Great question. Off the top of my head the answer is no and yes a very
little. No there is not more energy to run your body in hot food. The
Calories in food do not go up when you heat up food. However, cold
food like ice cream does reduce your body temperature a little
requiring your body to use more chemical energy than it would have to
keep your body temperature up. This is where it is important to
remember that Calories for food are big C calories which are really
kilocalories. Eating cold food might use up a couple of small c
calories, several order of magnitude less than the the chemical energy
you are taking in. Ice cream is still a very high net calorie food,
celery is very low in net calories. Ice cream is more tasty than
celery.
