BMI : Body mass index is one of the most important indicators of obesity. It is also very easy to use. Just divide your weight (in kilograms) by the square of your height(in meters – which roughly equals your body’s surface) and you get your BMI. If you don’t use the SI as measurement units, than you should use the following scaling factors:

for multiply by 703, and

for multiply by 4.88.

In the history of medicine there have been many attempts to calculate the ideal weight of a person (e.g. Broca’s formula) but studies have shown that BMI is the most accurate and can yield consistent results when applied to random individuals of a population.

Easy to remember numbers you should keep your eyes on are 20-25-30. If your BMI goes well under 20 (actually under 18.5) than you are underweight. Contrary to popular belief, underweight is a risk factor for many diseases and extreme weight loss can lead to death. So be careful!

Normal or ideal BMI is from 20 to 24.99, women might consider ideal the lower half, whereas men the upper. If your BMI falls into this category you are fit!

BMI values greater than 25 are considered overweight. If it is under 30 then it wouldn’t be bad to loose some weight, but you are not at risk. The problems arise especially for BMI over 30. This is a condition called obesity (it has 3 degrees) and is associated with metabolic, cardiovascular, skeletal diseases and so on. If this is your case it is wise to have a diet and maybe try some natural weight loss pills along starting to exercise.

Don’t forget to achieve a steady pace of losing weight, for your body had 5, maybe 10 years in which gained your actual weight and it is completely unnatural and unhealthy to loose this weight overnight!
