Ok, a calorie is how much energy it takes to raise the temperature of water by 1 degree. So you can test how many calories something has by burning it and seeing how much it changes the temperature of water. A whole new meaning to burning calories.

Energy in the body is stored by making bonds and released by breaking them. So when we have a lot of high energy foods we spend some of that energy in making high energy bonds, so that we can break them later when we don’t have so much energy around.
