A young Chinese doctor has gone viral for his rapid weight loss, shedding 25 kilograms (55 pounds) in just 42 days and then entering and winning a professional bodybuilding contest.

At the end of 2024, Wu Tian Gen, a 31-year-old surgeon at Hubei’s Zhongnan Hospital of Wuhan University, weighed 97.5 kg (215 lbs), the heaviest he had ever been, but by the end of January 2025, the 1.82m tall doctor had shed over 42 kilograms and was in such an amazing physical condition that he won a bodybuilding competition. How did he do it? Well, he didn’t share every detail, but it was a combination of personal ambition, physical training, and a carefully thought-out diet. Even so, losing so much weight in 42 days is nothing short of impressive.
