Energy is like money; once spent, it's gone. However, it is possible to make an investment, as opposed to an expenditure, that yields a return.

Without an adequate supply of micronutrients, not only are we less likely to sleep deeply, recover briskly from exercise, ward off sickness, and fully exploit our brainpower, we get hungry. And we stay hungry.

What do we actually seek from food? It's not calories, nor is it volume or mass. It is, in fact, nutrition: micronutrients, which include vitamins, minerals, antioxidants, and phytochemicals. These are components by which food can be assessed a value, and therefore, a decision can be objectively made as to whether it's worth eating.

Since a calorie is a measure of food energy, you may understandably assume that the more calories you consume, the more energy you'll have. I certainly believed that. Conventional sports nutrition books had me convinced of it. Yet, in practice, we see that clearly isn't the case.

Stress is like fire: When controlled and used for a purpose, it serves us well. Left unbridled, it can consume us.
