7. Watch one less hour of TV


A study of 76 undergraduate students found the more they watched television, the more often they ate and the more they ate overall. 

Sacrifice one program (there’s probably one you don’t really want to watch anyway) and go for a walk instead—in even just 15 minutes, you’ll reap these amazing benefits of walking. 

And during your favorite shows, get off the couch and try these exercises you can do while watching TV.
