 Background: Skipping breakfast andor overeating at evening, has been associated in type 2 diabetic T2D individuals, with higher BMI, visceral adiposity, hyperlipidemia, increased overall postprandial glycemia PPHG and higher HbA1c. The absence of breakfast is also associated with increased plasma free fatty acids FFA along the morning until lunch. High plasma FFA in turn are triggering factor of insulin resistance, by inhibiting insulin mediated glucose uptake in obese and T2D subjects The investigators therefore hypothesize that compared to eating breakfast the prolonged overnight fasting caused by the breakfast omission will result in increased postprandial glycemic response after subsequent isocaloric lunch and dinner in T2D individuals.
