Weight Loss Interventions

A recent article in The NEW ENGLAND JOURNAL of MEDICINE compares two weight-loss interventions on 425 obese people with at least one cardiovascular risk factor. The mean age was 54 years old. Outcomes were compared between each intervention group and a control group and between the two intervention groups. The trial lasted 24 months.

At the end of the 24 months the total loss was:

−0.8 kg in the control group, −4.6 kg in the group receiving remote support only (P<0.001 for the comparison with the control group), and −5.1 kg in the group receiving in-person support (P<0.001 for the comparison with the control group).

Of the people who lost 5% or more of their weight, 19% were in the control group, 38% received remote help only, and 41% were in the group receiving personal, face to face, support from their primary care providers.

I found it interesting that the people left to themselves – the control group did lose some weight, -.8kg) over the two years. But during those two years both those who had in person face to face support and those who had remote support via email or phone lost significant weight (38 and 41%).

Get yourself a partner and make yourselves accountable to each other.

About Vic

As a retired Commercial/Missionary pilot and administrator, I started taking SilverSneakers® classes in 2007. Although I had kept up minimal jogging and biking, I had little lean body mass and extra fat, so I started lifting weights and joined a Group Power barbell class. Later I was challenged to use free weights for heavier lifting and body weight exercises for flexibility and functional fitness. The SilverSneakers® Coordinator asked if I would train to teach the class. Little did I realize that it would take almost a year, four classes, a practical evaluation, plus an on-line 100 question test, to complete the certification. I am still impressed with the research and years of practical experience that has gone into the SilverSneakers® model.
