CE TEST QUESTIONS

GENERAL PURPOSE: To gain knowledge about the safety and efficacy of using intermittent fasting (IF) for achieving weight loss by reviewing relevant literature and study findings.

LEARNING OBJECTIVES: After completing this continuing education activity, you should be able to:

1. Explain the weight gain cycle, concepts such as hunger and appetite, and the physical effects that occur with IF.

2. Differentiate between the main types of IF diets regarding use, benefits, and disadvantages.

3. Summarize study findings regarding weight loss and safety and efficacy of IF diets.

  1. During the second stage of fasting, which lasts up to 18 hours, the fuel source that is used by the body is
    1. fat.
    2. alanine.
    3. glycogen.
    4. lactic acid.
  2. Which stage of fasting causes a metabolic switch that involves a mobilization of fat and then metabolizing it into fatty acid–derived ketones to provide energy?
    1. initial stage of fasting
    2. second stage of fasting
    3. third stage of fasting
    4. final stage of fasting
  3. When explaining the difference between hunger and appetite to a patient desiring weight loss, the provider explains that appetite is the
    1. desire to eat.
    2. physiological urge to eat.
    3. physiological anticipation of eating.
    4. drive to consume pleasure-inducing food.
  4. When explaining the weight gain cycle to an individual with obesity, the provider describes the concept of hedonic hunger, which stems from the hormonal regulation of leptin and
    1. gastrin.
    2. insulin.
    3. ghrelin.
    4. cortisol.
  5. The periodic fasting diet is explained to an individual with hypertension, high lipid levels, and type 2 diabetes. The provider states that this type of IF
    1. has beneficial effects on lipid profiles.
    2. is safe to use for people with type 2 diabetes.
    3. has shown conflicting findings on effects on blood pressure.
    4. can lead to increases in fasting glucose and insulin resistance.
  6. When counseling an individual about alternate-day fasting, the provider explains that this method of IF
    1. has an increased risk of disordered eating.
    2. is more effective when combined with exercise.
    3. increases cardiovascular and metabolic biomarkers.
    4. includes fasting for a 16-hour period and then eating food for 8 hours per day.
  7. The older adult individual desires to try a popular IF diet that he heard improves sleep, is feasible for older adults, and leads to weight loss, which is called the
    1. juice fasting diet.
    2. fast-mimicking diet.
    3. alternate-day fasting diet.
    4. time-restricted feeding diet.
  8. An adult male has been on a juice fasting diet because his wife thought it would improve their health. The provider explains to him that
    1. studies show improvement in sleep.
    2. this diet reduces C-reactive protein levels.
    3. it is associated with a significant decrease in triglycerides.
    4. there is no scientific evidence to support any health claims on this diet.
  9. An adult female explains that she will begin a religious assumption fast that includes abstaining from dairy products, eggs, and meat for 15 days, which is a type of
    1. Jewish fast.
    2. Daniel fast.
    3. Ramadan fast.
    4. Greek Orthodox fast.
  10. When a 3-week study used the alternate-day fasting diet for overweight men and women, it was found that both overweight men and women showed a (an)
    1. impaired glucose uptake.
    2. improved insulin sensitivity.
    3. remarkable decrease in insulin response.
    4. exacerbation of insulin resistance in skeletal muscle.
  11. Clinical trials using periodic fasting and time-restricted feeding showed that this type of fasting may
    1. increase atherosclerosis.
    2. reduce insulin sensitivity.
    3. increase cardiovascular risk factors.
    4. decrease the risk of coronary artery disease.
  12. A study investigating IF included overweight men and women using either the continuous energy restriction diet or the periodic fasting diet and found they had
    1. better nutrition.
    2. poor eating behaviors.
    3. an average of 14-kg weight loss.
    4. increased their total cholesterol levels.
  13. A 2-week study using the time-restricted feeding diet investigated if there was an association between the IF regimen and peripheral glucose uptake and hepatic insulin sensitivity. The study showed
    1. no association.
    2. a small increase in peripheral glucose uptake.
    3. a significant decrease in hepatic insulin sensitivity.
    4. improvement in both peripheral glucose uptake and hepatic insulin sensitivity.
  14. A meta-analysis on the effectiveness of IF diets for patients with diabetes, patients with prediabetes, and healthy individuals found that while on the IF diets, fasting blood glucose levels
    1. were higher in diabetics.
    2. decreased for healthy individuals.
    3. were lowered in patients with diabetes and patients with prediabetes.
    4. increased for patients with prediabetes and healthy individuals.
  15. A patient asked the provider about IF with preexisting disorders. The provider explained that there were some small-scale clinical studies that suggest that IF may have
    1. beneficial effects for bone health.
    2. a disadvantage for those with chronic pain.
    3. minor beneficial effects on mood disorders.
    4. slightly increased adverse effects of chemotherapy agents.
  16. Two studies that tested the metabolic effects of IF on nonobese subjects over 14 to 21 days with a high dietary intake on nonfasting days indicated that participants
    1. had complained of persistent hunger with IF.
    2. experienced hypophagia when allowed to eat again.
    3. maintained a normal appetite without hunger with IF.
    4. ate normal helpings of food when allowed to eat again.
  17. A female patient has been breastfeeding for the past 3 months and is trying to lose weight. She asks her provider about IF dieting. The provider states that using an IF diet

    2. is a good diet for her to use for health and weight loss.
    3. has no evidence-based data for making any recommendations.
    4. has no contraindications for lactating women, so it should be fine.

    1. increase dietary fat.
    2. reduce fiber intake.

    2. not enough data to show any consistent loss in weight.
    3. weight loss regardless of changes in overall calorie intake.
    4. no changes in weight regardless of following the IF diet directions.
