S1, E6: Members go on a summer vacation to a water park! But for some reason, Diet youngest members, Ju Yeon and Moon Chi, are screaming at the top of their lungs? Barbeque can't be left out on summer vacations. Eat "this" before eating meat if you're on a diet? The girls can eat meat only if Shin Young gives them the go. From barbeque skewers to the special dessert that Shin Young made for them, the Diet team enjoys a perfect meal. Of course, having a good talk can't be left out.
