Autom™ is a robotic weight loss coach designed to help people who are trying to lose or keep off weight. Autom™ helps by encouraging you to stick with your diet for long enough to create long-term change and keep extra pounds off. Fifteen robots were used in a controlled clinical trial in the Boston area in the summer and fall of 2007. Results showed that people who worked with Autom™ stayed with their diet for twice as long as using a computer or paper-based diet log.
