Nutritional Diseases and Obesity
Obesity – A Nutritional Disease
The nutritional disease of obesity is a chronic condition defined by an excess amount of body fat. A certain amount of body fat is necessary for storing energy, heat insulation, shock absorption, and other functions. The normal amount of body fat (expressed as percentage of body fat) is between 25-30% in women and 18-23% in men. Women with over 30% body fat and men with over 25% body fat are considered obese.
The amount of body fat has been measured by body mass index or BMI. BMI can be determined by dividing your weight in pounds by your height in inches, and dividing that number again by your height in inches, and multiplying that number by 703.
A normal BMI is 18.5 to 24.9. Overweight is a BMI 25.0 to 29.9, and obese is 30 BMI or greater. Morbidly obese is 40 BMI or greater.

Obesity. A lifestyle choice that may become the number one preventable cause of death.
Smoking is the #1 preventable cause of early death worldwide. Obesity is the 2nd leading preventable cause of death and may soon be #1.
BMI has been the standard of determining obesity. A world wide study reported in 2005 at URL http://www.medpagetoday.com/PrimaryCare/Obesity/2069 states that waist to hip measurements were much more important than BMI in determining heart attack risk.
Obesity, an accumulation of abdominal fat, is linked to heart disease, insulin resistance, diabetes, and cancer in both men and women. Excessive dietary calories and lack of exercise are the causes of obesity. Exercise is King and Diet is Queen in controlling obesity. Both are better than either one.
Understand the risks, make use of the benefits of diet and exercise, and begin a life of freedom from the modern nutritional diseases.
Excess body fat is a problem in all developed countries. It has nearly doubled from 1991 to 1998. It is the 2nd leading cause of preventable death and may soon be #1. Smoking is the leading cause of preventable death.
It is not just a problem of being overweight. A person may be overweight but have a large muscle and bone mass, and a very low percentage of fat. A person in a normal weight range with a very sedentary life style may have very little muscle and bone mass but have a very high percentage of fat and therefore be obese.
About one-half of Americans are above their ideal weight, and as many as 1/3 are obese. Two principal risk factors that lead to obesity are poor nutrition, including eating too many calories. The other half of the equation is a sedentary life style, or lack of physical exercise.
In the United States, roughly 300,000 deaths per year are directly related to excess body fat. Abdominal obesity,surrounding the internal organs, accounts for about 90% of the risk for heart attacks around the world. Eight other risk factors, including cigarette smoking, diabetes, poor diet, and lack of exercise account for the rest.
There are a number of diets that have been proposed to be a cure for obesity, such as the Atkins, or South Beach diets. However none have been successful in long term weight or fat loss in controlled clinical studies. The only thing that really works is for individuals to eat less calories than they expend.
A lack of physical activity and addiction to sugar and other highly refined carbohydrates, which have large calorie loads but no nutrients, will pack on the pounds in a hurry. Add to this the mindless consumption of chips, cookies, etc., prevalent in our society, and blood sugar levels rise sharply. High carbohydrate intake can lead to a roller coaster effect which leads to high insulin levels, and obesity.
There is evidence of genetic, metabolic and environmental factors or influences that contribute to obesity. Cushings syndrome, or hypothyroidism, and medications such as glucocorticoids can also cause excess weight gain. However less than 1% of obese individuals have a secondary cause of obesity.
Obesity is not just a cosmetic consideration; it is a dire nutritional disease directly harmful to one's health.

What Others Have Suggested
Insulin Resistance What is the cause?
Fragile omega 3 oils have the cis configuration. They smoke during frying and result in trans fats which are absorbed by the fried material. These trans fats are used in place of the omega 3 oils in the cell membranes after ingestion. This makes for an unnatural site for insulin to attach to the cell membrane. It takes a larger amount of insulin to bring about the uptake of glucose into the cell. This results in hyperinsulinemia,(above normal amounts of insulin) and is identified with many, if not most, of the chronic disease symptoms related to elevated insulin and blood glucose levels.
According to The Fat Loss Bible correct weight loss is a science, but it does involve discipline.
We need to understand the dangers of insulin resistance.
Obesity and insulin resistance are modern nutritional diseases
