Keto Quiz
Questions: 16 · 10 minutes
1. A person on keto is constipated and has been eating mostly meat, cheese, and butter. Which adjustment most directly addresses a likely dietary contributor?
Include suitable fiber-rich foods such as leafy vegetables, chia, or flax while maintaining adequate fluids.
Add more cheese because dairy fat stimulates intestinal movement.
Remove all vegetables to reduce digestive workload.
Replace water with unsweetened coffee throughout the day.
2. Which condiment is most likely to add a substantial amount of carbohydrate if its label is not checked?
Sweetened barbecue sauce
Extra-virgin olive oil
Plain mustard
Distilled vinegar
3. A person with diabetes has high ketones along with persistent vomiting, abdominal pain, confusion, or deep rapid breathing. What should they do?
Wait until the next scheduled meal to see whether the symptoms pass.
Exercise vigorously to use the circulating ketones faster.
Seek urgent medical help because these can be warning signs of diabetic ketoacidosis.
Treat the symptoms as an expected sign of entering nutritional ketosis.
4. After several weeks of carbohydrate restriction, a person's urine ketone strip becomes lighter even though their routine is unchanged. What is the best interpretation?
The lighter color proves that carbohydrate intake has increased.
The strip gives an exact measurement of how much body fat was burned that day.
Urine strips reflect excreted acetoacetate and can vary with hydration and adaptation, so color is not an exact measure of fat loss.
The result means blood glucose must be dangerously low.
5. A person taking insulin plans to begin a very-low-carbohydrate diet. What is the most important first step?
Keep every medication dose unchanged until measurable ketones appear.
Stop insulin on the first day because carbohydrates will no longer raise blood glucose.
Discuss the change with the prescribing clinician because medication needs and hypoglycemia risk may change.
Replace glucose monitoring with urine ketone testing.
6. Which statement best describes protein in a well-planned ketogenic diet?
Protein must be kept near zero because any amount immediately stops ketosis.
Protein needs disappear once the body begins using more fat for fuel.
Protein is the diet's primary source of ketones and should replace nearly all fat.
Adequate protein supports muscles and other tissues, but keto is not necessarily an unlimited-protein diet.
7. At a restaurant, which order is the clearest low-carbohydrate choice without requiring major assumptions about ingredients?
A fruit smoothie made with banana, dates, and sweetened yogurt
Breaded chicken with coleslaw and a honey-mustard glaze
A bean burrito bowl with rice, corn, and tortilla chips
Grilled salmon with non-starchy vegetables, with any sweetened sauce served separately
8. Someone remains in nutritional ketosis but their body weight has stopped decreasing. Which conclusion is most accurate?
Ketosis does not remove the influence of energy intake, activity, water shifts, sleep, or other factors on body weight.
Measurable ketones guarantee continuous fat loss, so the scale must be wrong.
A plateau proves that the body can no longer use fat for energy.
The only possible explanation is hidden sugar in every meal.
9. Which method gives the most direct quantitative snapshot of the main ketone circulating in blood?
A blood meter measuring beta-hydroxybutyrate
A urine strip measuring excreted acetoacetate
A continuous glucose monitor measuring interstitial glucose
A breath device measuring acetone
10. What metabolic change is central to nutritional ketosis?
The pancreas stops producing insulin so that dietary fat can enter cells.
The liver increases ketone production as carbohydrate availability falls and fat use rises.
The body converts nearly all dietary protein directly into ketones.
The digestive system prevents carbohydrates from being absorbed.
11. Which group provides mostly unsaturated fat choices that can fit a ketogenic eating pattern?
Butter, bacon, coconut oil, and heavy cream
Olive oil, avocado, walnuts, and salmon
Margarine pastries, shortening, and deep-fried packaged snacks
Low-fat crackers, sweetened cereal, and fruit juice
12. Which meal is most consistent with a typical well-formulated ketogenic approach?
Whole-grain pasta with tomato sauce, chickpeas, and a small salad
Grilled chicken with brown rice, black beans, and corn salsa
Salmon with olive oil, leafy greens, avocado, and roasted zucchini
Fruit yogurt with granola, banana, and a drizzle of honey
13. A food label lists 15 grams of total carbohydrate and 7 grams of dietary fiber per serving. Using the common total-carbohydrate-minus-fiber calculation, how many grams remain?
7 grams
8 grams
15 grams
22 grams
14. How does nutritional ketosis differ from diabetic ketoacidosis, or DKA?
Nutritional ketosis occurs only in people with diabetes, while DKA occurs in everyone else.
Nutritional ketosis is a regulated metabolic state; DKA involves dangerous acidosis and requires urgent medical care.
They are the same condition, with the name determined only by the ketone level.
DKA is a normal stage of adapting to a ketogenic diet.
15. A few days after sharply reducing carbohydrates, someone develops headache, cramps, and lightheadedness. Which response is most appropriate?
Assume the symptoms confirm successful ketosis and ignore them.
Drink less fluid so the kidneys retain more minerals.
Add a large amount of sugar without considering other possible causes.
Recognize that fluid or electrolyte shifts may contribute, hydrate appropriately, and seek clinical guidance if symptoms persist or are severe.
16. Someone loses several pounds during the first week of sharply reducing carbohydrates. What most reasonably explains much of this early change?
Dietary fat temporarily passes through the body without being absorbed.
Muscle tissue is rapidly converted into energy regardless of protein intake.
Ketones themselves have substantial weight and are removed through urine.
Using stored glycogen releases associated water, so early loss is not necessarily all body fat.
