Move More

Make it a daily thing to find ways to move your body.     1     Climb stairs instead of taking the elevator. Walk your dog. Play with your kids. It doesn’t have to be an hour in the gym or a 45-minute dance class. But that’s great when you’re up to it. At the same time, move more.

Quit Smoking

Ever since 1960 when it was announced that smoking was harmful to health, Americans have been reducing their use of tobacco products. Just recently, we’ve seen more and more teens smoking. Could it be the Hollywood influence?     2     Take care! Warn your children against smoking.

2 . A new study, a project of the researchers from the University of Pittsburgh in Pennsylvania, finds the fitness tracker probably does not help with weight loss.

The devices are designed to record your physical activity. They are usually worn around the wrist, where they measure a person’s heart rate. The research team looked at two groups of individuals. The first wore a fitness tracker and took part in health counseling (咨询) with experts to consider the best weight-loss plan. The researchers compared this group with people who only got health counseling.

The study found that those only speaking with the health experts lost nearly 6 kilograms, but those using a fitness tracker lost only 3.5 kilograms. John Jakicic, the lead researcher, questioned the use of electronic devices for weight control in place of “effective behavioral counseling for physical activity and diet. ”

The study involved 470 subjects aged between 18 and 35. Some of them were overweight, while others were considered obese (肥胖的). Over three fourths of the subjects were women. All the subjects were told to increase physical activity and start on a low-calorie diet. They had their weight measured once every six months. After six months, researchers divided the group into two parts: one continued with monthly counseling, while members of the other group were given a fitness tracker. Eighteen months later, both groups “showed significant improvements in fitness, physical activity, and diet,” with no major difference between groups. However, when it came to losing weight, the people who only spoke with experts lost nearly twice as much weight.

Jakicic said, “the study’s findings are important because effective long-term treatments are needed to address America’s obesity. ” More information is needed, he added, to learn how to best use these devices to change “physical activity and diet behaviors” in adults who want to lose weight.
