The minimal percentage of body weight that may consist of body fat is 3% in men and 8% in women; so, 120 lb (0.08) = 9.6 lbs. Some body fat is essential to survival. Every cell membrane in the body has fat molecules in it, and fat is used for insulation and many other functions.

12

Mary is a 32-year-old woman who admits to repeated episodes of eating large quantities of food at one sitting, including two boxes of cookies, a family-size bag of chips, six candy bars, and even more at times, then vomits to rid her body of the food. This would be an example of

a. 1000
b. 3000

d. 7000


7000

a. helpful but expensive.
b. the only alternative for extreme obesity.
c. associated with significant risks.
d. not effective.

associated with significant risks.

Significant risks are associated with surgical techniques for weight reduction along with other problems and side effects. Inherent risk of surgery and postsurgery malnutrition are critical issues that should be thoroughly addressed with the patient.

17

In all probability, the most significant factor in the development of obesity is
a. genetics and family food patterns.
b. psychological influences.
c. social influences.
d. physiologic influences.

genetics and family food patterns.

18

a. no different from that of any other child.
b. very great.
c. very low.
d. dependent on other environmental factors.

very great.

Up to 80% of the predisposition to obesity is from genetic factors. However, a genetic influence is not the determining factor. The daily life, environment, and habits the person chooses influence the expression of this gene trait.

19

25

A hormone that seems to control eating behavior and fat storage is

26

Dangers associated with the use of very-low-calorie diets include

27

Body wraps result in a loss of

water.

Body wraps result in the loss of body water. Special “sauna suits” or body wrapping claims to help weight loss in certain spots of the body or clear up so-called cellulite tissue (the term cellulite is not a scientific term). The resulting small weight loss is caused by temporary water loss.
