Keto Diet Standards and Regulations 2 — Questions and Answers
Question 1: Under FDA regulations, how must a food product label the term 'ketogenic' or 'keto-friendly'?
- As a strictly defined nutrient content claim
- As an informal marketing term with no regulated definition (Correct answer)
- Only if the product contains MCT oil
- Only if approved by a registered dietitian
Correct answer: As an informal marketing term with no regulated definition
The FDA has not established an official regulatory definition for 'ketogenic' or 'keto-friendly,' so these terms function as unregulated marketing claims.
Question 2: Which federal agency oversees labeling regulations for dietary supplements marketed for ketosis support?
- USDA
- DEA
- FDA under DSHEA (Correct answer)
- FTC under the Clayton Act
Correct answer: FDA under DSHEA
Dietary supplements, including those marketed for ketosis support, are regulated by the FDA under the Dietary Supplement Health and Education Act (DSHEA) of 1994.
Question 3: When a keto product claims 'net carbs,' what does current US regulation require manufacturers to do?
- Subtract only fiber from total carbohydrates
- Get FDA pre-approval for the net carb calculation
- Use a standardized FDA-approved net carb formula
- Calculate net carbs independently since FDA has no official definition (Correct answer)
Correct answer: Calculate net carbs independently since FDA has no official definition
The FDA does not have an official definition or required formula for 'net carbs,' so manufacturers calculate and use the term at their own discretion.
Question 4: A company wants to claim its product 'supports ketosis.' Under FTC guidelines, what must they have before making this claim?
- Approval from the American Ketogenic Society
- Competent and reliable scientific evidence (Correct answer)
- A patent on the ketosis-supporting ingredient
- Endorsement from a licensed physician
Correct answer: Competent and reliable scientific evidence
The FTC requires that health-related advertising claims be backed by competent and reliable scientific evidence before they can be made to consumers.
Question 5: Which of the following best describes how the US dietary guidelines currently view very low-carbohydrate ketogenic diets?
- They are officially endorsed as a primary weight-loss strategy
- They are not included as a recommended dietary pattern (Correct answer)
- They are recommended only for athletes
- They are classified as a medically necessary diet
Correct answer: They are not included as a recommended dietary pattern
The 2020–2025 Dietary Guidelines for Americans do not include or recommend very low-carbohydrate ketogenic diets as a standard dietary pattern.
Question 6: For a therapeutic ketogenic diet prescribed for epilepsy, which professional body's guidelines are most commonly followed in the US?
- American Heart Association
- International League Against Epilepsy (ILAE) (Correct answer)
- American Diabetes Association
- Academy of Nutrition and Dietetics only
Correct answer: International League Against Epilepsy (ILAE)
The ILAE has published consensus guidelines for the use of dietary therapies, including the ketogenic diet, for epilepsy management.
Question 7: What requirement does the FDA impose on food products that voluntarily display nutrition information per a 'keto serving'?
- The serving must be approved by a keto certification body
- The nutrition facts panel must still comply with FDA's standard serving size regulations (Correct answer)
- They must include a disclaimer approved by the FTC
- They must list net carbs as a mandatory nutrient
Correct answer: The nutrition facts panel must still comply with FDA's standard serving size regulations
Regardless of any keto-specific marketing, all food products must display a Nutrition Facts panel that complies with FDA's established serving size and labeling regulations.
