Epidemiological studies have shown that breakfast abstinence is associated with a risk of type 2 diabetes. However, it has never been possible to demonstrate in what context this is related to obesity. Obesity is an important risk factor for the onset of type 2 diabetes. It has been shown that obese people often abstain from breakfast than normal people. In addition, breakfast abstinence is discussed with a weight gain.
The research team of Dr. Sabrina Schlesinger, chief of the Systematic Reviews of the Junior Research Group at the DDZ, compared men and women in six long-term studies, taking into account the body mass index (BMI). The results of the study show a dose-response relationship, i. As the amount of non-asleep breakfast increased, the risk of diabetes increased. The highest risk was observed to abstain from breakfast for 4-5 days a week. No increase of risk was determined from the fifth day after the absence of breakfast. "This relationship is due in part to the influence of overweight. Even after taking into account BMI, breakfast was associated with a higher risk of diabetes," explains Dr. Med. Sabrina Schlesinger.
In its meta-analysis, the research team summarized data from six international observational studies. In general, 96,175 participants were evaluated, of which 4,935 had diabetes during the course of the study. An explanation of the relationship between breakfast and the risk of type 2 diabetes can be a healthy lifestyle per se. Participants who lose their breakfast can usually have a less favorable diet, for example, by consuming calories that contain sandwiches and beverages, be less active or smoke more. However, these factors were included in the evaluation so that the observed relationship could be explained by other factors. "It is necessary to have more studies than, in addition to the elucidation of the mechanisms, also explore the influence of the composition of breakfast on the risk of diabetes," says Dr. med. Sabrina Schlesinger. "Basically, a regular and balanced meal is recommended for all people, with or without diabetes," says the epidemiologist and nutritionist.
