Dylan Efron is opening up about an unexpected physical transformation from his time on the dance floor.
The reality star recently revealed he gained nearly 20 pounds during his stint on Dancing with the Stars season 34.
What makes his journey particularly fascinating is how his body composition shifted throughout the competition—initially losing weight before ultimately building significant muscle mass.
His candid breakdown of the changes offers insight into how intense training affects body composition differently than many expect.

The Weight Fluctuation Journey
On December 2, Efron shared a transparent update with fans via Instagram Stories, stepping on a scale that read 189 pounds. The 33-year-old Traitors winner didn’t hold back in discussing his physical transformation during the competition.
Probably TMI but I’m fascinated with this stuff. I weighed around 175-178 lbs. (80kg-ish) at the start of DWTS.
But his journey wasn’t a straightforward path to gaining muscle.
Early in the competition, Efron actually experienced weight loss despite the rigorous training schedule. By week three, he had dropped to 170 pounds—a development that required costume adjustments.
By week 3, I went down to 170, they had to take in my waist on my pants … a lot of cardio and wasn’t eating enough.
The Turning Point: Nutrition Changes
Recognizing that his body needed more fuel for the demanding choreography and rehearsal schedule, Efron made strategic dietary adjustments. The change in approach yielded dramatic results.
By the end of the show, my pant size was back to normal and I felt stronger. I gained about 15-20 Ibs. during the season, biggest thing I changed was eating more protein … protein shake every night and just more meat. But I feel so much stronger than before.
This nutritional shift highlights a critical aspect of performance training that many overlook: adequate caloric intake, particularly protein, becomes essential when activity levels spike dramatically.
Efron’s experience demonstrates how cardiovascular exercise alone—without proper nutrition—can lead to muscle loss rather than the strength gains most people associate with intensive training programs.
Competition Results and Physical Transformation
Efron’s dedication carried him to the season 34 finale, where he placed fourth among a competitive field. The final five contestants included Robert Irwin (who ultimately won the Len Goodman Mirrorball Trophy), Alix Earle, Jordan Chiles, and Elaine Hendrix.
While he didn’t take home the trophy, his physical transformation became its own victory. The nearly 20-pound gain represented quality muscle mass rather than simply added weight—a distinction he emphasized by noting his increased strength levels.
The Science Behind His Transformation
Efron’s experience illustrates several important principles about body composition and athletic training:
- Initial weight loss often occurs when exercise dramatically increases without corresponding nutritional adjustments
- Protein timing matters—his nightly protein shakes supported muscle recovery during sleep
- Muscle weighs more than fat, explaining why his pants fit normally despite the scale showing higher numbers
- Cardiovascular work combined with resistance training (dancing involves both) builds functional strength when properly fueled
His candid documentation of the process provides a realistic picture of how bodies respond to intense training—challenging common assumptions about weight loss being the primary goal of fitness endeavors.
Public Reaction and Family Fame
Fans have consistently praised Efron’s physique, with his social media posts regularly generating enthusiastic responses. This summer, he and older brother Zac Efron, 38, went viral with a shirtless golfing video that broke the internet.
The clip captioned “Sticks” showcased both brothers displaying impressive abs and physiques while playing golf. Comments flooded in from impressed followers.
One fan wrote, “And suddenly, I’m interested in golf?” Another commented, “Never thought I’d be jealous of a golf course but here we are.”
The Efron brothers have built a reputation for generating buzz with their fitness content. A September 2023 shirtless boat photo similarly went viral, cementing their status as social media fitness inspirations.
Key Takeaways for Fitness Enthusiasts
Dylan Efron’s Dancing with the Stars journey offers several practical lessons:
- Monitor your nutrition when dramatically increasing activity levels—undereating can sabotage results
- Protein intake becomes crucial during intensive training periods for muscle preservation and growth
- Scale weight doesn’t tell the complete story—body composition and strength matter more than numbers alone
- Strategic timing of nutrition (like nighttime protein shakes) can optimize recovery
- Initial weight loss doesn’t always indicate progress—sometimes it signals inadequate fueling
His transparent sharing of both struggles and solutions provides a roadmap for others facing similar challenges with high-intensity training programs.
The reality star’s willingness to discuss details many consider “TMI” actually serves an important purpose: demystifying the realities of physical transformation and highlighting that impressive results require strategic nutritional support, not just hard work in the gym—or on the dance floor.
