Losing weight and keeping it off isn't easy, but it has many benefits.
You may only need to make small changes to your lifestyle to maintain a healthy weight.
Obesity is linked to serious health problems and increases the risk of type 2 diabetes, heart disease and cancers of the breast, colon and prostate.
Most people who are overweight can blame their excess weight on eating more calories than they burn.

Why your waistline matters
Many doctors now believe that when it comes to your health, your waist measurement is important.
While knowing your body mass index (BMI) is a good way to work out if you're overweight, it doesn't tell the whole story.
BMI is a measure of how healthy your weight is for your height. You can work out what your BMI is by using our BMI healthy weight calculator.
If you have a high BMI, you're likely to be carrying extra fat. But your health could be at greater risk depending on where you store that fat.
Having a large amount of tummy fat (compared to fat around your bottom or thighs) makes you more likely to develop diabetes and heart problems.
A healthy waist circumference for men is less than 94cm (37 inches), and for women it's less than 80cm (32 inches).
