**Wayne Knight’s Remarkable 100-Pound Weight Loss Nearly 30 Years After *Seinfeld***
*Published: September 26, 2025, 3:27 p.m. ET*
Hello, Newman! Wayne Knight, best known for his iconic role as Jerry’s postal nemesis Newman on the groundbreaking sitcom *Seinfeld*, has undergone a striking transformation. Nearly three decades after the show ended, the actor was recently spotted in Los Angeles looking almost unrecognizable following an impressive 100-pound weight loss.
At 70 years old, Knight was seen arriving for a workout in L.A., dressed casually in a dark gray polo, black athletic sweats, and comfortable sneakers. Despite his noticeable limp and grimace after the session, his new, leaner appearance is a clear testament to his commitment to a healthier lifestyle.
### From Newman to a Health Transformation
Wayne Knight is also known for other memorable roles, such as Dennis Nedry in the 1993 classic *Jurassic Park*, as well as appearances in *Space Jam* and *Basic Instinct*. At his heaviest, the 5-foot-7 actor weighed over 300 pounds. His health took a serious turn when a cardiologist warned him he was at high risk for diabetes, heart disease, and strokes. This shocking wake-up call prompted Knight to make drastic lifestyle changes.
A source shared with RadarOnline, “That was the ultimate wake-up call.”
### The Turning Point
Knight has joked about his lifelong struggle with overeating, once quipping, “I used to get a tan from the light in the refrigerator.” However, it was during the filming of *Seinfeld* that he first realized his health was in jeopardy. Recalling a scene in which he was running through a cornfield being fired upon, Knight said, “At some point in the middle of shooting, I couldn’t catch my breath.”
“It scared me literally to life,” Knight admitted. Taking his cardiologist’s advice seriously, he sought help from fitness professional Marc Vahanian and began a dedicated fitness regimen.
### A New Lifestyle
Now, Knight commits to at least two 20-minute workouts per week at a gym in Los Angeles and follows a gourmet delivery service diet, maintaining a daily caloric intake of about 1,500 calories. Today, he weighs under 200 pounds.
Ironically, his weight loss has also impacted his acting career. Knight has shared that losing so much weight affected the types of roles offered to him. “It takes time for people to accept you as you are, and they find out whether or not you can still do things without being fat,” he explained. Yet, he is happy with the tradeoff, stating, “You just have to accept the fact that you can’t sell something that you’re not.”
### The Secret to Success
Wayne Knight echoed these sentiments in a 2004 interview, revealing people often react with surprise at his slimmer appearance. At his peak weight of 327 pounds during *Jurassic Park*, Knight was frequently typecast as “the fat guy.”
Back then, he shared with CBS News, “We’ve got my cardiologist. We have my trainer. We have my psychiatrist. We have my support group.”
More than the weight loss itself, Knight emphasizes the importance of his improved health. “I was eating for reasons that have nothing to do with hunger,” he reflected. “I was eating to numb myself, and when I began to have to look at the fact that I was eating as an addiction and treat it as such, that’s when I turned a corner.”
Wayne Knight’s journey is an inspiring example of how recognizing and addressing health issues head-on can lead to profound life changes—and a new lease on life.
