On the September 3rd broadcast of 'Incarnation', Sojung shared, "The reason I started my diet was because I met my members for the first time and they were all so pretty. But I don't have a pretty face. Only my voice is like that. [When I featured on 'Voice Korea'], I was 49 kg (~108 lbs.) but I lost 12 kg (~26 lbs.). Honestly, 49 kg is a normal weight but when I saw myself on TV, I received a big shock. I thought to myself that even with this figure, I come out this big on TV. Nothing fits me right now. I am a size 33." RiSe shared, "Whenever we shoot a pictorial, they slim down our figures through editing. But for Sojung, they have to widen her figure."
Sojung shared, "I don't have the thought of wanting to eat. I hated that I wanted to eat something so I didn't eat anything. I didn't eat anything and I just worked out. I just didn't eat. I used to drink only water all day. For 2-3 days, I ate only 5 cherry tomatoes. I just hated myself when I wanted to eat. When I get hungry, my stomach starts growling. But I would tell my stomach that I wasn't hungry. I would tell my stomach, 'I'm not hungry so why are you growling?' Now that I look back on it, I wonder why I did all that."
"When I first started my diet, I work out and didn't eat. I would feel dizzy and my hand would shake. I was washing myself in the shower when I felt like my body was breaking apart. I was wiping my body with a towel but it hurt so much..."
"This is a sensitive topic but when you start a diet, women experience something once-a-month. But I didn't have my period for close to a year. At first, I thought it was comfortable. But since I didn't have it for close to a year, I started to get worried. So I went to the hospital and the doctors told me that my physical condition became like the body of a 5th grade student in elementary school. They told me that my hormone levels dropped to the floor. I asked them what that means and they told me that my hormones are on the level of a woman who is going through menopause. I asked them what should I do? They told me that if I don't increase my body fat by 5 kg, I might have to live like that forever. Right now, I only have 5 kg (~11 lbs.) of body fat throughout my whole body. When I heard that, I realized that this wasn't right."
She assured fans, "I'm almost fully recovered now and I'm above 40 kg (~88 lbs.)", leading the MCs and guests to advise her to gain more weight as they're concerned for her health.
