Why Does Kate Beckinsale Pack Butter in Her Suitcase?!

With her uber-fit frame, Kate Beckinsale is hardly the kind of person we'd associate with butter. (More like: green juice, the Keto diet — you get the picture.) But, the actress cops to being so addicted to Kerrygold butter, she actually packs it in her luggage when she's on the road. It's not to spread on bread, though...

As it turns out, the English star starts her mornings with Bulletproof coffee. Quick refresher: That's the kind of Joe that's made with oil and butter, and its fans say it enhances both energy and brain function. 

Speaking to People, Beckinsale said: "When I did Pearl Harbor they had me on a very strict low-fat diet. I remember my mum coming and visiting me and going, ‘You look so old.’ I was 24 and I had lines on my face because I didn’t have enough fat. And so now, I remember very early on meeting a great nutritionist and they said, ‘One day everyone is going to say don’t eat low-fat margarine or they are going to say eat butter or eat olive oil.’ And it did take quite a long time, but I really noticed if I can eat coconut oil and butter and things like that, obviously in moderation, it makes almost an immediate effect on your skin. I don’t think it is a myth. I think you can see the difference in a week or two.”

And Beckinsale is committed to the stuff — no matter where she is in the world. "If I’m going from one city to another I’ll put some in my suitcase to make sure I have it. I’m the crazy person traveling with butter,” she said. 

Crazy? Or genius?
