Body Mass Index Defined

Health-conscious individuals need to understand weight-related terms. No other word is as closely associated to weight as the word metabolism. People often refer to themselves as having a slow or fast metabolism.
What exactly is Metabolism?   Metabolism refers to all the chemical processes that are taking place within the body by which the food you eat is converted into the energy your body needs to function.
And there are a lot of influencing factors that can influence the metabolic rhythm such as gender, genetic facts, environmental temperature, stress, and also the quality and quantity of exercise. The measurement that evaluates the relationship between body weight and height and is the recommended method by medical professionals to diagnose overweight and obesity is the Body Mass Index (BMI).
There is no such thing as an ideal body weight but there is what you call a healthy weight range.  The Body Mass Index is the height-weight system that will determine this healthy weight range.

The BMI formula (in pounds/inches) is:
Your Weight (in pounds) x 704.5 divided by Your Height (in inches) x Your Height (in inches)

A handy tool used to calculate BMI index is the Body Mass Index Calculator. This is one of the most accurate ways to determine if extra pounds pose health risks. In general, when people use the word metabolism they used this interchangeably with Basal Metabolic Rate (BMR).

How Body Mass Index Classifies Weight

Under 20 (19 for women) = Underweight
Between 20 and 24.99 = Normal Weight
Between 25 and 29.99 = Overweight
Between 30 and 34.99 = Obese Class 1
Between 35 and 39.99 = Obese Class 2
40 and above = Morbid Obesity

This is the sum-total of all the energy consuming process going on in the body while it is resting and the release of this energy is only sufficient for the vital functioning of the heart, lungs, nervous system and kidneys. If the Basal Metabolic Rate is the number of calories your body needs when you are resting and multiplied by your activity level, BMR then lets you estimate how many calories you need to lose weight or maintain your current weight.

If you calculations fall outside of the normal range and you are not an athlete, then consult with a licensed medical practitioner to achieve your goals.
