In fact, the number one reason for obesity in North America is simple: over consumption. And we over consume because we're hungry.

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.

It's not volume, nor is it calories that we biologically hunger for. It's micronutrients. And until we receive enough, the hunger signal will continually urge us to eat. Thankfully, there's a simple fix: nutrient-dense food.

Once I learned how to be a healthy vegan by eating the right foods my performance improved dramatically.

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.

The closest you can get to perfection is constant improvement.

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