A new study finds that when people have monthly personal contact with a weight-loss professional, they’re able to keep off more weight.
Results of the study are published in the March 12 issue of the Journal of the American Medical Association and are to be presented that same day at the American Heart Association’s annual meeting in Colorado Springs, Colo.
Almost 1,700 overweight or obese people were recruited for the study. The first phase of the study was a six-month weight loss program. Groups of dieters met every week for group-based behavioral intervention treatment. Goals for treatment were 180 minutes of exercise each week, reducing caloric intake and adopting the DASH (Dietary Approaches to Stop Hypertension) diet. The weight loss goal per week was one to two pounds.
During the second phase, study volunteers were randomly assigned to one of three groups for maintenance — the “personal contact” group, the “interactive technology” group, and the “self-directed” group. The personal contact group was contacted 12 times each year by a counselor — three times in person and nine times by phone. The interactive technology group had unlimited access to a special weight-loss Web site designed by the researchers. The “self-directed” group was urged to maintain their weight loss but received no further intervention.
After 30 months, the personal contact group had regained an average of 8.8 pounds less than the self-directed group. The difference between the personal contact group and the interactive technology group was 3.3 pounds.
Overall, 71 percent of the study volunteers maintained at least some weight loss over 30 months.
“Change is possible. Truly, you can make a difference with simply reducing caloric intake and increasing energy expenditure,” said Machesky, who added that this study’s finding suggests that surrounding yourself with people who are supportive could also be helpful.
