Australian researchers carried out a meta-analysis of studies on the benefits of breakfast to prevent obesity and found that participants who had lost breakfast were weighing less at the end of the observation and consumed fewer calories than those who did not miss breakfast. Article published in the journal BMJ.
One of the best strategies to prevent obesity is a balanced diet as well as the correct food intake timetable: Scientists, for example, about the influence of nutrition on weight changes, advise you to have breakfast for breakfast and eat before eating. In addition, a mandatory breakfast is basically considered one of the main rules to prevent overweight: it can not devote other meals, as it speeds up metabolism before training, allowing you to spend more calories.
Despite the fact that mandatory breakfast is a frequent recommendation of nutritionists and other experts, there are only a few long-term studies that show a clear benefit from their consumption to prevent obesity. For their meta-analysis, scientists led by Katherine Sievert of Monash University studied between 1990 and 2018 nearly two thousand scientific publications on the subject: duplicates, abstracts of news from conferences, reviews and studies with minors were excluded from them. Scientists were also excluded from the work sample, where the methodology did not specify spills that did not include weight as a dependent variable, and the participants did not belong to the developed countries. As a result, scientists were able to assemble only 13 studies of meta-analysis. Another factor in the selection was the fact that all the work fell under randomized controlled trials. Altogether, these 13 studies included 1,416 participants.
Researchers found that participants in the study who lacked breakfast weighed 0.44 kilograms less than those who did not miss breakfast (but the effect was noticeable but statistically insignificant); In addition, those who did not go to breakfast consumed 259.79 calories per day than those who skipped them.
The authors clarified that the quality of studies included in their analysis is low: primarily due to the low number of participants and the lack of data that could be used as important secondary variables. Therefore, according to them, it is not possible to disprove the benefits of weight loss breakfasts; can not be confirmed: for this, better research in this area is needed in the future.
In other studies, however, scientists draw conclusions about the benefits of breakfast. This is, for example, atherosclerosis, whose risk increases with systematic skipping of breakfast.
