Have trouble calling it quits when it comes to a meal? Hook your plate up to Mandometer, a real device that tells you when to stop eating and when to slow down.
Invented by Dr. Louis Maletz, who, as it turns out, is the medical director of an eating disorders clinic, the Mandometer was actually designed to use on anorexics and bulimics who otherwise fool others and themselves into believing their food portions are too large. But it works on big, speedy eaters, too.
