How to kill two birds with one stone and feel great about it

Under the idea of “obesity is preventable, hunger is solvable,” Weightless Project combined wearable technology (Jawbone, Fitbit and Basis partnered with the project so far) to a pressing world problem of hunger. The solution is simple, as the great solutions often are: as your calories tick off on your wearable fitness tracker, donations pour in. More specifically though, the service works like this: you sign up on the site, and for every 1K calories burned, there is a $1 donation to the project’s food aid program of choice.
