Obesity

When someone is obese, it means they have put on weight to the point that it could seriously endanger their health. This is caused by a combination of eating too many calories and not doing enough physical activity.Everyone needs to make sure they maintain a healthy weight. Levels of obesity have tripled in England since 1980, and childhood obesity is a major public health concern.
Currently, over half of women, and about two-thirds of men are either overweight or obese.
Being overweight or obese increases the risk of developing heart disease, Type 2 diabetes, high blood pressure and osteoarthritis.Obesity causes about 18 million sick days and 30,000 deaths a year in England alone (source: National Audit Office).  You can tell from your Body Mass Index, or BMI, whether you are overweight or obese. To work out your BMI use our BMI calculator.

Your BMI is calculated using the following equation:

Your weight in kilogrammes (kg) divided by your height in metres (m) squared

So a man who weighs 85kg and is 1.75m tall will have a BMI of 28. A body mass index over 25 is defined as overweight, and over 30 is defined as

What dietary advice is there?

To maintain a healthy weight, it's important to follow a balanced diet.

Physical activity has benefits not only for controlling body weight over the long term, but also in controlling appetite. It has beneficial effects on the heart and blood that help to prevent cardiovascular disease.

If you want to lose weight, it's important not to go on a 'crash diet' but to change how you eat and organise a new diet that you can keep to all the time (not just when you're trying to lose weight).

If you go back to eating more calories than you need, you will put the weight back on.

Try:

• trimming the fat off meat
• choosing low-fat varieties of dairy and other products
• increasing your intake of starchy foods instead of fatty ones
• eating less of sugary foods
• increasing your intake of a variety of fruit and vegetables (aim to eat at least five portions a day)

Sometimes certain medical conditions and drug treatments can cause weight gain. Ask your GP for advice if you are suddenly gaining weight for no apparent reason or if you are on medication.

If you would like advice about losing weight, talk to your GP or a dietitian.
