You know how I can tell it's November Sweeps? Because Dr. Oz is talking about diet soda again. This time, he's taking it up a notch and claiming diet soda and low calorie sweeteners cause weight gain and cravings that adversely affect your metabolism.
And as usual, he did his best to dazzle (and scare) his audience with his Mr. Wizard breakdown of "science" and diet soda. Bubbles, a sugar hourglass of sorts, and stacking cups! Weeee!
He must be taking notes from David Blaine.
Of course, Dr. Oz won't mention that a review study published as recently as November 2013, found that diet beverages don't increase obesity risk and may in fact be helpful when used to replace higher calorie beverages. The authors of that study also note that many studies – such as the one he promoted – are totally biased because they are observational and that means that they cannot show cause and effect.
Anyways, the whole segment was just so far off base from everything I've ever read from credible studies on diet soda. And if any of what he was saying was true, I'd be gaining weight like crazy by now.
Here's a great breakdown of the segment by Registered Dietitian, Robyn Flipse (@EverydayRD) and The Skinny on Low Cal.
