Is eating breakfast important for weight-management?

Take home message

As summarized by the American Institute for Cancer Research, "For those who don't like to eat breakfast, these studies do suggest that there's no harm for weight loss or metabolism in skipping that morning meal.  Many can find a way to take in all the nutrients and healthful plant foods, without overeating, that are part of a cancer protective diet."

Although there is a correlation between not eating breakfast and body weight, correlation doesn't prove causation.



Breakfast important

How scientists know

Health professionals noticed correlations between eating breakfast and health. So, they recommended eating breakfast.

But, the studies were correlations, which doesn't prove cause and effect. Did skipping breakfast cause health problems? Or was skipping breakfast an indication of an unhealthy lifestyle that lead to health problems?

The relationship of breakfast and cereal consumption to nutrient intake and body mass index: the National Heart, Lung, and Blood Institute Growth and Health Study. Journal of the American Dietetic Association, September 2005. Cereal consumption as part of an overall healthful lifestyle may play a role in maintaining a healthy BMI and adequate nutrient intake among adolescent girls.

BMI was lower for ready-to-eat-breakfast consumers than other breakfast consumers. Among Canadian adults, breakfast consumption was not consistently associated with differences in BMI.

Skipping breakfast was incompletely compensated lunch, breakfast increased some satiety hormones after lunch but abolished suppression of the orexigenic hormone gremlin, which may be mediated through reduced insulin response to a second meal.

There were no differences between groups I(eating or skipping breakfast) in weight change and most health outcomes, but insulin sensitivity increased with breakfast relative to fasting.
