(2)A study by the University of Florida claims that putting mirrors in your dining room will help weight loss because they actually make junk food taste worse. The researchers asked 185 undergraduates to choose chocolate cake or a fruit salad and evaluate the taste.(1)Those who ate them in a room with a mirror scored the taste of the junk food lower than those in a room without one, but it had no effect on the fruit salad.
    Lead scientist, Dr. Ata Jami of the University of Central Florida, said, "A glance in the mirror tells people more than just about their physical appearance. It enables them to view themselves objectively and helps them to judge themselves and their behavior in the same way that they judge others." The mirrors were found to push the subjects to compare and match their own behaviors with accepted social standards.(2)When they look in the mirror while eating junk food, feelings of discomfort and failure are enhanced.
