If you've noticed Jason Sudeikis is looking a little fitter lately and were wondering what his secret was, bad news: It's not a plan that anyone other than Jason Sudeikis can follow. According to the actor in a new interview with ELLE magazine, his recent weight loss is all attributed to his fiancée, Olivia Wilde. More specifically, sex with Olivia Wilde.

ELLE: Speaking of which, you appear to have lost weight. Is that her influence?

JS: A lot of it comes from tiny things, like not eating barbecue sauce with my pizza at two in the morning. I think it’s all a manifestation of being happy and wanting to treat myself well. The truth is, I’m not getting up an hour earlier and walking on a treadmill. I have the greatest workout partner in the world. And you don’t need a gym membership for that kind of workout.

Do you hate him just a little yet? No? How about now:

ELLE: Nice. She memorably said you two have “sex like Kenyan marathon runners.” Was that an apt description?

JS: I would say it’s accurate.

Yes, that is a real quote Olivia Wilde said last year. Jason Sudeikis lost weight because of all the Kenyan marathon runner sex he's having with Olivia Wilde, and we're all still paying obscene amounts of money for gym memberships. Anyone who tells you life is fair sometimes IS LYING.
