Skipping breakfast is bad for health, says a new research. In the study, women who did not have breakfast had higher spikes in insulin and glucose levels after lunch when compared with the women who only had water in the mornings. The result was shared by Elizabeth Thomas, MD, of the University of Colorado’s School of Medicine in Aurora.
An increase in the level of free fatty acids was also seen, since lipolysis was occurring.
"It's possible that insulin resistance over time may predispose to further metabolic derangements and possibly progression to type 2 diabetes," said Thomas.
Lisa Fish, MD, an endocrinologist practicing in Minneapolis and a member of the society's Advocacy and Public Outreach Core Committee, said, "Learning about these mechanisms does give us better data to recommend eating habits to people, and I think our society is having trouble with eating habits."
Fish also said, "People may be doing that to try and eat less but they end up with a dysfunctional use of fuel for their bodies that causes them to actually gain more weight and develop more insulin resistance."
She further said many people only have two proper meals a day and then only take snacks for the rest.
Around 10% to 20% don’t have breakfast and this results in higher body mass index (BMI) in both youngsters and adults alike.
Those who were thin and took breakfast regularly were, in the study, told to skip breakfast over a short period.
The results were impaired insulin sensitivity, no change or an increase in energy intake, increased hunger, decreased satiety and worse lipid profiles.
In the study performed on 10 women whose ages were 25 to 40 (mean 29) and who had a BMI of 27 to 35 kg/m2 (mean 31.4), eight out of ten had breakfast regularly and two regularly skipped the meal.
Results were that insulin increased to higher levels after lunch in women who did not eat breakfast. As for the free fatty acids, before lunch, these were higher in the no-breakfast group, and eating lunch resulted in a rapid drop.
