A new study published in the journal Diabetic Medicine has unveiled the link between breakfast and obesity in type 2 diabetes.
The study notes that going to bed later is linked with obesity in people with type 2 diabetes, and the main factor that drives this relationship is eating breakfast later.
The research was led by Sirimon Reutrakul, who is an associate professor of endocrinology, diabetes and metabolism in the College of Medicine at the University of Illinois at Chicago.
Prof. Reutrakul suggests that eating later causes a shift in the biological clock that regulates day-night patterns. Other studies have proposed that this can disrupt energy metabolism.
In the study paper, Prof. Reutrakul and colleagues refer to research that indicates that a preference for later bedtime and meal times is linked to obesity but note that evidence of this is “lacking in people with type 2 diabetes.”
The researchers investigated how the following variables may relate to each other in people with type 2 diabetes: timing of meals, patterns of getting up and going to bed early and late, which the authors refer to as “morningness-eveningness preference”, body mass index (BMI), which was used as a measure of obesity
The researchers also ran a “mediation analysis” to determine whether morningness-eveningness preference “had a direct effect on BMI,” or whether timing of meals might be driving the effect indirectly.
210 working-age Thailand residents with type 2 diabetes who were not working shifts were enrolled in the analysis.

Type 2 diabetes accounts for the vast majority of diabetes cases. It develops when the body does not respond properly to insulin, which is a hormone made in the pancreas. Insulin helps cells to take in and use blood sugar for energy.
Obesity has been recognized as a risk factor for Type 2 diabetes with a majority of persons diagnosed with the disease.
The global obesity epidemic is considered the main reason that rates of diabetes have risen dramatically in the past 20 years.
