Question 1

Most popular weight-loss diet plans, such as Atkins, Jenny Craig, South Beach, Weight Watchers, and the Zone, may successfully induce weight loss in the initial stages of the program because all such diets

Accepted Answer

Most popular weight-loss diet plans induce initial weight loss primarily because they are low in calories. Reducing calorie intake is a fundamental principle for weight loss, regardless of the specific macronutrient composition of the diet.

Question 2

Weight loss should be monitored with skinfolds and girth measurements, as well as with a scale, to ensure that
it is body fat that is being lost.

Accepted Answer

Using skinfolds and girth measurements in addition to a scale can provide a more accurate picture of body composition changes, ensuring that weight loss is due to fat loss rather than muscle loss.

Question 3

The palm of your hand may be a convenient guide to measuring portion sizes of food. Which of the following would be a good approximation?

Accepted Answer

The palm of your hand (excluding fingers) is approximately the size of a 3-4 ounce portion of meat, chicken, or fish, making it a useful visual guide for estimating appropriate serving sizes.

Question 4

If one follows a dietary regimen that stresses balanced nutrition with a reduced caloric intake and a behavior
modification program to insure the diet's implementation, a comprehensive weight-control program has been achieved.

Accepted Answer

The answer of If one follows a dietary regimen that...

Question 5

According to the latest government report, the majority of American adults are overweight.

Accepted Answer

Recent data from the Centers for Disease Control and Prevention (CDC) indicate that a significant portion of the adult population in the United States is classified as overweight or obese, based on Body Mass Index (BMI) criteria.

Question 6

Setting short-term goals that may be attained in a reasonable length of time is a very important step in your
weight control program.

Accepted Answer

Setting short-term, achievable goals is a key strategy in weight management programs because it helps maintain motivation and provides a sense of accomplishment, which can encourage adherence to the program.

Question 7

Athletes, such as wrestlers, who desire to loss excess body fat but help maintain lean muscle mass, may be advised to increase the proportion of their daily caloric intake from which nutrient?

Accepted Answer

Protein is essential for maintaining and building lean muscle mass while losing fat. It helps in muscle recovery and growth, and diets higher in protein have been shown to support fat loss efforts, making it the best choice for athletes looking to maintain muscle while losing fat.

Question 8

During the first few days of your diet, about 70 percent of the weight loss is due to body-water changes.

Accepted Answer

During the initial phase of a diet, especially one that reduces carbohydrate intake, the body sheds a significant amount of water weight. This is because carbohydrates are stored in the muscles and liver as glycogen, which binds water. When glycogen stores are used for energy, the water previously bound to them is released and excreted, leading to a rapid decrease in body weight that is primarily water.

Question 9

It is always necessary to take a daily vitamin/mineral supplement when one is dieting.

Accepted Answer

While some diets may limit intake of certain nutrients, making a supplement necessary, not all diets or individuals require supplements. It's best to tailor supplement use to individual dietary needs and deficiencies, which can often be met through a balanced diet.

Question 10

The caloric needs of boys and girls are dissimilar in terms of Calories needed per kilogram of body weight
throughout their life span.

Accepted Answer

The answer of The caloric needs of boys and girls...

Question 11

At the end of three weeks of dieting, weight loss will slow as a natural consequence of the diet, but the weight
being lost at this point will be primarily body protein.

Accepted Answer

Initially, rapid weight loss is often due to water loss and glycogen depletion. Over time, weight loss can slow down as the body adjusts to a lower calorie intake and changes in metabolism, but it doesn't necessarily mean that the weight being lost is primarily body protein. Fat loss continues to be a significant component of weight loss over time, especially with a balanced diet and exercise.

Question 12

Although the Food Exchange System is not a rigid diet plan, it has the following minimum requirements: 2
starch/bread exchanges, 5 skim milk exchanges, 4 lean meat exchanges, 2 vegetable exchanges, and 2 fruit exchanges.

Accepted Answer

The Food Exchange System does not have a set minimum requirement for each food category as it is designed to be flexible and adaptable to individual dietary needs and preferences. The system categorizes foods into groups with similar macronutrient profiles to help in planning balanced meals, but it does not mandate specific minimums for each category.

Question 13

Fat and sugar together account for nearly 50 percent of the Calories in the average American's diet.

Accepted Answer

The average American diet is high in both fat and sugar, which together contribute to a significant portion of total caloric intake, often nearing or exceeding 50 percent. This is due to the prevalence of processed foods, fast foods, and sugary beverages in the diet.

Question 14

A Body Mass Index above 20 is considered obese.

Accepted Answer

A Body Mass Index (BMI) above 30 is considered obese according to the World Health Organization's classification.

Question 15

According to numerous well-controlled research studies, which of the following dietary supplements has been shown to be a safe and effective means to induce significant loss of body fat?

Accepted Answer

Most well-controlled research studies have not found carnitine, chromium, ginseng, or synephrine to be safe and effective means to induce significant loss of body fat. The effectiveness of these supplements for fat loss lacks substantial scientific support, leading to the conclusion that none of the options listed are proven to be effective for this purpose.

Question 16

The maximal recommended weight loss per week without medical supervision for growing children is 2 pounds
per week.

Accepted Answer

For growing children, weight loss should be approached with caution and typically not exceed 1 pound per week to ensure they receive the necessary nutrients for growth and development.

Question 17

One key principle in selecting foods for weight control is to choose quality Calories and include more natural,
unrefined products in one's diet.

Accepted Answer

Choosing quality calories and incorporating more natural, unrefined products into the diet can help manage hunger, improve nutrient intake, and support weight control by providing the body with more fiber, vitamins, and minerals while avoiding excessive added sugars and unhealthy fats.

Question 18

One characteristic of dieters who have lost weight and managed to keep it off is that they weigh themselves on
a regular basis, often daily.

Accepted Answer

Regular self-monitoring, including frequent weighing, is a common strategy among individuals who have successfully lost weight and maintained their weight loss over time. This practice helps in keeping track of progress and allows for early detection and correction of small weight gains.

Question 19

Much information is available concerning the Food Exchange System. However, knowledge is not the total
answer; one's behavior must reflect the knowledge for the system to be successful.

Accepted Answer

Understanding the Food Exchange System is important, but applying this knowledge through behavior change is essential for the system to be successful in managing diet and health.

Question 20

Which of the following macronutrient diets, each with the same caloric content, has been shown to be the best for weight loss?

Accepted Answer

Studies have shown that when caloric intake is equal, there is no significant difference in weight loss among different macronutrient compositions. The key factor for weight loss is the caloric deficit, not the specific macronutrient ratio.
