Overweight

The minimum average energy requirement for a sedentary adult to survive is around 2,000 kcal a day, which rises to 4,000 or more if the person is engaged in strenuous labor much of the day. Only a very small percentage of the U.S. population is involved in strenuous labor, yet much of the population consumes over 4,000 calorics each day, resulting in an America that is 50 percent overweight and 20 percent obese. 

Since Americans enjoy the cheap food supply made possible from a huge agricultural surplus, and there seems to be no desire to reject technology and go back to a reliance on manual labor, the food surplus problem of an overweight and obese America is likely to remain for years to come. 

We hear a lot these days about the relationships between saturated fats, cholesterol, and heart disease. What are the facts It s well established that a diet rich in saturated animal fats often leads to an increase in blood serum cholesterol, particularly in sedentary, overweight people. Conversely, a diet-lower in saturated fats and higher in polyunsaturated fats leads to a lower serum cholesterol level. Studies have shown that a serum cholesterol level greater than 240 mg/dL (a desirable value is <200 mg/dL) is correlated with an increased incidence of coronary artery disease, in which cholesterol deposits build up on the inner walls of coronary arteries, blocking the flow of blood to the heart muscles. 

The average basal metabolic rate for humans is about 65 keal/h, or 1600 keal/day. Obviously, the rate varies for different people depending ori sex, age, weight, and physical condition. As a rule, the BMR is Jow er for older people than for younger people, is lower for females than for males, and is lower for people in good physical condition than for those who are out of shape and overweight. A BMR substantially above the expected value indicates an unusually rapid metabolism, perhaps caused by a fever or some biochemical abnormality. 

Obesity is defined by the body mass index (BMI), measured as body weight in kilograms divided by the squared height in metres (kg/m2). A BMI of 30 or more is a commonly-used criterion for defining obesity and a BMI between 25 and 30 is considered overweight. 

For overweight adolescents and adults, autoinjectors containing a 0.5-mg dose of epinephrine are needed however, this dose is not available in most countries. Moreover, in many overweight people, attempts to inject epinephrine intramuscularly from most currently available autoinjectors are likely doomed to failure, because the attached needle is too short to penetrate the poorly vascularized adipose tissue layer over the vastus lateralis [26]. 

The study site, consisting of about 11 contaminated acres belonging to eight property owners, is in a small community midway between Verona and St. Louis, Missouri. Records indicate that on May 20, 1971, a truck driven by an employee of a salvage waste oil company was ticketed for being 950 pounds overweight. The truck was en route from Verona to St. Louis with a load of TCDD-contaminated still... 

Obesity has reached epidemic proportions in most industrialized countries over the last two decades. Many serious diseases, such as stroke, diabetes mellitus and other chronic conditions, are directly related to being overweight (1, 2). The number of adults who are classified as extremely obese tallies in the nullions for the United States alone (3). The number of children that are most likely obese adults for the rest of their lives has tripled in the same time period (3).
