thirstyWe need to drink about 1.2 litres of fluid every day to stop us getting dehydrated. This is in addition to the fluid we get from the food we eat. All non-alcoholic drinks count, but water, milk and fruit juices are the most healthy. Try to avoid sugary soft and fizzy drinks that are high in added sugars and can be high in calories and bad for teeth. When the weather is warm, or when we get active, we may need more. Learn more in Drinks.

Don’t skip breakfast
Some people skip breakfast because they think it will help them lose weight. In fact, research shows that eating breakfast can help people control their weight. A healthy breakfast is an important part of a balanced diet, and provides some of the vitamins and minerals we need for good health. Wholemeal cereal, with fruit sliced over the top is a tasty and nutritious breakfast.
