I know that each of you is waiting impatiently for me to reveal what I actually eat that made me lose 50 lbs.
Well here is one thing I eat most mornings.
Yes, really. Natto tastes fine, like what I remember pork 'n beans used to taste like when I ate that. But the slimy look leaves something to be desired.
One reason I eat it is that it has more vitamin K-2 than any other food in the world. There are a few vitamins that are in short supply in our diet. K-2 is one of them. For a more in depth discussion of this click here.
If you eat fermented cheese like blue cheese, liver, pasture fed butter and milk, or have good gut bacteria that live on soluble fiber, you might be ok—might. But if you don't, you should supplement. 
This is not the K-2 you are looking for, move on. (Remember that K-1 is not the same vitamin!)
K-2 is crucial in calcium allocation. Even if you have enough calcium, without this vitamin, along with vitamin D, the calcium is not laid down in the bones as well. Even worse, the calcium might be put in places you do not want it, like your heart.
So either crack open the styrofoam Natto container, eat a lot of blue cheese, or get some supplementation.
