I can't find a clear source for Kellogg's coining that phrase, but they definitely use "The best way to start the day" as a slogan. For instance, this Kellogg promotional flyer: https://www.kelloggcompany.com/content/dam/kellogg-company/f...

Page three is what you want, and it's worth looking at for a masterclass in garbage science.

The big header gives us "A cereal breakfast. Why it’s the best way to start the day." The subhead asserts "Experts worldwide agree: Breakfast is the most important meal of the day", which is somewhere between disputable and a lie. Below that is a list of wild claims like "People who regularly eat cereal tend to be less stressed, less anxious and are less likely to be depressed."

Wow! Let's see the evidence! Well, about half the studies listed appear to be directly funded by Kelloggs. Many that weren't are about breakfast in general, so "eat cereal" is a misrepresentation of "compared to skipping breakfast and eating unhealthy snacks". And they're full of hilariously poor controls - there's some fumbling with "difficulty sleeping" and a "negative job score", but ultimately the study can't discern "the benefits of eating breakfast" from "the harms of working the night shift" or "leaving at 5AM in a rush".

It's actually fascinating just how many bold, impressive claims Kelloggs manages to make without lying while relying on laughably thin evidence.
