What is Body Mass Index - BMI
Body Mass Index is a good gauge of Body Fat.

Body mass index (BMI) is measure of body fat based on your height and weight that applies to adult men and women. BMI is a good
gauge of your risk for diseases that can occur with more body fat. It provides an estimate of total body fat and your risk of developing
weight-related diseases.

Your Body Mass Index is important when assessing how much fat you have and how much fat you need to lose. If your BMI is over
the healthy range (18.5-24.9), it means that you are probably carrying extra fat and your health could be at greater risk.
The higher your BMI, the higher your risk for certain diseases such as heart disease, high blood pressure, type 2 diabetes,
gallstones, breathing problems and certain cancers.

High BMI means you are overweight or Obese and medical researchers warn that these are not just cosmetic but also serious health

Healthcare professionals around the world often use Body Mass Index (BMI) when determining whether you are underweight,
healthy weight, overweight or clinically obese.

BMI tool is recommended by worldwide governmental organizations, health researchers and doctors and medical organizations as
standard tool for determining body fat :-
WHO (World Health Organization)
US Dept of health and human services
Centers for Disease control and Prevention - USA
Dept of Health -UK
Victorian Department of Health & Human Services - Australia
Although BMI can be used for most men and women, it does have some limits :-

BMI is not a perfect measure, because it does not directly assess body fat. Muscle and bone are denser than fat, so an athlete or muscular person may have a high BMI, yet not have too much fat. But most people are not athletes, and for most people, BMI is a very good gauge of their level of body fat.

Example 1-
- It may overestimate body fat in athletes and others who have a muscular build.
- It may underestimate body fat in older persons and others who have lost muscle.

Example 2 -
A 6 feet 2 inch athlete may have a higher BMI than a couch potato of the same height - but the couch potato may be overweight while the athlete is definitely not.
Research has shown that BMI is strongly correlated with the gold-standard methods for measuring body fat. And it is an easy way to screen who might be at greater risk of health problems due to their weight.
CBS News -
In 2012, 5.3 million deaths tied to physical inactivity. Smoking, meanwhile, is responsible for about 5 million deaths worldwide.
How to calculate BMI - Adult Men and Women
Where do you stand ?
Metric option -
Divide your weight in kilograms by height in meters squared.
BMI (kg/m2) = weight in kilograms / height in meters x meters

For example:
- Weight 90 kilograms
- Height 1.9 meters =
- Squaring of Height = (1.9)2 = 3.8
- 90 divided by 3.8 =  23.68
So your BMI is 23.68

BMI between 30 and 40 is Obese.
BMI over 40 is classed as very Obese, Morbidly obese
Healthy Move - A small weight loss can have a big impact on your health. If you reduce only 5 to 10 percent of your current weight then you may gain measurable benefits that include improvements in blood pressure, blood cholesterol and blood sugars. In addition to improved physical health, physical mobility, general mood and self-confidence will also get improved -
Underweight     Ideal Weight     Overweight      Obese         Morbidly Obese
Causes of High BMI (overweight or Obesity)
Though there are various reasons for High BMI (Body mass Index) but primarily there are two reasons and research shows that most of us fall in these two categories.
1. Calorie Imbalance and
2. Sedentary life (no or irregular physical activity)
Sedentary Life

Sedentary life is one of the major causes for weight gain and leading to high BMI (body mass index). A sedentary life is a type of lifestyle with no or irregular physical activity.  Sedentary activities include computer use for much of the day, sitting for longer duration for professional or personal activity, spending more time  in activities like reading, writing, watching television, etc.

In sedentary life style the major problem is food imbalance means whatever we eat doesnít get digested (because of no physical activity) and hence accumulation of calories and over a period of time these calories will convert into fat resulting in weight gain. Important factor to notice in sedentary life style is food imbalance.

Healthy Move - It takes approximately 3,500 calories below your calorie needs to lose a pound of body fat - to lose 1 to 2 pounds a week, the caloric intake must be reduced by 500-1000 calories per day.
Some other reasons for high BMI (getting Overweight or Obese)
Overeating (consuming more calories)
In active life style
Insufficient or poor quality sleep
No physical exercise
Poor Nutrition
Eating disorders
Smoking cessation and other stimulant withdrawal
A diet high in sugars like soft drinks, soda
Genetic predisposition
Hormonal imbalances due to medication

According to WHO (World Health Organization) and US Dept of health and human services, BMI values are age-independent for adults (above 20 years) and same for both sexes.
As per WHO (World Health Organization) guidelines, BMI provides the most useful population-level measure of overweight and obesity as it is the same for both sexes and for all ages of adults.

However, it should be considered a rough guide because it may not correspond to the same degree of fatness in different individuals.

BMI Formula -
Calculation of Body mass index (BMI) is very straightforward. Calculating body mass index requires only two measurements - height & weight.

The formula is as follows:
There are two ways - Metric and Imperial
Imperial Option -
Your weight in pounds, multiplied by 703, divided by the square of their height in inches.
BMI = (weight in pounds x 703) / height in inches x inches

For example:
- Weight 190 lbs
- Height 72 inches (6 feet)
- Squaring of Height = (72)2 = 5,184
- 190 multiplied by 703 divided by 5,184 = 25.76
- So your BMI is 25.76
There are two calculation options -

- Metric option (Enter weight in kilograms and height in meters) and
- Imperial Option (Enter weight in pounds and height in inches )
Please Note:
BMI calculator is not meant to serve as a source of clinical guidance and is not intended to be a substitute for professional medical advice. Since BMI is based on weight and height, it is only an indicator of body fatness. Individuals with the same BMI may have different amounts of body fat. Persons may consider seeking advice from their health-care providers on healthy weight status and to consider individual circumstances.
Calorie Imbalance -
A calorie is defined as a unit of energy supplied by food and is a calorie regardless of its source - carbohydrates, fats, sugars, or proteins, all of them contain calories.
The number of calories you need to eat each day depends on several factors, including your age, size, height, gender and lifestyle.
For example - A physically active 6ft 2in male, aged 22 years, requires considerably more calories than a 5ft 2ins sedentary woman in her 70s.

Calorie imbalance is nothing but more calories are consumed through food and drink and lesser calories are spent or utilized.
Generally most of us consume more calories than we spend and this is the primary reason for calorie imbalance and hence weight gain and resulting in high body mass index (BMI)

Calories that don’t get utilized by us will start accumulating and over a period of time they get stored as fat resulting in overweight or obese or High BMI.
A growing issue related to high BMI (overweight or obesity) is an individual’s food habit.
Areas that need to be looked into more thoroughly are fats consumption, food quantity and sugars.

According to one study approximately 67% of sugar-sweetened beverages consumed are soda. Soda consumption has been demonstrated to be one of the leading causes of the rapid growth of obesity in the US.

Sugar-sweetened beverages (SSB) do not seem to provide adequate fullness. Fullness leads a person to stop eating after having sufficient food. Lack of fullness prevents individuals from compensating for the calories ingested from SSBs during later meals, this dynamic leads to a higher total caloric intake overall.
Signs of fat storage in women - breasts, waist, hips, and buttocks. This is reason why women start looking bulky and shapeless.
Signs of fat storage in men - chest, abdomen, and buttocks. Most of the men develop a belly.

Caloric balance and body weight are generally maintained by balancing calories consumed against calories used by normal bodily functions and exercise. Thus, by consuming as many calories as expended and vice-versa, a person’s weight will remain stable. High BMI results if the food intake exceeds and no or irregular physical activity is carried out.
As per WHO (World Health Organisation) - Globally, there has been:
An increased intake of energy-dense foods that are high in fat; and
An increase in physical inactivity due to the increasingly sedentary nature of many forms of work, changing modes of transportation, and increasing urbanization.
Physical activity is the most variable component of energy expenditure, and the main component a person has control over.
-US National Library of Medicine National Institutes of Health
No Exercise

Another major contributing factor of high BMI (overweight or obesity) is lack of exercise. One of the research organization said being overweight and obese results from an energy imbalance caused by eating too many calories and not getting enough exercise.

There are certain set people who consume heavy calories but do enough exercise due to this there is no question of calorie accumulation and no weight gain.
WHO (World Health Organization) -
Physical inactivity is the fourth leading risk factor for global death, after high blood pressure, smoking and high blood glucose, and levels of physical inactivity are rising in many countries.
- In 2008 around 3.2 million deaths per year are due to physical inactivity.
- Over 670 000 premature deaths (people aged under 60 years).
- Physical inactivity is estimated as being a cause of breast and colon cancer, 27% of diabetes and 30% of ischaemic heart disease.
An excess energy intake, even a small amount over a long period and lack of exercise will cause weight gain leading to Overweight and then Obesity.
