Picture this: you’re Pete Alonso, the New York Mets’ slugging first baseman, nicknamed the “Polar Bear” for your hulking 6-foot-3, 245-pound frame. You’ve smashed 53 home runs in a single season, but 2024 left you feeling like your swing—and your body—needed a reset. That’s exactly where Pete Alonso’s weight loss story begins. After a disappointing 2024 season, where his batting average dipped to .240 and his OPS hit a career-low .760, Alonso showed up to spring training in 2025 noticeably leaner, down 10 pounds to a svelte 235 pounds. So, what sparked this transformation? And how did dropping a few pounds turn the Polar Bear into a lean, mean hitting machine?
“I was carrying a little extra,” Alonso admitted to Newsday in 2023, reflecting on his decision to slim down. “I wanted to feel lighter, move better.” That mindset carried into 2025, where Pete Alonso’s weight loss became a cornerstone of his remarkable comeback. Fans noticed the change immediately, with one tweeting, “He lost weight,” and another adding, “Looking skinny!” But this wasn’t just about aesthetics—it was about reclaiming his edge on the field. Let’s unpack how Alonso made it happen and why it’s resonating with fans everywhere.
From Burgers to Balance: Alonso’s Diet Revamp
Pete Alonso’s weight loss started with a hard look at his plate. Known for his love of hearty meals, Alonso had to rethink his eating habits to shed 10 pounds. “I’m not gonna lie, I love a good burger,” he told Men’s Health in 2020, but by 2023, he was swapping fast food for smarter choices. His approach wasn’t about starvation or trendy weight loss drugs—it was about sustainable changes that fueled his performance.
Alonso’s diet now focuses on lean proteins, vegetables, and complex carbs. Think grilled chicken, sweet potatoes, and piles of greens. “I’m eating to perform, not just to fill up,” he shared with Newsday. His daily menu looks something like this:
- Breakfast: Egg whites with spinach and a side of oatmeal for sustained energy.
- Lunch: Grilled salmon with quinoa and steamed broccoli.
- Dinner: Lean steak or turkey with roasted vegetables and a small portion of brown rice.
- Snacks: Protein shakes or almonds to keep hunger at bay.
This shift helped Alonso drop from 245 pounds to 235 pounds, giving him the agility to chase grounders and the stamina to power through long games. “You feel the difference when you’re lighter,” he told The Athletic. “It’s not just about the scale—it’s about how you move.” By prioritizing nutrition, Alonso set the stage for his 2025 resurgence, where he’s hitting a scorching .365 batting average through early games.
Training Like a Beast: Alonso’s Fitness Routine
If you think Pete Alonso’s weight loss was all about diet, think again. The man who casually deadlifts 500 pounds didn’t shy away from the gym to sculpt his leaner physique. His offseason routine in Tampa, Florida, was a mix of grit and strategy, designed to boost his power without sacrificing strength. “I ran two miles as fast as I could, four times a week,” Alonso told Newsday in 2023, a habit he carried into his 2025 prep. That cardio, paired with strength training, transformed him into a leaner version of the Polar Bear.
His workout plan included:
- Cardio: Sprint intervals and long-distance runs to burn fat and improve endurance.
- Strength Training: Heavy lifts like deadlifts and squats to maintain his power-hitting core, as seen in a viral video of him deadlifting 500 pounds on Facebook.
- Mobility Work: Yoga and stretching to enhance flexibility, crucial for his improved defense at first base.
“I worked really hard to be able to hold my good mechanics,” Alonso told MLB Network in 2025. “Being the best version of myself pitch-to-pitch allows me to see the ball longer.” This dedication paid off, with Alonso posting a .341/.463/.659 slash line and 9 home runs in April 2025, earning him the National League Player of the Month award. His leaner frame didn’t sap his power—it amplified it.
The Mental Edge: How Alonso’s Mindset Fueled His Transformation
Pete Alonso’s weight loss wasn’t just physical—it was a mental overhaul. After a tough 2024, where he admitted, “I haven’t done that,” referring to his lackluster performance, Alonso knew he needed to dig deep. “People just care about production,” he told SNY in 2024. “When the lights come on, you have to perform.” That pressure, combined with his looming free agency in 2025, lit a fire under him.
Alonso leaned on a personal prep team, including analysts from his agent Scott Boras and his Tampa-based workout group, Diesel Optimization. “I’m just trying to look at everything I possibly can in-depth,” he told The Athletic. This analytical approach, paired with his physical transformation, turned him into a more disciplined hitter. “Knowledge is power,” he said, a mantra that guided his 10-pound weight loss and his stellar .365 batting average in 2025.
His teammates noticed the change. “He’s done his homework well before we’ve pumped out any information,” Mets co-hitting coach Jeremy Barnes told The Athletic. Brandon Nimmo added, “He’s invested in himself, and it’s paying off.” That mental shift—embracing preparation and resilience—made Alonso’s transformation more than skin-deep.

Pete Alonso’s weight loss resonates because it’s not just about dropping 10 pounds—it’s about bouncing back from a slump and proving the doubters wrong.

But Alonso silenced the skeptics with 17 home runs and 61 RBIs by June 2025, showing that less weight meant more impact.
His journey mirrors the struggles we all face—whether it’s shedding a few pounds or overcoming a career setback. “I feel I am in a really good spot,” Alonso told MLB Network. “Not just results-wise, but my mechanics are nice, efficient, and repeatable.” That confidence, born from hard work and a leaner physique, is what makes his story so inspiring.
