On July 14, 2PM’s Nickhun shared a series of photos on social media with the caption: “Nothing better than home.” The images captured the singer enjoying time with his family in his hometown of Thailand.

However, what immediately caught fans’ attention was his noticeably toned physique. Posing shirtless, Nickhun showcased broad shoulders, defined muscles, and a lean frame, reminding fans of his appearance during 2PM’s peak years.

Nickhun’s transformation comes just weeks after fans noticed he had gained weight while appearing on 2PM’s self-produced content. At the time, the singer explained that he had visited his family earlier this year during a break from work. “I didn’t have many schedules at the beginning of the year, so I went home. I ended up eating too much and gained weight,” he admitted.

To quickly return to his desired physique, Nickhun reportedly followed an extreme three-day diet, eating just one egg per day a total of three eggs over three days. The dramatic transformation has since amazed fans, who praised his discipline while also expressing concern over the intensity of the diet.

Nickhun’s physical transformation comes as 2PM gears up for its highly anticipated full-group return. The group will hold its 2026 2PM Concert “THE RETURN” in INCHEON on August 8 and 9 at Inspire Arena in Incheon, marking one of the biggest reunions for the veteran K-pop group in recent years.

Fans are eagerly awaiting the performances, especially after seeing Nickhun’s return to his signature “beast idol” form ahead of the concerts.
