In recent years, wearable smart devices have gradually become a fashion. According to Reuters, the latest research shows that for young people with long-term healthy diet and exercise programs, this wearable device may be just a display, at least for weight loss. In 24 months, the weight of the person using the wearable exercise tracker was reduced by 2.4 kg, which was lower than the reduced weight of the control group, which was tracked using the website.
"We shouldn't recommend everyone to buy wearable smart devices on the grounds of helping to lose weight," said John M. Jakicic, principal founder of the University of Pittsburgh Health and Physical Education.
"Of course, we can't tell you that wearable smart devices can't help to lose weight. Our research shows that this device has indeed changed some people," Jakicic said to Reuters Health Reporter in the email: "We need to do it later." In-depth study of how these devices are causing behavioral changes."
Researchers recruited 471 adults aged 18-35 in Pittsburgh who were overweight to moderately obese. Initially, the team conducted a weekly meeting to monitor weight changes and discuss diet and exercise strategies for weight loss. In the next year and a half, this reunion is changed to once a month, and the assistants of the experiment will make a phone call every month, and each week will send a message to the participants to assist them in timely weight loss activities.
All participants were set in advance for calorie intake goals, and they also reported calorie intake on a diary or online platform. They also have to perform moderate to strenuous exercise of 100 to 300 minutes per week as required.
Six months later, half of the participants began monitoring recipes and physical activity through a website, while the other half received an armband-type health device, BodyMediaFITCore. This device can record steps, sleep time and calorie burn, and sells for around $100.
Two years later, the average wearer of the wearables group lost 3.5 kilograms and the average weight loss of the website equipment was 5.9 kilograms.
According to JAMA (American Medical Association), the body composition, fitness, physical exercise and diet of the two groups were improved.
According to Gary Miller of the Wake Forest University's Department of Health and Exercise, this does not mean that the activity tracker is "ineffective." He did not participate in the study.
“The control group is not the same person in the strict sense,†Millar told Reuters Health Reporter. “There are many factors that affect weight loss. For those who want to lose weight through wearable devices, it’s hard to say that these devices are useless or It is not necessary."
He also said that the effect that wearable devices can achieve is not just to lose weight. "If the wearable device gives you the motivation to exercise, then I think it's also valuable, but if it's a fashion logo or something to show, it doesn't make sense." He thinks so.
“We know that monitoring exercise behavior and diet is important for successful weight management. It is more conducive to improving the success rate by turning these theoretical things into reality in a simpler way.â€
He also recommends that if you want to manage your weight better, you need to take the right amount of calories and exercise for 30 to 60 minutes a day to moderate exercise, such as walking or other activities that are easy to do in your daily life.
“If these wearables can help you do that, then of course it’s perfect,†Jakiic said. “But you need to use technology in ways that will help you.â€
