WAHINGTON — People with Type 2 diabetes who eat breakfast later, are more likely to have a higher Body Mass Indices (BMI).
According to a study conducted by the University of Illinois at Chicago, an ‘evening person’ is linked to higher body mass indices among people with Type 2 diabetes, and having breakfast later in the day seems to be what drives this association.
Obesity is common among people with Type 2 diabetes. Having an evening preference — waking up later and going to bed later — has been linked to an increased risk for obesity, but research is lacking regarding this phenomenon among people with Type 2 diabetes.
Researchers, led by Sirimon Reutrakul, wanted to determine if morning or evening preference among people with Type 2 diabetes was associated with an increased risk for higher BMI and if so, what specific factors about evening preference contributed to the increased risk.
Reutrakul and her colleagues recruited 210 non-shift workers living in Thailand with Type 2 diabetes for their study. Morning/evening preference was assessed using a questionnaire that focused on preferred time for waking up and going to bed; time of day spent exercising; and time of day spent engaged in a mental activity (working, reading, etc.).
Participants were interviewed regarding their meal timing, and daily caloric intake was determined via self-reported one-day food recalls. Weight measurements were taken and BMI was calculated for each participant. Sleep duration and quality were measured by self-report and questionnaire.
Self-reported average sleep duration was 5.5 hours/night. On average, participants consumed 1,103 kcal/day. The average BMI among all participants was 28.4 kg/m2 — considered overweight. Of the participants, 97 had evening preference and 113 had morning preference.
Participants with morning prefereEarly breakfast is important for people with Type 2 diabetesnce ate breakfast between 7 a.m. and 8:30 a.m., while participants with evening preference ate breakfast between 7:30 a.m. and 9 a.m.
Participants with morning preference had earlier meal timing, including breakfast, lunch, dinner and the last meal.
The researchers found that having more evening preference was associated with higher BMI. Caloric intake and lunch and dinner times were not associated with having a higher BMI.
Morning preference was associated with earlier breakfast time and lower BMI by 0.37 kg/m2.
“Later breakfast time is a novel risk factor associated with a higher BMI among people with Type 2 diabetes,” said Reutrakul. “It remains to be investigated if eating breakfast earlier will help with body weight in this population.”
Reutrakul speculated that later meal times may misalign the internal biological clock, which plays a role in circadian regulation.
The findings from the study are published in the journal Diabetic Medicine.
Adding glass of milk in breakfast can lower blood glucose
Several research studies have attempted to find a link between drinking milk and a reduced risk for experiencing type 2 diabetes and a new research has found that adding a glass of milk in breakfast is the perfect energy boost for body needs to get through the day.
According to a study published in the Journal of Dairy Science, consuming milk with breakfast cereal reduced postprandial blood glucose concentration compared with water, and high dairy protein concentration reduced postprandial blood glucose concentration compared with normal dairy protein concentration.
H Douglas Goff, PhD, and the team of scientists from the Human Nutraceutical Research Unit at the University of Guelph, in collaboration with the University of Toronto, examined the effects of consuming high-protein milk for breakfast on blood glucose levels.
The high-protein treatment also reduced appetite after the second meal compared with the low-protein equivalent.
“Metabolic diseases are on the rise globally, with type 2 diabetes and obesity as leading concerns in human health. Thus, there is an impetus to develop dietary strategies for the risk reduction and management of obesity and diabetes to empower consumers to improve their personal health,” Goff and his team noted.
Although the team only found a modest difference in food consumption at the lunch meal when increasing whey protein at breakfast, they did find that milk consumed with a high-carbohydrate breakfast reduced blood glucose even after lunch, and high-protein milk had a greater effect.
Milk with an increased proportion of whey protein had a modest effect on pre-lunch blood glucose, achieving a greater decrease than that provided by regular milk.
Likewise, a 2014 study from Lund University in Sweden published in the American Journal of Clinical Nutrition found eating high-fat milk and yogurt reduces a person’s type 2 diabetes risk by as much as one-fifth.
Another study published in the 2011 American Journal of Clinical Nutrition tracked the relationship between a person’s dairy consumption during adolescence and their risk for type 2 diabetes as an adult. The researchers concluded that “higher dairy product intake during adolescence is associated with a lower risk of type 2 diabetes.”Follow @gorkhapost
