Skipping Breakfast Doesn't Result in Energy Compensation
No or small increase in lunch intake resulting in overall reduction in total daily energy intake
FRIDAY, July 26 (HealthDay News) -- Skipping breakfast does not lead to energy compensation at lunch or later in the day, according to a study published in the July 2 issue of Physiology & Behavior.
David A. Levitsky, Ph.D., and Carly R. Paconowski, from Cornell University in Ithaca, N.Y., examined the effect of eating breakfast on subsequent energy intake. Participants who habitually ate or skipped breakfast were recruited for two randomized crossover design studies. In the first study, participants were randomized to consume either no breakfast, a high-carbohydrate breakfast (335 kcal), or a high-fiber breakfast (360 kcal); ad libitum intake was measured at lunch. In the second study, participants were provided a larger, normal-carbohydrate breakfast, consumed ad libitum (average intake, 624 kcal); food intake was measured throughout the day.
The researchers found that, in the first study, consumption at lunch was unaffected by eating breakfast or the kind of breakfast, although hunger ratings were reduced in the breakfast groups. In the second study, after skipping breakfast, hunger ratings and intake at lunch were significantly increased (144 kcal). The net caloric deficit was 408 kcal at the end of the day.
"These data are consistent with published literature demonstrating that skipping a meal does not result in accurate energy compensation at subsequent meals and suggests that skipping breakfast may be an effective means to reduce daily energy intake in some adults," the authors write.
