Mindblowing Question

Hey everyone! Prepare for your mind to be melted. There isn't really a complete 'answer' to the first one, at least to my knowledge, and it seems pretty ridiculous, but bear with me:
If you ate yourself, would you disappear completely or be twice as big?
Let me know if you guys want to see my personal answer to that question, and I'll PM you so as not to spoil it for everyone else There will be more brain teasers later, as I stumble across them on the interweb.

Neither technically work, but that reminds me of the poem "Hungry Mungry" by Shel Silverstein.

You'd die partway through your eating of yourself, but I'm going to operate under the assumption that you somehow survive. You have eaten your stomach, so you just end up in pieces which add up to the same size you originally were.

That was what the same conclusion I reached, but I had different reasoning.

You only have a certain amount of matter in your body. Eating yourself would only redistribute it. If anything, you'd probably end up with slightly less of yourself.

...And now I'm really grossed out. Why did I decide to think about this topic again?
