What is the rationale for withholding feeding in end-of-life nutrition?

• A. Feeding even small amounts can prevent ketonemia and prolong hunger.
• B. Feeding would increase ketone production.
• C. Feeding accelerates fat loss.
• D. Feeding improves mood.

Answer: (A)

When nutrition is limited at the end of life, the body shifts into a fasting, fat‑burning state and ketone bodies become a major energy source. Providing any calories can blunt that ketogenesis by supplying glucose and other substrates, which changes the metabolic trajectory and can alter symptoms and resource use. The idea captured here is that even small amounts of feeding can prevent ketone production (ketonemia) and leave the patient in a different metabolic state. In some end‑of‑life care perspectives, this is why clinicians choose to withhold feeding—to avoid altering the natural catabolic process and associated symptoms. The other options don’t fit this metabolic rationale: feeding does not increase ketone production, feeding does not accelerate fat loss, and mood impacts are not the central rationale for this decision.
