The first group tracked the food that they ate for three months. The second group tracked body weight for a month and then began recording food intake. The group also received an email with personal comments, weekly lessons on nutrition and behavioral changes, and an action plan in which the weekly lessons were conducted.
The third group used the weight loss tracker as the first two groups to record their weight and food intake for three months. The study also included giving weekly lessons, action plans and feedback to the participants. These included tips on topics such as how to reduce eating sweets.
At the end of the research period, all of the participants in each group lost significant amounts of body weight. Those who recorded only what they ate lost about 5 pounds on average. Those in the second group lost an average weight of about 6 pounds.
Digital Activity Tracking Technologies
Besides weight loss trackers, digital activity trackers also seem to have weight loss benefits. Activity trackers, often worn around the wrists and hips, are designed to facilitate daytime movement. People who use these devices often are those who are physically active. However, these people do not always lose more weight than others.
A group of scientists designed a study to test whether activity trackers can help people lose weight. Study participants received weight management counseling which included diet and exercise. They also received telephone counseling, text messages, and access to online weight loss information. In just 6 months, they all lost a similar amount of weight.
