Blame your supermarket for leading you into temptation -- all those bakery goods, chips, dips, and beverages galore are bound to cause the best of us to cave on our best diet intentions. That's why we should order our groceries online, says a new multi-university study.

Researchers assigned 28 people to either a standard weight-loss program or a program with grocery delivery and found after eight weeks that online buyers had fewer fattening products and less total food in their cupboards.

The bottom line for your bottom line: Virtual shopping carts make it easier to stick to your list. They eliminate last-minute grocery store grabs too. So ditch the traditional cart and go online for for your food -- and for your body too.
