TT is a 15-year-old overweight student in to see the school nurse about weight loss. Together they examine her diet history and daily physical activity.
 
  The nurse explains that currently her intake is greater than the demand for energy, resulting in a positive energy balance. In order to lose weight a negative energy balance will have to be reached by: 1. Drinking only liquid dietary supplements for one month to change her metabolic rate.
   2. Decreasing kcalorie intake and increasing physical activity to promote a slow weight loss.
   3. Reducing food portions to one-half of normal and exercising daily.
   4. Eating only fruits and vegetables.

Question 2

An important role of proteins in the body includes
 
  a. temperature regulation.
  b. acid-base balance.
  c. conduction of nerve impulses.
  d. elimination of waste products.

Answer to Question 1

2
Rationale: Creating negative energy expenditure by decreasing the number of kcalories consumed daily and increasing physical activity has been shown to be the most effective way to achieve long-term success with weight loss. Radial decreases in food intake produces a negative energy expenditure, but at the cost of adequate nutrition. Reducing food portions by one-half may be an extreme cut unless previous portions are massive. The best diet is one balanced to provide all the nutritional requirements of the body.

Answer to Question 2

B
An important role of proteins in the body includes acid-base balance. Proteins do not have a ma-jor role in temperature regulation, conduction of nerve impulses, or elimination of waste products.
