Australian researchers conducted meta-analysis studies of the benefits of taking breakfast for obesity prevention and found that those who missed breakfast were somewhat smaller by the end of observation and consumed less calories than those who did not miss breakfast. The article was published in the journal BMJ.
One of the best strategies for obesity prevention is a balanced diet as well as a proper schedule of food intake: for example, weight loss diet research advisers are advising you to postpone breakfast for a while and to eat dinner early. In addition, mandatory breakfast is generally considered to be one of the main rules for preventing excessive weight gain: it can not go to other meals, for example, speeds up metabolism before training, allowing you to spend more calories.
Despite the fact that a mandatory breakfast is a frequent recommendation of nutritionists and other experts, long-term studies that would clearly show benefit from its consumption of obesity prevention are rare. For their meta-analysis, scientists under the guidance of Katherine Sievert (Katherine Sievert) from Monash University have studied nearly two thousand scientific publications on this topic from 1990 to 2018: duplicates, summary reports from conferences, reviews and studies with juvenile participants. Scientists were also excluded from the working sample, where skipping of breakfast was not specified in the methodology, jobs that did not include weight as a dependent variable, and participants did not belong to developed countries. As a result, scientists managed to collect only 13 meta-analysis studies: another factor in the selection was the fact that all of the work fell under a randomized controlled trial. Total of these 13 studies involved 1,416 participants.
Scientists found that study participants who missed breakfast were about 0.44 pounds less than those who did not miss breakfast (the effect was noticeable but statistically insignificant); In addition, those who did not skip breakfast consumed 259.79 calories a day more than those who skipped it.
The authors explained that the quality of the studies involved in their analysis was low: mainly due to the small number of participants and the lack of data that could be used as important secondary variables. Therefore, according to them, it is not yet possible to overcome the benefits of weight loss; it is also impossible to confirm: for this, it is necessary to carry out a better research on this issue in the future.
However, in other studies, scientists make conclusions about the health benefits of breakfast. This, for example, refers to atherosclerosis, whose risk increases by systematic overcrowding.
