Scientists worked with 70 overweight and obese adults enrolled in the Veterans Affairs weight-loss program, MOVE!, and randomly selected half of them to receive tech-based support tools in addition to MOVE!’s usual health-education class. Over three months to one year, people in the tech group lost 7 lbs more, on average, than people just attending classes – even though almost everyone in the study was computer-illiterate when the program began. People in the tech group were also almost four times as likely to have lost at least 5% of their body mass after six months, and twice as likely to have maintained a weight loss of that amount after one year.

The right sunglasses can protect your eyes and look cool at the same time. This being the 21st century, select shades are socially conscious, too. Portland brand Shwood uses wood and other natural materials and manufactures locally. Founded by Ann Sacks, the brand Fetch dedicates a portion of its profits to animal welfare.
