Coin Jackson reveals their diet regime

Recently, rookie group Coin Jackson had an interview with SPN where they revealed their diet regime. The new group stated, "4-5 months before our debut we were practicing hard and had a very strict diet." Breakfast consisted of half a bowl of brown rice along with some low-sodium side dishes. Lunch included banana's and three egg whites. Dinner consisted of one sweet potato; one egg white; walnuts, almonds, various other nuts; and milk. In addition to this diet, the members also practiced singing and dancing for 14 hours a day. The interviewer asked, "Can you endure a day on this kind of diet?" The members responded that they endured their hunger and rarely deviated from this diet. One time there was an incident where maknae Wooyoo went to the hospital. On the way back, she bought a walnut cake in an alley while the manager wasn't looking, but in the end she was caught. The other members were asked whether they secretly snacked in between meals, but unfortunately none of the members spoke up. Source: SPN via Nate
