Despite the fact that many studies have previously demonstrated the benefits of a high-caloric breakfast for weight loss and to regulate the glucose metabolism, very little was known regarding the effect of skipping breakfast on glycemic spikes after meals throughout the entire day. It is quite remarkable that, for type-2 diabetic individuals, 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, Medical Xpress said.
The clinical study was conducted on 22 type-2 diabetics who averaged 56.9 years old, with a mean body mass index (BMI) of 28.2. Over the course of two days, the participants consumed precisely the same number of calories and the same balanced meal — milk, tuna, bread, and a chocolate breakfast bar — for lunch and dinner. The only difference was that one day they ate breakfast and the second day they fasted until lunch.
Researchers theorized that the omission of breakfast would not be healthy, but it was surprising to see such a high degree of deterioration of glucose metabolism only because the participants did not eat breakfast. They found that participants experienced extraordinary glucose peaks of 268 milligram per decilitre after lunch and 298 milligram per decilitre after dinner on days they skipped breakfast, versus only 192 milligram per decilitre, and 215 milligram per decilitre after eating an identical lunch and dinner on days they ate breakfast.
This means that reducing the amount of starch and sugars in lunch and dinner will have no effect on reducing elevated glucose levels if diabetic individuals also skip breakfast.
