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.
