Let’s get one thing straight: Zac Efron never actually had a "dad bod."
In 2020, when the Netflix travel docuseries Down to Earth hit screens, the internet collectively lost its mind. Twitter was a mess of thirsty memes and "he's just like us" celebrations. People looked at a bearded, slightly bulkier Efron—who was actually just at a healthy body fat percentage—and decided he had finally let it all go.
He hadn't.
What we were actually seeing was a man who had survived a "fitness prison" and was finally eating a piece of pasta without having a panic attack. The term "Zac Efron dad bod" became a viral sensation, but it also highlighted a pretty messed-up reality about how we view men’s bodies. If a guy with massive biceps and a visible four-pack is considered "out of shape," what does that say about the rest of us?
The Baywatch Nightmare Nobody Saw
To understand why the world thought Zac had a dad bod, you have to look back at the Baywatch era of 2017. He looked like he was carved out of marble by a sculptor who was also a little bit angry. It was insane.
Honestly, it wasn't even human. Efron has since admitted that the look was a complete lie. He was taking powerful diuretics (specifically Lasix) to shed every last drop of "water weight" so his skin would shrink-wrap over his muscles. He wasn't just working out; he was training at 4:00 AM after finishing shoots at midnight.
He was miserable.
"I don't ever want to be in that good of shape again," he told Sean Evans on Hot Ones. He wasn't kidding. The process led to severe insomnia and a "pretty bad depression" that lasted for a long time. When you see him in Down to Earth, you aren't seeing a guy who stopped caring. You’re seeing a guy who decided that being able to sleep and feel joy was more important than having 5% body fat.
Why the Internet Called it a Dad Bod
The "dad bod" label usually describes someone who hits the gym but also loves a Saturday night pizza and a six-pack of beer. Think Jason Segel or Chris Pratt before he got Marvel-sized.
So, why did the label stick to Efron?
- The Beard Factor: He grew a thick, "lumberjack" beard that instantly aged him from "Disney heartthrob" to "outdoorsy father figure."
- The "Bulk": Compared to the paper-thin skin of Baywatch, Efron had an extra 2% to 3% of body fat. In Hollywood terms, that’s practically a transformation into Santa Claus.
- The Vibe: He was genuinely happy. There’s a scene where he eats carbs with locals and looks like he might actually cry from relief.
The New York Post even ran a headline about his "shocking" transformation. It was a weird moment for culture. People were "shaming" him for looking like a peak-performance athlete instead of a dehydrated action figure.
The Iron Claw and the Return of the Unit
If people thought the dad bod was the end of his fitness journey, they were dead wrong. By 2023, for his role as Kevin Von Erich in The Iron Claw, Efron didn't just get fit—he became an absolute unit.
This wasn't the "shredded" look of Baywatch. This was a pro-wrestler bulk. He put on serious mass, looking more like an 80s action star than a lifeguard. It was another extreme, proving that his "dad bod" phase was really just a recovery period. He’s a chameleon. He moves between shapes based on what the job requires, but the mental toll remains a constant conversation for him.
He’s been very open about the fact that these transformations "burn him out." It takes months to "re-center" after living like a professional athlete for half a year.
The Problem With the Label
Calling a fit man "out of shape" creates a dangerous standard. When we label a healthy, muscular physique as a "dad bod," we basically tell every average guy that their body isn't even on the map.
It’s unrealistic.
Efron himself has spent the last few years trying to dismantle the idea that his movie bodies are something people should aim for. He’s literally told fans that the Baywatch look is "fake" and "CGI-ed" because of the dehydration involved.
What We Can Actually Learn From Zac
If you're looking at your own "dad bod" in the mirror, there are some genuine takeaways from Efron’s journey that don't involve 3:00 AM deadlifts.
1. Recovery is as important as the work.
Efron shifted his focus from "mirror muscles" to longevity. He now swears by foam rolling, yoga, and ice baths. It’s about how the body functions, not just how it looks under studio lights.

2. Carbs aren't the enemy.
Watching a millionaire movie star get emotional over a bowl of pasta is a great reminder that extreme restriction isn't sustainable. It messes with your brain.
3. Mental health dictates physical health.
The depression Efron faced during his peak "fitness" years shows that a six-pack won't fix your head. In fact, sometimes it’s the cause of the problem.
4. The "Ideal" is a moving target.
One year he’s Troy Bolton, the next he’s a shredded lifeguard, then he’s a "dad," then he’s a 220-pound wrestler. Your body is going to change. That’s just part of being alive.
The whole "dad bod" saga was basically a giant social experiment in how much pressure we put on celebrities—and ourselves—to maintain the impossible. Efron is still jacked. He’s still a movie star. But he’s also a human being who deserves to eat a slice of bread without it being a national news story.
Actionable Next Steps for Your Own Routine
- Audit your "Inspo": If the people you follow on Instagram are dehydrated and using diuretics to look "ripped," unfollow them. It’s a false baseline.
- Focus on Mobility: Instead of just lifting heavy, incorporate some of Efron’s current staples—stretching and foam rolling. It prevents injury and helps you feel "alive" rather than "bogged down."
- Prioritize Sleep: Efron’s biggest regret was the 4-hour sleep cycles. If you aren't sleeping 7-8 hours, your gym gains are going to be overshadowed by mental burnout anyway.
- Adopt the Ice Bath: If you want a piece of his current "wellness" routine, try cold exposure. It’s less about the muscles and more about the "mental win" of doing something uncomfortable first thing in the morning.
