A 'more breakfast and less dinner' diet doesn't change your calorie consumption, so why do experts recommend this eating style?

Many people who are highly interested in health and diet have heard the story that ``If you take in a lot of calories early in the day and fewer calories in the evening, you will lose weight.'' Should be. A new study that closely controlled participants' diets found that the diet did little to increase calorie consumption. On the other hand, experts report that they're also discovering important benefits that may lead to weight loss.

Weight loss: the time of day you eat your biggest meal has little effect – new study

A study on the timing of meal intake conducted in 2013 became the basis for the diet method of `` eating a lot in the morning and eating sparingly at night ''. In this study, which analyzed the relationship between meal intake timing and calorie consumption based on meal records and sleep time questionnaires submitted by participants, people who ate their main meal late lost weight more than those who ate early. suggested not.

Because the human body operates in a cycle called the circadian rhythm , and most biological functions, including metabolism, are regulated along this cycle, it is possible to eat more calories in the morning, when the day begins, and go to sleep. There is a certain persuasive power to the idea that you should eat less before eating.

To test this hypothesis, a research team led by Leonie C. Ruddick-Collins of the University of Aberdeen, Scotland conducted a study in which 30 participants were strictly controlled for four weeks. Participants were divided into a group that ``eats more in the morning and less at night'' and a group that ``eats less in the morning and more at night'', and all meals including lunch were provided by the research team. . In addition, all participants who ate something other than the prescribed meal were reported, and all leftovers were weighed and recorded.

The research team initially thought that ``the group that eats a larger breakfast and a smaller dinner consumes more calories and loses weight.'' However, when comparing the resting basal metabolic rate, activity, and total energy consumption calculated from water consumption, there was no difference in calorie consumption between the two groups, and the amount of weight loss was almost the same. . In addition, tests to check blood insulin, lipids, and blood sugar levels were also conducted, but there was no difference in these data.

In this study, not only the weight and calories burned, but also the hunger felt by the participants was measured. The research team measured and compared the hunger of the participants with a method called a

visual analog scale , which was originally devised as a measure of patient pain, and found that the participants in the group who ate a lot in the morning felt hunger throughout the day. It turns out that there are few.

From this result, the research team concluded, ``The only differences we saw in our study were self-reported hunger and appetite. This effect is thought to be useful for people aiming to lose weight, as it leads to better control of hunger and less food intake.'
