Diabetes patients who skip breakfast and fast until noon may have major blood sugar spikes throughout the day, new research warns.

According to a new study conducted by Tel Aviv University researchers, skipping breakfast and being on an empty stomach till noon triggers major blood sugar spikes and impairs the insulin responses of Type-2 diabetics throughout the day.

 Researcher Daniela Jakubowicz, a professor at the Tel Aviv University, Israel, explained that for type-2 diabetes patients , the omission of breakfast is associated with a significant increase in all-day blood sugar spikes and of HbA1C, which represents average blood glucose levels over the preceding three months.

Researchers observed 22 Type-2 diabetics who averaged 56.9 years old, with a mean body mass index of 28.2 kg/m2. Over the course of two days, the participants consumed precisely the same number of calories and the same balanced meal for lunch and dinner. But on the first day they were made to eat breakfast, while on the second day they were made to fast until noon.

It was found that, on the days the participants skipped breakfast, they experienced extraordinary glucose peaks of 268 mg/dl (milligram per decilitre) after lunch and 298 mg/dl after dinner. However, the blood glucose levels spiked to only 192 mg/dl and 215 mg/dl after lunch and dinner respectively on the days when they did not skip breakfast.

The study concluded that reducing the amount of starch and sugars in lunch and dinner may not have an effect on reducing elevated glucose levels if diabetic individuals skip breakfast, explained Jakubowicz.

The researchers claimed that the fluctuation happens because of the fact that pancreatic beta cells, which produce insulin, forget their role with the increasing time difference between one’s evening dinner and the next day’s lunch. Also fasting until lunch increases the fatty acids in the blood which renders insulin ineffective in reducing blood glucose levels.

The findings were detailed in the journal Diabetes Care.
