And Q—never a staff to skip a meal—lent our lips, for several unscientific weeks, to Too Faced Fuze Slenderize Guilt Free Gloss, which claims to "suppress your appetite."

A joint venture by Too Faced Cosmetics and Fuze Beverages, the gloss comes in three shades: Blueberry Raspberry, Strawberry Melon and Dragon Fruit Lime.

One Q staffer applied the gloss five times in 6 hours.

During that time, she thought about chocolate five times before she caved in to a bag of Almond M&Ms.

Other testers said the gloss did nothing for their cravings.

Yet, there is a reason to buy this product: The shiny, high-quality gloss looks wonderful on the lips.

The gloss ($18.50) is available at Sephora stores.
