Banana has been known to be one of fattening food Korean dieters avoid because of its high caloric content. The study was conducted to investigate the effects of daily consumption of bananas on weight, body fat, and other obesity indices. Thirty overweight college students were randomly assigned to one of three groups: three(A), six(B) or nine(C) bananas a day. The subjects consumed bananas before each meal under the supervision for 20 days and maintain usual dietary life. Nutrient intakes were calculated from weekly diet records. All the measurements were taken before and after the study. From the findings, all three groups lost weight (0.6 kg for A, 0.9 kg for B, 1.5 kg for C; p=0.000) and also body fat(0.3% for A, 0.6% for B, 1.4% for C). In terms of abdomen fat loss, the greatest loss was noticed in group C(−1.2%) rather than the other two groups(−0.3% for A and −0.6% for B). Muscle mass was also the highest in group C(2.2 kg). Similar tendency appeared in BMI, WHR and abdomen skinfold thickness. Interestingly, all parameters tended to be decreased linearly related to the number of bananas consumed. Overall calorie and nutrient intakes of group A and B were reduced significantly except for group C. In addition, dietary fiber intakes of group C had increased significantly compared to those before the study. In conclusion, the usual consumption of at least three bananas a day led weight and fat loss, obesity indices and also muscle mass gain. The mechanism bananas reduce weight and body fat needs to be elucidated further.
