Nine Muses' Sera recently caught the attention of fans and netizens for her slimmer physique with the group's "Figaro" comeback. As it turned out, she was revealed to have undergone a drastic image change with a 20 kg weight loss since her trainee days. A representative of Star Empire explained, "Sera said that she weighed over 70 kg when she first began training three years ago due to stress. She's been dieting ever since then and lost over 20 kg. She lost about 6 to 7 kg during Nine Muses' hiatus alone." So what's the secret to her diet? A lot of exercise and food control, says Sera. She revealed that she drank a powder drink of mixed grains the minute she got up in order to curb the tendency to binge on an empty stomach, and did aerobic exercises and weight training at the gym for an hour. She also made sure to drink protein shakes for her weight training sessions. Sera stressed the importance of snacking healthily like drinking a cup of milk because it's easier to binge when hungry.

She continued, "After I began exercising, I found myself having more strength during rehearsals and my body just began to feel lighter overall. I'm currently 170 cm tall and weigh in at 50 kg, but I'll continue dieting to manage my body." Star Empire added, "I think she felt a strong need to show a healthy body image even if it took some time. She's still consistently managing her weight by snacking on health food products like sweet potatoes. She'll continue to work towards improving her image so please look forward to it."
