An Explanation of the BMI Calculator

In the mid 1800’s Belgian scientist Adolphe Quetelet developed the Quetelet index, which is known today as the body mass index (BMI). This statistical measurement compares a person’s height and weight and is a useful tool to identify weight problems within a population or for an individual. Though a BMI Calculator cannot measure the actual percentage of body fat, its ease of calculation makes it a popular diagnostic tool for health experts.

The body mass index is defined as an individual’s body weight (in kilograms) divided by the height (in meters) squared.

For imperial units, the formula is modified as follows:

Height in Inches: [weight (lb)* 703] / [height (in) * height (in)] Height in Feet: [weight (lb) * 4.88] / [height (ft) * height (ft)]

Body mass index was always intended to be a general guide for health professionals. However, doctors must consider other factors on a case-by-case basis. For example, muscle density, bone density, and ethnic origin can skew the results of a BMI Calculator. For a general guideline, the body mass index is broken into separate categories outlined below with the corresponding BMI: Severely Underweight – Less than 16.5 Underweight – 16.5 to 18.5 Normal – 18.5 to 25 Overweight – 25 to 30 Obese Class I – 30 to 35 Obese Class II – 35 to 40 Obese Class III – Over 40

Using the BMI Calculator, a health and nutrition survey in 1994 found that 59% of American men and 49% of women have a body mass index over 25.  In America individuals with a BMI higher than 40 are considered morbidly obese, which accounts for 2% of men and 4% of women. A more recent survey in 2007 shows an increase in America’s weight, with 63% of Americans considered overweight and 26% in the obese category. For individuals who are underweight, a BMI close to 15 is an indicator of starvation, and 17.5 is an informal indicator of eating disorders such as anorexia nervosa.

It is very common to consider the BMI Calculator in the medical underwriting of private health insurance plans. Providers will use a high BMI as a cut-off point to raise insurance rates or deny coverage. Furthermore, the BMI is often used by surgeons to determine if a patient qualifies the Gastric Band procedure. Typically, doctors are looking for a BMI of 35 or higher when considering potential candidates. Each case should be considered on an individual basis, but the BMI calculator does serve as a useful tool.

Three Safe and Fast Weight Loss Diet Approaches

Two Basic Approaches

One safe and fast weight loss diet approach involves looking at ways to decrease the total number of calories consumed in a day. The core of the second approach is to consume relatively the same but get busy by exercising. Both of these approaches will produce fat loss over a period of time. Whatever particular Fast Weight Loss Diet you choose will be dependant on your lifestyle or amount of discipline you have. So lets take a closer look at these fast Weight Loss diet Strategies.

Some great Fast Weight Loss diet programs can be found here: healthy diet progams for fast weight loss.

Assess Your Eating Habits

The fast weight loss diet strategy that has you eating less food is an effective strategy. If you simply reduce the number of high calorie carbohydrates you can decrease calories significantly. Reducing the amount of bread with meals is a good example of cutting out calories from carbs. Eliminating some condiments from meals can decrease calories easily as well. You will have to reduce calories by 3200 for each pound you want to lose. If you look carefully at your meal content you can find ways to simply and easily reduce the amount of daily calories.

Burn More Calories

A second fast weight loss diet approach involves increasing fat loss from increased activity levels. If you are not getting a lot of exercise each day small increases can lead to additional fat loss. It doesn’t mean you have to train like a marathon runner only small increases in your exercise level will do. A program that includes three days a week of intense exercise can contribute to 5-8 lbs of fat loss per month. Most find this target goal sustainable and achievable. No matter which one you choose it will burn fat more and lead to significant weight loss.

Two-Prong Approach

The fast weight loss diet plan that uses both approaches is twice as effective as a single approach alone. Because it involves both approaches, weight loss will occur on two fronts at the same time. In fact some have even increased their food consumption by 3% and found they still have significant weight loss. The key to this approach is not to do too much too quickly and give the body time to adapt to the change. The reduction of calories and the increase of exercise should be approached in increments not to exceed five per cent per week. Instead of consuming three large meals they change their [eating] schedule to include 6 small meals. Just be sure to be aware of the total amount of calories you are eating.

Be Reasonable

A fast weight loss diet should not only be effective but it should be safe also. Losing weight or exercising progressively is the best approach for long term results. Some may think so but it is just not the right way to approach fat loss. A reasonable amount of fat loss per month is between 5-8 pounds. When considering your weight loss, plan for the long-term. This will ensure your body gets adequate nutrition and not engage the starvation mode. If this happens then weight loss will be stopped temporarily. Slow and steady will win the race in a reasonable and safe manner.
