I think eating breakfast will not help, if your breakfast is made of big mac, three cheesburgers, fried potatoe and a big coke portion...

I also wager that folks who eat breakfast get up earlier in the day than people who do not.

Thank You Sal!

@SEThatered Hmmm, well I am sure as sure can be that the SS grammar Nazi (with his ironically imperfect grammar) is a troll. I feel it should be said that the defense 'I'm using the internet as my medium of communication' is a little...absurd.
Questions are provoked from such a stance, I certainly do not percieve it to be a valid or even semi-defensible position to take. Is there a good reason not to strive for good grammar? Why is it stronger when using the internet? Not to cause an argument.

Great video Sal!
More about reading research papers please!
Even the same topic with a different example would be good.
Cheers!

No, that text does NOT imply causality, except for the title.
That language is VERY WELL PHRASED to AVOID implying causality. Read more scientific papers and see this kind of language is employed in studies that show correlations.

@ZergAteu The researchers probably understand the difference and may have even been careful with their wording. The article, however, is clearly trying to have the reader walk away with the thought that eating breakfast makes obesity less likely.
