Long Term Weight Loss Program Study
Weight Loss Study Background
Despite the well-documented success of behavioral techniques in producing
temporary weight loss, treatment is typically followed by weight regain.
The maintenance of treatment effects may therefore be the greatest challenge
in the long-term management of obesity, and continuous care may be necessary
to achieve it.
Weight Loss Study Aim
To describe the design and evaluate the effectiveness of the Trevose Behavior
Modification Program, a potentially widely replicable self-help weight
loss program offering continuous care.
Weight Loss Study Subjects
One hundred and forty-six women aged 44y with a body mass index (BMI,
kg/m2) of 33, and 25 men aged 49 with a BMI of 35 enrolled in the Trevose
program during 1992-1993.
Weight Loss Study Results
As long as they remained in treatment, almost all participants lost at
least 5 percent of their initial weight and at least 83 percent lost more
than 10 percent. Members completing 2 y of treatment lost an average of
19.3 percent of their initial body weight (17.9 kg); at 5 y the loss was
still 17.3 percent (15.7 kg). After leaving the program, subjects regained
weight but remained 4.7 percent (4.5 kg) below their pretreatment weight.
Weight Loss Study Conclusion
A low-cost program offering treatment of indefinite duration produced
large long-term weight losses and may be suitable for widespread replication.
