The Effects of Jeju Steaming Onion(Oniro) on Reducing Body Fat of Overweight or Obesity Subjects

A randomized, double‐blind, placebo‐controlled clinical trial was conducted to verify the effects of jeju steam onion. Fifty‐six healthy male and female subjects aged 20‐65 years with normal body weight [25.0 kg/㎡ ≤ body mass index (BMI) < 30.0 kg/㎡] were recruited. The basic framework of the present study was based on a previous study. A 12‐week (at each visit; screening, 6‐week, 12‐week), placebo‐controlled, randomized study was conducted with overweight subjects (25.0 kg/㎡ ≤ BMI < 30 kg/㎡). Subjects participants were divided into two group: either Jeju steaming onion or matching placebo (the baked barley powder). Randomization was achieved by computer generated block randomization (placebo : test = 1 : 1).
