One such view is that rice has higher content of starch which easily leads to weight gain. According to the Nutrition and Health Survey in Taiwan from 2005 to 2008 (NAHSIT 2005-2008), there was an increase in prevalence of obesity in both men and women while there was a decrease in frequency of rice intake. The purpose of the study was to investigate the effect of rice intake on obese adults. There were 60 subjects (with BMI≧30) who had rice intake frequency≧8 times on weekly basis who were assigned to two groups, 30 subjects in each experimental and control group. All subjects took part in a 12-week weight reduction program. The program included exercise, psychological and nutritional education. The nutritional education of experimental (treatment) group component emphasized the principle related to rice consumption in weight reduction. Measurements were taken at week o and 12, including hematology laboratory evaluations, and anthropometry (e.g., height, weight), 24-hour dietary recall, short-form 36 health survey, and the brief version of the World Health Organization Quality of Life. After the 12 weeks treatment period, experimental (treatment) group’s subjects who had rice intake frequency ≧ 9 times higher than control group’s. And subjects. the subject’s intake of energy and protein and subject’s body weight, body fat mass, BMI, mineral, fat-free mass, muscle mass, BMR, total energy expenditure, blood pressure, abdominal [obesity], waistline, hips, visceral fat area, visceral fat weight, subcutaneous fat weight, left (right) arm fat, left (right) leg fat, trunk fat, left (right) leg [lean], GOT, and GPT all showed significant decrease in both groups. The physical fitness was enhanced which included step and fitness exercise in both groups. Besides, the loss of body weight, BMI, protein, fat free mass, muscle mass, BMR, total energy expenditure, [abdominal obesity], WBC, hemoglobin, GOT, GPT and TG in treatment group were significantly different from those of control group in 12 weeks. The total rate of metabolic syndromes for the treatment group improved 30% compared with the control group’s 13.4%. Moreover, general health and vitality quality of life showed significant difference after intervention in both groups. Mental and physical domain of the WHOQOL-BREF significantly increased in treatment groups. There was no significant difference in quality of life between experimental group and control group. Therefore, it would increase the effectiveness on weight loss and related indicators that giving moderate rice diet combined with exercise to those overweight and obese individuals. This study showed that low-energy diet with rice intake, in combination with exercise, was helpful for body weight improvement in overweight and obese individuals.
