It was long said that if you wanted to lose weight it was best to eat a large meal at the beginning of the day and keep any later meals smaller.
The logic behind this theory is understandable, especially given that almost every cell in the body follows the same 24-hour cycle that we do. Circadian clocks are found throughout the body and regulate the daily rhythms of most of our biological functions, including metabolism.
Because of these metabolic rhythms, scientists have proposed that the way in which we process meals varies at different times of the day. This field of research is called "chrono-nutrition", and it has great potential for helping to improve people's health.
Two studies from 2013 suggested that consuming more calories early in the day and fewer calories in the evening helps people lose weight. Yet a major new study has found that while the relative size of breakfast and dinner influences self-reported appetite, it has no effect on metabolism and weight loss.
To investigate the link between the size of breakfast and dinner and their effect on hunger, a team of researchers at the universities of Aberdeen and Surrey conducted a controlled study in healthy but overweight people.
The participants were fed two diets, each for four weeks: a big breakfast and a small dinner, and a small breakfast with a big dinner. We kept lunches the same.
We provided all of the meals so we knew exactly how many calories study participants were consuming. We measured the participants' metabolism, including monitoring how many calories they burned.
All study participants undertook both diet conditions so that the effect of meal patterns could be compared in the same people. Read More…
