While I completely agree with the gist of the article, Dr Davys counter-argument is terrible:
"It is possible that the water displaced sugary drinks in the hydrated group, but this does not explain the weight loss because the calories associated with any fizzy drinks consumed by the other group had to fall within the daily limits."
There is such a thing as good calories and bad calories - obviously getting your calories from healthy fats such as olive oil and avacados is going to be a lot more beneficial to your weight in the long run than getting your calories from sugary fizzy drinks such as coca-cola.

Still, nice article.
