Jezebelle and I probably go through a few lbs of butter a week easily. Except we make exceptional food, whereas you don`t have a clue what to do with it. So yes, it is possible to eat a ton of butter and remain extremely lean.
I am the leanest I have ever been in my life at 161 lbs. I wish it were warmer than 50 degrees so I would have reason enough to not wear a shirt and take a picture.
