According to the JCEM, a larger breakfast is "preferred over large dinner meals to prevent obesity and high blood glucose peaks," because the amount of energy needed to process a meal is higher in the morning than at night.
Researchers looked at a pool of participants, one group who ate a larger breakfast and smaller dinner burned more than twice the number of calories as those who ate a large dinner and smaller breakfast.
Researchers put high importance to watch , however, that those who are looking to lose weight must also watch what they eat, not just when.
