What is BMI???
October 12th 2006 00:09
Ok today I figured I would start adding some facts about obesity and nutrition to this blog. By the way if you think I use the word fat a lot, it is because that is how I feel, fat and ugly. Not over weight, that’s too nice a phase and not obese because that is just wrong. All information below was found at the World Health Organisation’s (W.H.O.) web page; it has lots of interesting information.
Obesity and overweight3
“Obesity and overweight pose a major risk for serious diet-related chronic diseases, including type 2 diabetes, cardiovascular disease, hypertension and stroke, and certain forms of cancer. The health consequences range from increased risk of premature death, to serious chronic conditions that reduce the overall quality of life.
The prevalence of overweight and obesity is commonly assessed by using body mass index (BMI), defined as the weight in kilograms divided by the square of the height in metres (kg/m2 ). A BMI over 25 kg/m2 is defined as overweight, and a BMI of over 30 kg/m2 as obese.
The more life-threatening problems fall into four main areas: CVD problems; conditions associated with insulin resistance such as type 2 diabetes; certain types of cancers, especially the hormonally related and large-bowel cancers; and gallbladder disease. The likelihood of developing Type 2 diabetes and hypertension rises steeply with increasing body fatness. Confined to older adults for most of the 20th century, this disease now affects obese children even before puberty. Approximately 85% of people with diabetes are type 2, and of these, 90% are obese or overweight.
Raised BMI also increases the risks of cancer of the breast, colon, prostrate, endometrium, kidney and gallbladder. Chronic overweight and obesity contribute significantly to osteoarthritis, a major cause of disability in adults. In the analyses carried out for World Health Report 2002, approximately 58% of diabetes and 21% of ischaemic heart disease and 8-42% of certain cancers globally were attributable to a BMI above 21 kg/m2.
What can we do about it?
Promoting healthy behaviours to encourage, motivate and enable individuals to lose weight by:
- eating more fruit and vegetables, as well as nuts and whole grains;
- engaging in daily moderate physical activity for at least 30 minutes;
- cutting the amount of fatty, sugary foods in the diet;
- moving from saturated animal-based fats to unsaturated vegetable-oil based fats”
I have calculated my current Body Mass Index (BMI) at 32.2 ……..
Calculation:
Your height in meters multiplied by itself, gives you the square so:
1.7 x 1.7 = 2.89
Now divide your weight by the figure above so:
93.0  2.89 = 32.1799
……. this means according to the W.H.O., I am obese (my doctor was right). So for me to reduce my BMI to 24, which is just below the overweight zone……………
Calculation:
Your height squared multiplied by the BMI which you want, so:
2.89 x 24 = 69.36
…………….I need to weigh 69kgs. I was pretty close with a goal of 70kgs! I will adjust my goal to 69kgs.
