In 2007, Loic Le Meur and I came up with the concept of La Fatera. It is described here. The idea was a scale that would share your weight over the internet and help you lose weight socially. At that time the plan was that Fon makes the Fonera and the Fatera. But while at Fon we stuck with the Fonera, a successful strategy (this year alone we sold close to 2 million), others picked up on the concept of the Fatera. The most successful implementation is Withings the WiFi scale. And new social sites to lose weight keep appearing. Fatdrop is a good example.
The obvious reason for the success of the scale and the weight losing sites is the obesity epidemics. 20% to one third of the population of developed countries obese or overweight. Interestingly obesity is so global and popular that in the world now there are as many obese people as hungry people, an estimated billion of each. But other than obesity the psychology of overeating lends itself more to sharing the activity socially to stop it than other addictions. Drug addictions, alcoholism are generally treated in secret in places like AA because taking drugs alters your behavior and there is a shame factor associated with it. Few people tweet something like “I have gone 134 days without shooting heroin”. Yet many people are tweeting their weight with Bob Metcalfe the creator of ethernet is a good example. Over eating is an activity that can be done in public, without shame and that other than the occasional barfing it does not produce any obvious social problems (it’s legal to drive after you overeat for example). But in this case, the shamelessness nature of over eating is a big plus for society to get you to stop. And sharing your weight over the internet is the objective measure of your eating. I see tremendous potential in weight sharing as a way to socially lose weight.
