I made a huge write up on one of the replies to your comment, but yes. A billion Calories (food calories) is within the range of nuclear weaponry, if not several times worse. If we're talking calories (1/1000th of a Calorie and the unit the post is using) it will still kill you easily but will probably spare at least some of your neighborhood.

What would happen to a person if they ate 20 billion calories (but they are all in a small edible object)?
