Losing weight by defaecating at night theory: The gastroenterologists' perspective.

摘要

We read with surprise the correspondence piece by Drs. Aziz from the Department of Neurology in Leiden University , who proposed to defaecate at night in order to Lose weight. If their hypothesis was correct then obesity would have been less frequent among people suffering from chronic constipation, because, according to the theory of Drs. Aziz, they should have higher energy expenditure as they always carry out their everyday activities "with a few extra ounces of luggage" and their appetite should be decreased owing to a nearly full colon. However, epidemiologic studies prove just the opposite, showing an association between chronic constipation and obesity .
