Question 1

Maintaining an energy-restricted diet that is high in nutrients requires significant planning and preparation of most of your own meals.

Accepted Answer

Maintaining an energy-restricted diet that is high in nutrients often requires careful planning and preparation of homemade meals, as it can be difficult to find pre-made meals that meet specific nutritional criteria.

Question 2

Antioxidant supplements have consistently been shown to lower rates of death from heart disease and certain types of cancer.

Accepted Answer

While antioxidants may have some health benefits, studies have not shown consistent evidence that antioxidant supplements can lower rates of death from heart disease or cancer. In fact, some studies have shown negative effects on health outcomes. It is generally recommended to get antioxidants from a balanced diet that includes fruits, vegetables, and whole grains.

Question 3

The key to a successful Calorie-restricted diet is to&#10;A)consume 1,000 or fewer calories per day.&#10;B)consume a low-Calorie, high nutrient-dense diet.&#10;C)exercise at least one hour each day while eating fewer calories than usual.&#10;D)join a support group.

Accepted Answer

Consuming a low-Calorie, high nutrient-dense diet is the key to a successful Calorie-restricted diet as it ensures that the body still gets all the necessary nutrients while reducing overall calorie intake. Consuming 1,000 or fewer calories per day or exercising excessively can be harmful to the body and joining a support group may be helpful but is not necessary for success.

Question 4

Approximately how long would a person's life be prolonged if he or she did not start consuming a Calorie-restricted diet until the age of 55 years?&#10;A)4 months&#10;B)1 year&#10;C)5 years&#10;D)10 years

Accepted Answer

Calorie restriction started at age 55 is estimated to prolong life by approximately 4 months, as the benefits of calorie restriction on longevity are more pronounced when started earlier in life.

Question 5

Research studies indicate that consuming which of the following supplements can cause gastrointestinal upset?&#10;A)vitamin C&#10;B)ginseng&#10;C)gingko&#10;D)melatonin

Accepted Answer

The answer of Research studies indicate that consuming which of...

Question 6

An evaluation of the impact of a Calorie-restricted diet on health indicates only the calorie level of the diet and NOT the nutrient content that is critical to prolong life.

Accepted Answer

Both calorie level and nutrient content are critical factors in evaluating the impact of a calorie-restricted diet on health and longevity.

Question 7

Although promising, research that could precisely study and measure the benefits of a Calorie-restricted diet in humans may never be conducted because of logistical and ethical concerns.

Accepted Answer

Researchers would face ethical concerns for restricting the number of calories a person consumes, and it would be difficult to ensure compliance and maintain the long-term health of participants.

Question 8

A Calorie-restricted diet (CR) is defined as a diet containing 1,000 or fewer calories per day.

Accepted Answer

A calorie-restricted diet (CR) is generally defined as a diet that restricts calories below the usual daily intake, but the specific number of calories varies depending on factors such as a person's age, gender, weight, and activity level. A diet containing only 1,000 calories per day would be considered very low calorie and is not appropriate or safe for everyone.

Question 9

Preliminary research studies suggest that a Calorie-restricted (CR) diet can improve metabolic measures of health in humans and, therefore, may be able to extend the human life span.

Accepted Answer

Preliminary research studies have shown that a Calorie-restricted (CR) diet can improve metabolic measures of health in humans, including reducing blood pressure, cholesterol, and insulin levels. These improvements may contribute to a longer life span. However, more research is needed to confirm these findings and to determine the long-term effects of CR on human longevity.

Question 10

Which of the following metabolic effects of CR has NOT been reported in any of the human studies?&#10;A)increased energy expenditure&#10;B)a decreased fat mass and lean body mass&#10;C)decreased insulin levels and improved insulin sensitivity&#10;D)decreased core body temperature and blood pressure

Accepted Answer

Caloric restriction (CR) in human studies has not been reported to increase energy expenditure. Instead, it typically leads to decreased energy expenditure as the body adapts to lower caloric intake.

Question 11

Antioxidant supplements are not necessary and may actually be harmful.

Accepted Answer

The answer of Antioxidant supplements are not necessary and may...

Question 12

Which of the following is NOT a benefit of a Calorie-restricted (CR) diet?&#10;A)The reduced metabolic rate results in a significantly lower production of free radicals.&#10;B)The reduced caloric intake results in reduced oxidative damage to DNA and other cells.&#10;C)Caloric restriction causes marked improvement in insulin sensitivity.&#10;D)Calorie restriction results in decreased fat mass and increased lean body mass.
