According to the research, people who ate more in the morning reported feeling less hungry during the day, which could help with weight loss due to increased satiety.
Despite the well-known dietary strategy that optimizes the consumption of most of the daily calories at breakfast weight lossburning calories more efficiently and quickly, new study published Friday 9 in the scientific journal Cell metabolism reveals that having a person eat their largest meal early in the morning or in the evening does not affect how their body metabolizes calories. That is, there are no differences in energy expenditure and calories are burned equally.
However, according to the research, people who ate more in the morning reported feeling less hungry during the day, which could help with weight loss due to increased daily satiety.
For the study, researchers from the University of Aberdeen in Scotland were recruited 16 men And 14 women healthy, around the age of 50, overweight or obese to control diet and evaluate metabolism over time. Each participant was randomly assigned to eat a rich diet in the morning or evening for four weeks. The diets were isocaloric, with a balanced balance of 30% protein, 35% carbohydrate and 35% fat.
“There are many myths about when to eat and how it can affect body weight or health. This was largely driven by the field of circadian rhythm. But we in the field of nutrition wondered how this could be possible. Where would that be. ‘energy go? We decided to take a closer look at how time of day interacts with metabolism, ”says Alexandra Johnstone, one of the study’s authors and a researcher in appetite control at the Rowett Institute. University of Aberdeen, according to the publication. to the Daily science.

During the diet, participants in one group ate 45% of their daily calories at the first meal of the day, while the other group consumed the same amount at dinner. After the four weeks, the researchers found that energy expenditure and total weight loss were the same for both diets. The subjects in the big breakfast group lost 3.33 lbs over the four weeks, while the participants on the heavy night diet lost 3.38 lbs.
Another point analyzed was in relation to appetite. “Participants reported that their appetites were better controlled on days when they ate a bigger breakfast and felt full for the rest of the day,” said Alexandra, who she believes can be quite helpful in a “real” environment. . “, compared to the research scenario they were working on.
“There were no differences in total daily energy expenditure or resting metabolic rate related to timing of calorie distribution and no difference in weight loss. Participants who consumed the loaded diet in the morning reported significantly less hunger load. morning (great breakfast) can aid adherence to the weight loss regimen through increased appetite suppression.

Search limits
A limitation of the study is that it was conducted under free-living conditions and not in the laboratory. Furthermore, some metabolic measures were only available after breakfast and not after dinner.
according to Daily sciencethe researcher at the University of Aberdeen believes this type of experiment can be applied to the study of intermittent fasting – also called time-limited feeding – to help determine the best time of day for people on this type of diet to consume calories.
In this way, the researchers intend to extend research to analyze how the time of day affects metabolism. According to the researcher, it is possible that these individuals have different metabolic responses due to the disruption of their circadian rhythms, which are the mechanisms by which the organism of the organism regulates itself between day and night. / With international agencies
