Weight loss can be enhanced with PDAs and apps: Study
REUTERS - Mobile devices that let people track how much they eat and exercise may help them shed weight over and above the benefits of a typical weight-loss program, according to a U.S. study.
Researchers writing in the Archives of Internal Medicine found that overweight and obese adults lost an average of over 3.6kg more when they had personal digital assistants (PDAs) and occasional phone coaching to help them, in addition to a group program.
There's no reason to think the same wouldn't hold true for smart phone apps that can log nutrition and activity information, and give real time feedback, they said.
"The number one mechanism through which people lost weight is self-monitoring, just watching what you eat and keeping a record of it," said Goutham Rao, who wrote a commentary published with the new study.
