Obesity: What is Obesity? Are You Killing Yourself By Being Fat? Is Your Weight A Killer?

Obesity is a medical condition that describes an accumulation of excess body fat. The excess body fat is not merely a few pounds; indeed most obese people will carry in excess of 30 to 40 pounds more than their recommended weight. The increase of excess body fat is so excessive that an obese person may suffer a multitude of health problems which may cause premature death. Health problems include the following...

• increased risk of heart disease
• increased risk of a stroke
• type 2 diabetes
• breathing problems
• cancer
• osteoarthritis
• back problems
• painful joints
• gout
• high blood pressure
• gall bladder disease
• gall stones
• difficulty sleeping
• infertility

The term clinically obese describes a person with a body mass index (BMI) of over 30. The term morbidly obese describes a person with a BMI of over 40. The ideal BMI is between 18.5 and 25. Calculating the body fat content is also another way of clinically determining obesity.

Calculate your BMI with this formula

BMI = weight (Kg) ÷ height (m²)

Example: Based on a person weighing 55 Kg with a height of 1.65 m

BMI = 55 Kg ÷ (1.65 m × 1.65 m) = 55 Kg ÷ 2.72 = 20.2 (ideal)

Check out the graph below for an easier way to calculate an ideal weight in relation to height... remember to allow room for age, sex and build.

Obesity is caused by eating more calories than the body requires to function. The remainder calories are stored as fat. Evidence to support larger people eating little, yet susceptible to gaining weight is confined. Bigger people need more calories to function than smaller people.

The association with weight gain in relation to genes is constantly under speculation: while a bigger build may be gene related; obesity (if not medical) is caused from consuming more calories than the body requires. Endocrine disorders and certain medicines have been proved to cause weight gain, however the effects are too broad to provide adequate statistics world wide. There are extensive tests that can diagnose illnesses where obesity may be a side effect. Psychiatric illness may also be a probably cause or an additional aspect of obesity. Stress and depression are other factors that may contribute to weight gain.

Generally however the main cause of obesity boils down to a mathematical equation; calories = energy required to fuel the body. If the energy consumed exceeds the amount of fuel used; the energy is surplus and stored as fat.

If a person eats 3500 calories more then the required calories in one week they will gain a pound. If that person is already living a sedentary lifestyle they will gain at least 2 Ibs. Should this become routine a person would gain between 52 Ibs and 104 Ibs in one year. That one pound a week adds up to 3 stone and 10 Ibs a year; at 2 lbs a week the addition arrives at a majestic 7 stone 6 Ibs in weight.

Admittedly an extra 3500 calories seems like a lot of calories. In fact this amount is almost double the recommended daily amount of 2000 calories for women. However a little research shows that an extra 3500 calories doesn't stretch that far when fast food and sugary drinks are on the menu.

• a big mac meal averages 1,000 calories
• a whopper and a large soft drink will cost a whopping 800 calories
• 1/2 a large meat and cheese pizza with a large soft drink tops the calorie scale at 1200
• an average chicken burger is 500 calories

The above fatty treats quickly add up to an average of 3500 calories a week. An extra pound in weight. Eating like this, will see weight gain rocket in less then six months. The weight gain will soar another few notches if activity is at a minimum level.

Obesity Around The World

Obesity has drastically increased since the 1980's. In recent years according to the World Health Organisation one billion people are overweight in the world; 300 million being clinically obese. That means in actual fact there are more overweight people in the world today than there are starving people. Our world harbours more than 800 million starving people.

Countries like the United States, Mexico, The United Kingdom, Australia and Greece are among the fattest in the world. Obesity costs millions of pounds world wide. And the cost is going up.

Before the arrival of the 20 th century obesity was a rarity. What changed to encourage us to eat more and move less?

The introduction of modern machinery and household appliances has revolutionised our world. We don't have to walk anywhere or even take the stairs anymore. Hard labour has been replaced with machinery in practically all industries. Our homes are full of modern appliances from washing and drying our clothes to self clean ovens and ever gadget under the sun; juicers, slicers, mixers etc. Even mowing the lawn is a ride in the park these days.

Family entertainment has been reduced to TV and computer games. These days playing a game of football requires two players and a remote control instead of two teams and a football. The arrival of the phone followed by the mobile has completely changed the way we communicate. No more hopping over the wall to chat with a neighbour or walking down the street to a visit a family member. The Internet has our finger tips and wrists working out like crazy while the rest of our bodies morph into the Michelin Man.

Ready meals and buckets of junk food keep all the family happy. Quick and cheap food full of fat and salt. The introduction of processed and convenience foods not only challenged their fresh and healthy counterparts on price and sell by date but also added more sugar and salt to the average daily diet. Sugary foods and drinks are available in numerous quantities and buying bigger usually means paying less.

Portion sizes have gone through the roof. Eat all you want buffets are rampant and cost next to nothing. In fact some restaurants advertise 'Eat the house special (half a cow between two burger buns) and not only will you get it free, you get the T-shirt too'.

Can we really blame fast foods, modern appliances and the Internet for being fatter now than ever before? Is it really our fault that portion sizes are mammoth? Who can blame families with busy lives opting to watch TV rather than going out for a walk together?

Perhaps blame should belong to the individual; after all we make our own choices. Eating huge amounts of food and doing little or no exercise is surely a slippery slope.

Being clinically obese is a serious health issue. Losing weight can dramatically improve health and lifestyle.

There is help out there for those that seek it. Pills to reduce the appetite, operations to reduce the stomach volume, counseling and support from families, friends and medical personnel. Eating healthy and exercising regularly increases the metabolism, energy levels and self esteem.

Losing weight isn't easy! But, it will get easier with time. Make the right choices and live longer; surely there's no competition when it boils down to life or death. Visit your doctor; get help; make today the first day of the rest of your life.
