Task: Answer Verification
Input (English): Question: Does fasting ghrelin predict food intake after short-term energy restriction?
Answer: Fasting ghrelin concentrations did not rise after a 2-day energy restriction regimen. Moreover, changes in ghrelin concentrations during energy restriction were not associated with subsequent ad libitum food intake, suggesting that fasting ghrelin does not act as a hunger signal to the brain. The data did not support our hypothesis that leptin suppresses ghrelin levels.
Output (English): no
