Red Velvet say they're now experts on losing weight!

On the September 13th airing of 'Choi Hwa Jung's Power Time', the members talked about how they went on a diet for their comeback with "Russian Roulette". Joystated, "We have developed dieting methods over the years. In the past, we just starved ourselves to lose weight, but now we go on a diet by exercising. I didn't weigh myself, so I don't know how many kgs I lost exactly, but this time I lost weight easily."

Wendy also added, "In the past, we used to worry about not being able to eat, but after receiving so much love, we can now control ourselves from food. I think it's all thanks to our fans."
