SCIENCE, UNSETTLED: Skipping Breakfast Isn’t Actually Bad For You.

The idea that a hearty breakfast is good for your health dates back to the 1920s, when Edward Bernays, a public relations guru, led a nationwide media campaign encouraging people to start their mornings with bacon and eggs. One of Mr. Bernays’s clients at the time was Beech-Nut Packing Company, which sold bacon and other pork products.

In the decades that followed, dozens of observational studies reported that breakfast eaters tended to be leaner. Though these studies could not show cause and effect, many health authorities and food companies asserted that they proved that eating breakfast protects against weight gain.

But experimental studies that randomly assigned people to eat or skip breakfast have found no such thing.

So much “wisdom” on health and nutrition seems to be like this.
