This article says that we have no good actual scientific evidence of the importance of breakfast:

A study published last week in the American Journal of Clinical Nutrition starts with this simple fact—that in spite of all these association studies, no one knows exactly what skipping breakfast might be doing to our bodies. The study goes on to make a disturbing claim:
Scholars in this field of inquiry—breakfast science—have been fudging facts and misinterpreting the science.
The literature shows signs of research bias.

Apparently, there is a very strong link / association but no proof.

At least one-fourth of all the studies in their database made “unqualified causal claims” about their data, they said, and improperly declared that skipping breakfast actually causes obesity.
Another 25 percent hinted at a causal relationship with weasel phrases like “breakfast habits may contribute to obesity” or “the data suggest that it does.”

It’s also possible (but by no means certain) that breakfast improves cognitive abilities and mood in kids and teenagers.
