Affleck's quick meal comes as sources close to the power couple say the Argo star, 50, has been trying his best to stay in shape with some help from the Selena actress, 53. "There are trainers at the house, there are chefs at the house and there is healthy food everywhere he turns," an insider spilled about his diet plan.
Per the source, Lopez "loves to indulge in burgers and fries, but at home, it’s a really healthy house," noting, "Lots of water. No soda. Yoga in the morning outside. A casual run if she’s free in the afternoon, and she’ll bring Ben with her."
"Ben used to only go outside to pick up his Dunkin’ deliveries and fast-food deliveries. Munchkins for days," the insider continued of his favorite coffee chain. "Now, he’s going outside to sit for a nice breakfast with Jennifer on the patio with avocado toast, granola and berries."

Although Affleck — who wed Lopez twice last year — "still loves his Dunkin coffee," the source spilled, "he’s the happiest he’s ever been, so he’ll tell anyone that that means he’s the healthiest he’s ever been, too."
"He really wants to take care of himself for Jennifer and the kids and be really present, and he does feel his best when he’s working out with a trainer and eating right," they added.
