What do you mean calories have heat?

100 calories (medium apple or 2 regular Oreo cookies) is enough to boil an entire quart of water.

So how many quarts of water would you be able to boil in a day? (Hint: How many calories do we need a day?)

20-30 quarts of water

So why don’t calories make our blood boil?

Digestion and metabolism tap off energy in small amounts to power the body and some of the heat is used to actually keep us warm.

What is caloric intake?

Caloric intake = amount of food/calories we eat

What is caloric expenditure?

Caloric expenditure = amount of calories we use
