What is obesity and how is it linked to Cancer.

What is the second most common killer in the world other then cancer, obesity.

Obesity is caused by eating to much and moving to little.

If you consume high amounts of energy, particularly fat and sugars, but don’t burn off the energy through exercise and physical activity, much of the surplus energy will be stored by the body as fat.

There are many ways in which a person’s health in relation to their weight can be classified, but the most widely used method is body mass index (BMI).

BMI is a measure of whether you’re a healthy weight for your height. You can use the BMI Healthy weight calculator to work out your score.

For most adults, a BMI of:

  • 18.5 to 24.9 means you’re a healthy weight
  • 25 to 29.9 means you’re overweight
  • 30 to 39.9 means you’re obese
  • 40 or above means you’re severely obese

BMI isn’t used to definitively diagnose obesity because people who are very muscular sometimes have a high BMI without excess fat.

But for most people, BMI is a useful indication of whether they’re a healthy weight, overweight or obese.

A better measure of excess fat is waist circumference, which can be used as an additional measure in people who are overweight (with a BMI of 25 to 29.9) or moderately obese (with a BMI of 30 to 34.9).

Generally, men with a waist circumference of 94cm (37in) or more and women with a waist circumference of 80cm (about 31.5in) or more are more likely to develop obesity-related health problems.

Obesity doesn’t happen overnight. It develops gradually over time, as a result of poor diet and lifestyle choices, such as:

  • eating large amounts of processed or fast food – that’s high in fat and sugar
  • drinking too much alcohol – alcohol contains a lot of calories, and people who drink heavily are often overweight
  • eating out a lot – you may be tempted to also have a starter or dessert in a restaurant, and the food can be higher in fat and sugar
  • eating larger portions than you need – you may be encouraged to eat too much if your friends or relatives are also eating large portions
  • drinking too many sugary drinks – including soft drinks and fruit juice
  • comfort eating – if you have low self-esteem or feel depressed, you may eat to make yourself feel better

Unhealthy eating habits tend to run in families. You may learn bad eating habits from your parents when you’re young and continue them into adulthood.

Obesity is on track to overtake smoking as the single biggest cause of preventable cancer according to a Cancer Research UK report.

The charity expects that within 17 years around 23,000 cases of cancers in women (9% of the total) could be caused by excess weight and about 25,000 (10%) by smoking.

If the projected trends continue, obesity as a cause of cancer in women will overtake smoking by 2043, the report says.

The figures for men are different as men are more likely to smoke and to get tobacco-related cancers. The gap between obesity and smoking as causes of cancer is expected to close much later than in woman.

While more males than females are overweight, obesity has a greater effect on women as some of the most common obesity-related cancers predominantly affect them, such as breast and womb cancers.

Cancer Research UK is launching a UK-wide campaign to increase awareness of the links between obesity and cancer. Being overweight as an adult increases the risk of 13 different types of cancer, including breast, bowel and kidney, yet just one in seven people in the UK are aware of the link.

Obesity can be combated but you have to have a plan.

Firstly look at your nutrition and replace high fat foods with more healthier options. Cut your calories but not to drastically and make time for exercise. This is the key to a better you.
