How to tell if you have a Healthy Weight

After working with WiiFit for quite a while now, yesterday I decided to research a bit about BMI(Body Mass Index) good and bad weight etc and found interesting stuff which I thought of sharing with you all. If you don’t already know it, it’s a good read.

Okay so a good thing to know is that being Overweight and being Obese are two different things.
However both terms mean that the body weight is more than what it should be for a given height.

A body weight may include muscles, bones, water or fat.
Overweight is having more weight than one should according to his/her height regar
dless of what the weight comprises of.

A person is obese if the all the extra weight is because of fat content. .

It is important to know whether your weight falls within healthy weight range or not because there are certain health risks that maybe associated with extra body weight like heart attack, diabetes, high blood pressure, osteoarthritis etc.

A good way to measure your body fat is to calculate your BMI.
The formula is -
BMI = (Weight in Kilograms / (Height in Meters) x (Height in Meters))
This is to evaluate a BMI of adult but not for children and is based on height and weight.
These BMIs are defined by
National Institutes of Health(NIH) as

Underweight-BMI (less than 18.5)
Healthy weight – BMI (18.5-24.9)
Overweight – BMI (25-29.9)
Obese- BMI (30 or higher)

Though BMI is a good estimate of excess weight, it has certain limitations because it does not give you an idea about the difference between muscle and fat, also it does not consider age and gender and therefore it is possible for a fit person to have a BMI in unhealthy range just because s(he) has more muscle mass like athletes.

Waist circumference is believed to be another good estimate of your body fat.

A person having body fat around waist has more chances of developing health related problems like high blood pressure etc than a person having body fat somewhere else.

According to
NIH
Women with waist measure of 35 inches or more maybe at increased health risks.

Men with waist measure of 40 inches or more maybe at increased health risks.

So I guess it’s a good idea to keep our waist circumference as well as body weight within the healthy range.
