Is my weight healthy?

It sounds like a simple question, but it may surprise you to learn that the answer is more than a number on a scale. An accurate answer can make a life-changing impact on the way you look, live and feel.

Your BMI, or Body Mass Index, is a wellness indicator that uses a scientific formula to determine your most healthy weight based on your age and height.

Please enter numbers only.



Your body mass index (BMI) is:

What your results mean

Your BMI provides a helpful guideline for achieving the weight range that's healthiest for you. You can interpret your BMI results as follows:


Below 20 Slender-Lean
20 to 25 Ideal Weight Range
25 to 30 Overweight (25-27 could be healthy range if large-boned and heavily muscled)
30 + Very Overweight / High Risk
40 + Significantly Overweight / High Risk for health complications

Why know your BMI?

As you set personal goals on the way to changing how you look and feel, your BMI can serve as an accurate indicator of overall well-being. A high BMI can be associated with serious health risks including :

Heart disease

Self Care strategies for reducing your BMI

Obesity is the excessive accumulation of adipose tissue to an extent that health is impaired.(1)

Check your BMI

Body Mass Index (BMI) is the standard measurement of choice for many health professionals.

BMI is based on a weight-to-height ratio.

Overweight is defined as a BMI>=25 and <30 kg/m².

Obesity is defined as a BMI >=30 kg/m². Obesity correlates strongly with obesity related co-morbid conditions and mortality.

To check your BMI see the chart on this page

Waist Circumference

Waist circumference is another widely used measurement to determine abdominal fat content. An excess of abdominal fat, when out of proportion to total body fat, is considered a predictor of risk factors related to obesity.

Men with a waist measurement exceeding 40 inches are considered at risk. Women are at risk with a waist measurement of 35 inches or greater.

Several Health Risks and Conditions Associated with Obesity Include:

Heart Disease
Some types of Cancer
Sleep Apnea
Gallbladder Disease

Obesity - an Epidemic
Overweight and obesity has reached epidemic proportions in the United States, as well as worldwide.(3)

Data collected by the National Center for Health Statistics indicate that the prevalence of obesity, defined as a body mass index >30 kg/m² has increased from 12.8% in 1976-1980 to 22.5% in 1988-1994 and 30% in 1999-2000. 4)

Roughly 31% of American adults meet the criterion for obesity - about 59 million American adults. More than 64% of the US adult population have a BMI >=25 kg/m².(4)

In an effort to increase public awareness of the epidemic proportion of obesity, the Surgeon General has issued a call to action to prevent and treat overweight and obesity and their associated health complications.(5)

Decreasing Dietary Fat Is Associated with a Decrease in Body Weight

Let's talk about some of the dietary changes that can be considered to help reduce energy intake. There is a lot of clutter in the press and popular publications.

Diet books usually occupy a couple of places in the top ten lists of nonfiction books, although in some cases I think they should probably be on the fiction list, depending on the particular diet.

A lot of people are confused about what they are supposed to be eating to lose weight.

I want to emphasize that calories are very important. You may need to emphasize that to your patients because I think many people have lost sight of that.

One number that you might want to remember for working with your patients is that 3,500 calories energy is contained in every pound of body fat, and so in order to lose a pound of body fat, not water, it's necessary to burn 3,500 calories more than you take in.

By the same token, the person who takes in 3,500 calories more than they burn would expect on average to gain a pound of body fat. Even a hundred calories a day difference between intake and expenditure, if continued in the same direction, over the course of a year can amount to a ten pound body fat difference.

This can certainly explain how it is that we can gain weight continuously over time, even when taking in a hundred extra calories a day.

On the other hand, for the patient who is a little discouraged, pointing out some ways that they can reduce their energy intake by a hundred calories a day, and perhaps increase their expenditure by a hundred calories a day can make it seem much more manageable.

Apart from the calories, people want to know what the constituents of their diets should be. This slide is a summary of 37 studies that were conducted using cholesterol-lowering diet step 1 and step 2.

They have been graphed according to the average reduction in body fat and dietary fat, compared to the change in body weight.

You can see that in general, the interventions that resulted in the greatest reduction in dietary fat also had the greatest effect on weight loss. So it obviously shows the wisdom of trying to lower dietary fat from the diet.

Diet change strategies:

Even when we try to eat well, we're disadvantaged. The nutritional content of most food has been compromised over the years, not only by deficient soils and modern production, transportation, storage and processing methods, but also by the enormous amounts of chemical and artificial substances added to promote growth, storage life, taste and appearance.

It's for this reason that more and more medical authorities are advocating the use of vitamin and mineral supplements. However, finding them in the right combination can be both confusing and costly.

The nutrition products I am going to recommend you make use of knowledge gained from the botanical world's 6,000 year history. They incorporated health building nutritional herbs with the best modern technology to help our bodies cleanse and detoxify so that the cells - the tiniest living units - can be as fully nourished as possible.

This allows the cells to grow, repair and to perform their functions with the best possible efficiency so that we feel and look better and are more able to prevent and fight disease. Once the body begins to clear itself of toxins it can more efficiently absorb nutrition.


This problem, like so many others, indicates that your body system is working to deal with underlying problems.

This may be a build up of toxins and poisons in your system and the symptoms you are experiencing is part of your bodies attempts to deal with them.

You may find benefit from our information on Detoxifying through change of diet.

It may be due to difficulties with your digestive system that is causing your body to be starved of key nutrients, vitamins or minerals.

In this case you may find useful answers by reviewing our article on Nutrition For Your Cells.

It may be that your metabolism has slowed due to pressures that have been placed on your system through life in general or through specific “challenges” you have faced in the last few months or last few years.

Review this by looking at our article about balancing your Metabolic Rate.

Further reading through our articles on health issues will give you a body of information that will help you decide what options you have to deal with the underlying causes of your problem through giving your body the nutrition products that will assist you body to heal from the inside out.

We wish you well in your search for solutions to this problem and your movement towards better health in all areas.
