Abstract

Dietary supplement mainly made of herb and fiber was examined whether it could reduce body weight and fat, modify blood lipid concentrations and bowel habits in 30 collegians without intentional diet restriction or lifestyle change for 5 weeks. Free-living subjects were required to take diet pills 2 times daily 30 minutes before meals. Before the study began, 24 hr recall diet record and the questionnaires had been collected. Anthropometric measurements (height, weight, waist and hip circumferences, triceps and abdomen skinfold thickness, and body fat) were performed and blood samples were withdrawn before and after the study. Blood lipid fractions analyzed were total cholesterol (TC), triglyceride (TG), HDL-cholesterol and LDL-cholesterol. After the trial, body weight, body mass index, and percent ideal body weight of the subjects were reduced to mean of 0.5 kg, 0.2 and $0.9\%$, respectively (p<0.05). Percent body fat, triceps and abdomen skinfold thickness, and waist and hip circumferences were all reduced significantly except for $\%$ abdominal fat, but $\%$ body muscle mass increased from $36.5\%$ to $37.4\%$ (p=0.000). TC and TG were remarkably diminished (p<0.01) and LDL-cholesterol tended to decrease, but no change was observed in HDL-cholesterol. Bowel movements were also increased (p<0.01). In conclusion, this specific herb and fiber-rich dietary supplement reduced body weight and body fat indices, improved anthropometric indices, modified blood lipid fractions and bowel movement desirably. The study suggest that herb and fiber-rich dietary supplement might help control body weight, body fat loss and adult diseases positively.

본 연구는 생약제와 식이섬유가 주성분인 다이어트 제제가 체중, 체지방, 혈액지질분획 및 배변습관에 미치는 영향을 알아보기 위하여 대학생 자원자 30명을 대상으로 5주 동안 실시하였다. 다이어트 제제는 1일 2회 섭취케 하되 본인의 일상 식사 및 생활양식을 그대로 유지케 하였으며 실험전 설문지 조사를 통한 대상자의 일반환경요인 평가와 식이섭취 평가가 실시되었다. 실험기간 중에는 주 3회 식이일지 작성과 매주 체중을 측정토록 하였고 실험 개시 일과 종료일에는 혈액채취와 신체계측이 실시되었다. 실험대상자의 특성을 보면 중산층 이상으로 평균 나이 21세로 정상체중을 유지하였다. 운동은 절어도 30분간, 주 $1\~2$회 이상하였고 음주율은 매우 높았으나 흡연은 거의 하지 않았다. 식사는 적어도 2끼 이상 먹는 편이나 외식빈도가 많았고 식습관이 불량하였으며 배변횟수는 보통이었으나 변비경험은 비교적 많았다. 영양소 섭취량은 전반적으로 낮았으며 실험개시기에 비해 종료시에 식이섭취 및 영양소 섭취량이 낮은 경향을 보였다. 체중, 체질량지수, 표준체중백분율은 물론 체지방비율, 피부지방두께, 허리둘레, 엉덩이 둘레 및 WHR등은 실험개시시에 비해 종료시 감소하였으며(p<0.05),반면에 근육량의 비율은 유의하게 증가하였다(p<0.05). 한편 혈액 총 콜레스테롤과 중성지방은 유의하게 감소하였으나(p<0.05) HDL-콜레스테롤농도는 변화가 없었고 LDL-콜레스테롤농도는 실험개시시에 비해 종료시 감소하는 경향을 보였다. 혈압은 실험 전과 후에 변화하지 않았다. 배변횟수는 실험 개시기에 비해 종료시에 증가하였다(p<0.05).위의 결과를 종합해 볼 때 본 연구의 생약제와 섬유질로 제조한 다이어트 제제가 체중과 체지방 및 비만관련 신체지표를 유의하게 감소시켰으며, 혈액 중 일부 지방분획과 배변횟수도 바람직하게 변화하였다. 그러나 더욱 통제된 후속 연구가 이뤄져야 할 것으로 사료된다.
