'Eden, Descendants of Instinct' cast member Kim Ju Yeon gained 13kg to win the bodybuilding reality show, 'Battle Gram'. 

On August 26th, Wavve's original reality show 'Battle Gram' premiered. 'Battle Gram' is a bodybuilding reality show featuring 8 female and male contestants doing various missions to become the top bodybuilder. 

Their first mission was to gain weight for 3 weeks. At first, the contestants were hesitant but they became eager after they were informed they will earn prize money depending on their weight gain. 

One of the contestants, Kim Ju Yeon, garnered attention after gaining 13 kg to win the mission.   

Prior to the broadcast, she shared her weight gain tips on her Instagram such as "Do not work out (the most important tip)", "Reduce the time you're not eating. Desserts after the meal is a must.", and "Maximize your calorie intake by avoiding seafood and lean meat. Pair with drinks when you're eating."
