"The confirmation among a new set of patients that fasting is associated with lower risk of these common diseases raises new questions about how fasting itself reduces risk or if it simply indicates a healthy lifestyle."

Bolding mine. Correlation is not causation.

That is correct - but at the same time, you should also remember that the strongest correlations are the most likely causes. Obviously, a single instance of correlation between two different observations doesn't necessarily mean that there is a definitive causal link between the two, but if a correlation shows up over and over again, consistently, then it can be reasonably suggested or implied that that is the most likely cause. In other words, the greater the strength of a correlation - "strength" being the number of times that a correlation occurs - the more justified it becomes for us to think that the correlation implies causation even though it may not necessarily prove that 100%.

Wrong. Strength of correlation indicates nothing about its probability of being the cause, because correlation cannot distinguish between causative relationships and spurious relationships caused by confounding factors.

And that was specifically the point of the author of the article.

Even if 100% of all drownings occur when ice cream trucks are circulating the neighborhood, it does not demonstrate that the circulation of ice cream trucks is the cause of those drownings, or even a likely cause.
