Ben Affleck and Kevin Costner reportedly have different approaches to tackling Jennifer Lopez’s demands
Ben Affleck and Kevin Costner appear to have starkly different attitudes toward diet and fitness, with one reportedly embracing a strict regimen while the other indulges in long-missed favorites. According to In Touch, Yellowstone star Kevin Costner has been inspired by Jennifer Lopez’s dedication to health and fitness and is now committed to getting in peak shape.
A source revealed that Costner is following a “high-protein plan to go along with his training regime that his personal chef will be strictly following.” The actor, who is known for maintaining an active lifestyle, reportedly has a clear goal in mind.
“He wants to lose some weight and add 10 pounds of muscle in time for summer,” the insider shared. Meanwhile, Affleck—who recently split from Lopez after 21 months of marriage—has taken the opposite approach, reportedly embracing a diet of fast food and sweet treats now that he’s no longer with the fitness-focused superstar.
A source told RadarOnline that Affleck always had a love for indulgent foods but felt restricted while with Lopez. “Ben loves McDonald’s, Taco Bell, Jack in the Box, and Starbucks coffee drinks and treats,” the source revealed. The insider added that during his time with Lopez, Affleck “felt deprived of his favorite foods, snacks, and sodas.”
Now, with their relationship reportedly over, Affleck is making up for lost time. “Now that [Lopez] is finally gone, he can go to town and put his stomach through the kind of workout only he can appreciate,” the source quipped. Affleck and Lopez, who rekindled their romance two decades after their initial engagement, have long been seen as an unlikely pairing when it comes to lifestyle choices.
While Lopez has built a brand around clean eating and fitness, Affleck has often been spotted with fast food and iced coffee in hand. Costner’s reported fitness transformation and Affleck’s return to old habits highlight how different perspectives on health and wellness can shape relationships—and how personal priorities shift after a breakup. Whether Affleck’s approach is a short-lived indulgence or a long-term lifestyle choice remains to be seen.
