YouTuber Nikocado Avocado just served his fans the ultimate surprise.

The 32-year-old, known for his “Mukbang” videos that show him eating giant food portions, released a clip Sept. 6 revealing a slimmer appearance from his previous posting, shared in February, that he attributed to a loss of 250 pounds.

But while the time that elapsed in between his videos suggested this feat was accomplished in seven months, the YouTuber—whose real name is Nicholas Perry—signaled that he dropped the weight over the course of a longer period of time, revealing that during the past two years, he had shared solely older footage of himself.

“Two steps ahead, I am always two steps ahead,” he said in his latest YouTube post, which shows him wearing a giant panda mask. “This has been the greatest social experiment of my entire life.”

He continued, “It’s alluring, it’s compelling, it’s gripping to observe all these unwell, disoriented beings roam the internet in search of stories, ideas, rivalries where they feel encouraged and engaged. Where they involve themselves with the stories and become a product of influence, thirsty for distraction from time unspent spoiling their minds, yet stimulating them at the same time.”
