Background/Aims: Overweight and obesity causes non-communicable disease and affects lower quality of life. Currently, Drinks with high protein is alternative choice. There are less Thai studies on the clinical effects of whey protein drinks. The aim of this study was to determine the effect of whey protein beverages consumption on anthropometric, defecation and quality of life
changes in overweight and obese volunteers.
Methods: Parallelcomparison study in eighty adults with overweight and obese. Subjects were equally divided into four groups of treatment: WPS-free with no exercise, WPS-free with exercise, WPS with no exercise or WPS with exercise for 12 weeks. Both WPS groups consumed 29 g whey protein dissolved in 300 ml water twice a day, 30 minutes before breakfast and dinner. Two exercise groups increased their
exercise 30 minutes/day, 5 days per week. Defecation was assessed using the Bristol Stool Form Scale-7. Quality of life assessed by questionnaire WHOQOL-BREF-THAI-26.
Results: The WPS group had no significant change in body weight or muscle mass compares with the WPS-free group but the WPS with exercise exhibited significantly lower%fat and fat mass at 12 weeks (p < 0.05).
Fecal appearance and quality of life were analyzed by Chi-square tests (SPSS software version 18; SPSS Inc., Chicago, IL, USA).
Conclusion: Whey protein beverages intake increased an average frequency of defecation and was correlated with quality of life in better physical health.
