It is every chocolate lover's dream- the ability to enjoy your favorite treats with zero guilt and that means zero calories. Enter, Le Whif, an inhaler developed by scientists to make that sweet dream come true. The revolutionary device that looks like a lipstick tube allows users to inhale chocolate instead of eating it to satisfy cravings. Invented by Harvard biomedical engineer David Edwards, Le Whif comes in four different flavors - raspberry, mint, mango, and plain. It costs around $2 for four 'whifs'. I plan on stashing a six pack in my purse.
