Keen observation. Correlation does not imply causation. Do keep in mind though that this is an old article (2008). Followup studies have been conducted, such as "Treatment of childhood obesity by retraining eating behaviour: randomised controlled trial", by Ford et al.: http://www.bmj.com/cgi/content/abstract/340/jan05_1/b5388 http://www.bmj.com/cgi/content/abstract/340/jan05_1/b5388 Quote: "Conclusions: Retraining eating behaviour with a feedback device is a useful adjunct to standard lifestyle modification in treating obesity among adolescents." I have not read the whole article though, and some cautious scepticism is required as the authors seem to have commercial interests in the results :)
