While many celebrities keep their health and fitness secrets under wraps, Caitlin O’Connor is doing the opposite — she’s opening up about exactly how she stays camera-ready and confident alongside her boyfriend, actor Joe Manganiello.
From cutting-edge nutrition to grueling gym sessions, Caitlin’s lifestyle is anything but ordinary.
Fueling Her Body Based on Science, Not Fads
When it comes to food, Caitlin isn’t guessing.
She follows a meal plan curated by Precision Food Works, a company that creates customized menus based on individual blood work.
Yep — her nutrition is literally tailored to her DNA.
Speaking with Daily Mail, Caitlin explained, “I eat meals from Precision Food Works based on my blood work designed specifically for my health.”
According to the company, their tech-driven approach uses advanced algorithms and blood/urine analysis to determine the exact amounts of protein, carbs, and fats your body needs — no more, no less.
Joe Manganiello, her longtime partner, is also on board with the plan.
Caitlin said he loves that it’s built around each person’s genetic profile, calling it a totally personalized way of eating.
Hydration and Discipline Are Her Daily Staples
It’s not just about what she eats — Caitlin swears by proper hydration.
“I drink 2.5 liters of water a day, that is a must,” she shared.
And while her glamorous Instagram might make it look effortless, she works hard to keep her toned physique.
“I love to exercise and work out three to five times a week, or as often as I can while traveling,” she revealed.
Pilates, Weight Training… and Yes, Even Cardio
Caitlin keeps her workouts fresh and challenging.
She enjoys weekly Pilates at Alo Wellness Club and adds in as much weight training as possible. But she admits there’s one thing she’s not crazy about: cardio.
Still, she powers through, doing 45 minutes of inclined walking or stair climbing.
Her go-to gym partner? Joe, of course. The couple often trains together at Gold’s Gym in Venice, California
“He’s a great workout buddy,” she said.
More Than Just a Pretty Face on Instagram
Beyond bikini pics and fitness inspiration, Caitlin’s career is just as dynamic.
She’s currently a correspondent for E! News and has some notable acting credits too.
She portrayed Dyan Cannon on HBO’s Winning Time and made a memorable guest appearance on the series finale of Two and a Half Men.
A Love Story That Started in a Hot Tub
Joe Manganiello and Caitlin first crossed paths in a very Hollywood setting — a hot tub at an unofficial afterparty for Winning Time.
According to sources, they hit it off right away and were deep in conversation from the moment they met.
Just a few months after Joe’s split from Sofia Vergara, he and Caitlin were seen together.
By December 2023, they made their red carpet debut at the Children Of Armenia Fund gala in New York, where Joe, who is part Armenian, was being honored.
Joe and Sofia: Why It Didn’t Work Out
Joe’s marriage to Sofia Vergara ended in 2023 after nearly a decade together.
The pair had tied the knot back in 2015 when she was one of TV’s biggest stars and he was riding the wave of success from True Blood and Magic Mike.
Sofia later claimed their breakup was due to differing views on parenthood — she didn’t want to be an “older mom,” while Joe supposedly wanted children. But Joe pushed back on that narrative.
In an interview with Men’s Journal, he said they had tried to start a family early in the marriage and he never issued ultimatums.
“The divorce happened because two people grew apart, and sometimes that happens,” he explained.
He also rejected rumors that he was going through a midlife crisis or pressured Sofia to make life-altering decisions.
Sofia’s Romantic History Before Joe
Before marrying Joe, Sofia was previously married to her high school sweetheart Joe Gonzalez, and they share a son, Manolo, now in his 30s.
After that, she was in a long-term relationship with actor Nick Loeb, whom she was briefly engaged to before they split in 2014.
A Low-Key, No-Drama Relationship
Sources close to Joe and Caitlin say they’re an easygoing couple.
Caitlin has been described as grounded, not a big partier or heavy drinker, and refreshingly low-maintenance.
It seems their shared lifestyle and mutual respect are key to their relationship’s steady growth.
What’s Next for Caitlin and Joe?
With Caitlin thriving in both her personal and professional life, and Joe clearly happy in his post-divorce chapter, things seem to be moving in a positive direction for the pair.
Whether it’s on red carpets or in the gym, they’re showing that balance, self-awareness, and science-backed wellness can make a real difference — both physically and emotionally.
