Weight Changes in Obese Men
Weight Loss Study Aim
To describe a combined behavioural treatment program for obese men, the
'Gustaf' study, and to evaluate treatment success by the means of weight
loss, drop-out analysis and changes in metabolic risk factors. Subjects
included 86 men, aged 43±9
y and BMI 37.7±4.4 kg/m2, from the waiting list of the outpatient
clinic and men directly approaching the Obesity Unit.
Weight Loss Study Method
Combined, behavioural modification treatment, by the means of group sessions,
for one hour every week over a two-year period.
Weight Loss Study Measurements
Weight loss and changes in risk factors after completion of one and two
year study and description of treatment success in the form of changes
in metabolic risk factors.
Weight Loss Study Results
The one-year dropout rate was 22 percent and the cumulative rate after
two years was 34 percent. Mean weight decreased significantly from start
(121 kg) to one year (114 kg) and to two years (115 kg) in completers.
Several metabolic risk factors (waist and hip circumferences, systolic
blood pressure, serum cholesterol and plasma insulin) remained significantly
decreased after two years of treatment. The complete metabolic syndrome
was diagnosed in five men at onset, but in no one after two years. There
was no difference in change of metabolic risk factors after one year between
the men who lost 8-12 percent of initial body weight and those who lost
more.
Weight Loss Study Conclusion
Sixty-six percent (57/86) of the obese men who started in the 'Gustaf'
program were still in the program after two years. In spite of the relatively
modest weight loss, the men maintained a large proportion of this weight
loss and also maintained their improved metabolic risk factor pattern.
