Yet eating a big breakfast instead of a larger meal later in the day did not impact weight loss, according to a new clinical trial that compared people eating most of their daily calories at breakfast with those eating the most at dinner.
"With calories either morning-loaded or evening-loaded, the researchers found nearly identical weight loss," said Katz, who was not involved in the study. In addition, "any magical effects" of early eating on the body's metabolism were debunked, he said, describing the research as "extremely rigorous."
"Thus, this study belies the contention that eating early alters metabolism in a way that favors greater weight loss." said Katz.
