A person is classed as obese when their weight has increased to a point where it seriously endangers their health. Obesity is diagnosed when a person's Body Mass Index (BMI) exceeds 30. BMI is calculated by dividing weight in lbs or kilogrammes by height in feet and inches or metres squared. Use our health calculator to work out yours
What are the causes?
Obesity is normally caused by a combination of eating too much of the wrong types of food and not doing enough exercise. We take a look at the contributing factors:
- Eat less and exercise more - it has long been the mantra for shedding those extra pounds. But now it seems that all the hard work may have been in vain. Traditionally, health practitioners have focused on diet and exercise - and a large dose of willpower - to treat the problem.
Lack of sleep could be partly to blame, they say in the International Journal of Obesity. In recent years, the average night's sleep has dropped from nine hours to just seven. Sleep deprivation alters levels of the hormones that regulate food intake and body fat and increase hunger and appetite.
- Those who take beta-blockers to control their blood pressure can often put on 3lb. Similarly, studies have shown that going on the Pill can add 11lb to a woman's weight.
Obesity related illnesses
Research has shown that being overweight or obese increases the risk of heart disease, diabetes, high blood pressure and cancer. Read more about the side-effects:
- Obesity is linked to an increased risk of bowel, kidney, oesophageal and stomach cancers, and also cancers of the womb and breast in post-menopausal women
- Diabetes is a serious condition, which can lead to blindness, kidney failure, heart disease, stroke and nerve damage that can cause amputation. Diabetes occurs when the body loses the ability to process blood sugar, leading to high levels which can damage organ
