How does paula deen keep from being morbidly obese?

I mean Paula deen is a big women, yes, but the way she cooks she should be twice her current size. All that er, bacon, donuts, er, cheesecake, chocolate and er she uses in every episode is astounding. She once made a hamburger with donuts for buns. How does she keep from being to obese to get out of bed!?!?!
