Full disclosure: I’m a Coke Zero guy. I drink one every day with lunch and am thus biased to some extent. I don’t get money from the industry – although I wouldn’t turn it down (in case the people at Coke are reading this). Even with my biases I think my assessment of the science on the connections between diet soft drinks and weight gain were accurate. It was clear that there was an association between drinking more and weighing more but it was far from clear the Diet Soda was causing weight gain. Overweight people drink more diet soft drinks for clear reasons. They also wear more extra large clothing but that doesn’t mean Joe’s Big and Tall Clothiers causes obesity.
