The 'Mom' actress is a big "foodie" and her husband - who shed 65lbs for his role in 'Guardians of the Galaxy' - admits his wife's excellent cooking is one of the reasons why he used to be overweight.

Speaking of Anna ordering for him, he said: "I love it. It takes the pressure off."

He added: "Back when I was fat, it was truly the result of her being an exceptional cook and loving to feed me. It works for us."

Chris - who has two-year-old son Jack with Anna - understands he now needs to stay in shape for the sake of his work.

He said: "It has translated to a lot of success in my career, so I understand it is part of my job now."

And though he admits it "sucks" sometimes to have to visit the gym regularly, the 'Jurassic World' star is as passionate about fitness as everything else he turns his hand to.

He told Britain's Glamour magazine: "I've grown to really like staying in shape. No matter what I do, I get really passionate about it. If that means eating fattening foods and drinking beer, then goddamn I will drink more beer and eat more than anyone else.

"I love to indulge, so I've given a lot of that up and traded it for time spent running or biking or swimming or in the gym, it's the same thing, I just do it to the best of my abilities.

"It sucks sometimes - I woke up at 5.30 this morning and did an hour and a half in the gym, and I didn't do it for the fun of it, I did it because it's required of me to be my best."
