As a leader, you may not be able to control what you’re feeling, but awareness of the energy coursing through you and others can be a tremendous asset. When you are experiencing catabolic energy, for instance, you might count to 10 before responding to a perceived attack. In doing so, you might avoid a blowup or action that you’d later regret. When you are being overly optimistic (due to anabolic energy/endorphins), you might seek to cool down your enthusiasm instead of your anger. By asking for input or information about potential risks, you might avoid taking too great a risk.
There are, however, some foods where the caloric expenditure to process them is a little higher than the calories they provide the system. The clear example is water, especially ice-cold water. The body needs to warm it up before absorbing it, leading to a small caloric debt. Foods with very high water content, such as celery, also have this tiny catabolic effect. But the nutritional value of water and celery are not high enough to properly sustain an organism, so relying solely on these foods to lose weight can lead to serious health complications.
