One gram of uranium has 20 billion calories – radiation aside, would that many calories at once kill you?

Question

One gram of uranium has 20 billion calories – radiation aside, would that many calories at once kill you?

In:

Answer 1

If you put radiation aside, a gram of uranium won’t have many calories. And none of those calories are likely to be bioavailable, so your body wouldn’t absorb them anyway. The’d just be excreted.

Assuming that the radiation didn’t matter at all, of course.
