Intermittent Fasting Quiz
Questions: 16 · 10 minutes
1. What does the common “5:2” intermittent fasting approach generally describe?
Five days of usual eating and two days with substantially reduced energy intake each week
Five hours of fasting followed by a two-hour eating window each day
Five fasting days followed by two unrestricted days each week
Five small meals on weekdays and two large meals on weekends
2. Someone has a current or past eating disorder and is interested in intermittent fasting. Which statement is most appropriate?
A rigid fasting schedule is useful because it removes all food-related decisions.
Fasting is suitable as long as the person avoids tracking body weight.
Extending the fasting window gradually eliminates the need for specialist input.
Fasting may reinforce harmful restriction, so guidance from an eating-disorder-informed professional is important.
3. Which drink is most reliably compatible with a calorie-free fasting window?
Plain water
Water mixed with honey and lemon
Coffee with a small amount of cream
A sugar-sweetened electrolyte drink
4. A pregnant person is considering starting intermittent fasting. What is the most appropriate first step?
Begin with a shorter fast and lengthen it if energy remains stable.
Move the fasting window to nighttime to reduce daytime hunger.
Discuss the plan with a qualified prenatal healthcare professional before fasting.
Add electrolyte supplements before trying the schedule.
5. Why should someone taking insulin or certain other glucose-lowering medicines consult a healthcare professional before fasting?
All glucose-lowering medicines must legally be taken at breakfast.
Fasting prevents every glucose-lowering medicine from entering the bloodstream.
Changing meal timing can raise the chance of dangerously low blood glucose and may require an adjusted care plan.
Fasting permanently removes the need to monitor blood glucose.
6. Which comparison between time-restricted eating and alternate-day fasting is accurate?
Time-restricted eating always skips breakfast, while alternate-day fasting always skips dinner.
Time-restricted eating uses recurring daily hours, while alternate-day fasting varies intake across different days.
Time-restricted eating permits caloric drinks while alternate-day fasting permits only solid food.
Time-restricted eating must use an eight-hour window, while alternate-day fasting must use exact 24-hour fasts.
7. A social-media post claims intermittent fasting always produces more weight loss than any other approach, even when overall energy intake is comparable. How should this claim be evaluated?
It is correct because meal timing always matters more than total intake.
It is correct for every fasting schedule lasting at least 12 hours.
It is correct because fasting makes consumed calories unavailable to the body.
It is overstated; intermittent fasting is one possible approach, and results often depend on intake, adherence, and individual circumstances.
8. What primarily distinguishes intermittent fasting from a diet that prescribes specific foods?
It removes most carbohydrate-containing foods from every meal.
It organizes recurring periods of eating and fasting rather than requiring a particular food list.
It requires all daily food to be eaten in one sitting.
It replaces solid meals with drinks during the eating period.
9. After a fasting period, which meal is the most balanced way to resume eating for many people?
A large portion of sweets because rapid sugar absorption is required
A moderate meal containing protein, fiber-rich foods, and fluids
Only a high-dose vitamin supplement until the next eating window
A very large fried meal to replace every calorie not eaten during the fast
10. During a fast, a person develops fainting, confusion, or chest pain. What should they do?
Stop fasting and seek urgent medical help.
Drink an electrolyte beverage and continue if the symptoms briefly ease.
End the fast and wait until a routine appointment to mention it.
Complete the fast but choose an earlier eating window the next day.
11. A medication label says to take each dose with food, but the scheduled dose falls inside a fasting window. What is the best response?
Move the dose into the eating window without mentioning the change.
Ask the prescriber or pharmacist before altering either the medication schedule or fasting plan.
Take the dose without food because maintaining the fasting window takes priority.
Skip that dose and resume the medication at the next planned meal.
12. Taylor wants to check whether caloric intake is actually confined to a planned daily window. Which record would be most useful?
A weekly list of body-weight measurements only
A list of foods Taylor considers healthy or unhealthy
The times of all meals, snacks, and calorie-containing drinks
The number of glasses of plain water consumed each day
13. Sam follows an eight-hour eating window but regularly consumes more total energy than before. Which conclusion is most accurate?
The shorter window will automatically offset the additional intake.
Any food eaten within the window stops contributing to weight change.
The schedule guarantees fat loss even if total intake rises.
The schedule alone does not guarantee weight loss because overall intake still matters.
14. Jordan finishes dinner at 8:00 p.m. and next consumes calories at noon the following day. How long was the fasting window?
12 hours
20 hours
18 hours
16 hours
15. As time passes after a meal and no more energy is consumed, which general metabolic shift occurs?
Insulin generally declines, and the body increasingly draws on stored energy such as glycogen and fat.
Insulin stays at its post-meal level until the next meal is eaten.
The body immediately stops using stored energy and relies only on dietary protein.
Metabolism switches off digestion and uses body fat as its only fuel source.
16. Riley wants to preserve muscle while combining intermittent fasting with resistance training. Which plan best supports that goal?
Avoid protein on training days so the fast has a stronger effect.
Replace resistance sessions with extra fasting days.
Continue resistance training and obtain adequate total protein and energy during eating periods.
Eat most food on rest days and train only near the end of the longest fast.
