Effect of a Weight Loss Program on Body Composition and Metabolic Syndrome Markers in Obese Weight Cyclers
ABSTRACT: to evaluate the
effect of weight loss program on fat mass, visceral fat rating and metabolic
syndrome markers in obese subjects with weight cycling. Methods: this was an
8-week open trial. The subjects were recruited consecutively from Balai Kota
DKI Jaya. Subjects were classifed into two groups according to the fluctuation
of weight gain (weight cycling/WC and frst encounter obesity/FEO group). Both
groups were assigned to receive weight loss program consisted with following
goals: a 1000 kcal energy intake reduction and 45 minutes mild-to-moderate
intensity physical activity three times a week. Body composition (fat mass,
visceral fat rating), and metabolic syndrome markers (waist circumference and
triglyceride levels) were measured at baseline, week 4 and at the end of study.
Results: seventy two subjects completed the study (34 subjects in WC group and
38 subjects in FEO group). Following weight loss program, a decrease in fat
mass, visceral fat rating, and waist circumference was lower in WC group
compared with FEO group but it was not statistically signifcant (p>0.05).
Triglyceride levels were decreased in the FEO group while it was increased in
WC group. However the difference was not signifcant (p=0.055). Conclusion:
weight loss program may contribute to changes in body composition and metabolic
syndrome markers in obese subjects, which the response appears to be worse in
weight cyclers.
