On April 9, Shindong and Don Spike guested on JTBC's 'Please Take Care of My Refrigerator'. 

During the show, Shindong revealed, "I went on a diet for our comeback. Two months ago, I weighed 116kg (256 lbs) but now I'm 93kg (205 lbs)." 

The idol shared how he lost 23kg (around 50 lbs), and said, "I really studied hard for my diet. I read a lot of books and also watched documentaries. I went on a 'free regulated diet'. The main point is to not fight against hunger. You sufficiently eat the food that doesn't make you gain fat."

The foods Shindong ate during his diet were soy milk, tuna, jelly, basil candy, zero cola, calamondin, and canned goods.

Shindong added, "You can't eat that much even if you're allowed to eat without a limit. You always have to have in mind that you're on a diet."
