The goal of my diet-style is eating for optimal health and longevity. What greater benefit could there be than living healthfully and actively into old age with no dependence on medications and almost no risk of heart disease, diabetes or dementia?

You need to eat normally and healthfully, and you need to exercise. I'm so passionate about this because I think people spend their lives not happy in their bodies.

Developing a diet that is healthful, balanced, and appropriate for your particular caloric needs is easy enough and is absolutely critical to establishing a healthful lifestyle that incorporates proper nutrition, adequate fitness, and mental resilience.

Nuts have gotten a bad rap because of their high fat content. But their protein, heart-healthy fats, high fibre, and antioxidant content earn them a place in your daily diet. I often say 'less is more,' and portion control is key to healthfully enjoying nuts.

The best diet for overall health, and specifically for heart, brain, and cancer risk reduction, is a diet that's aggressively low in carbohydrates with an abundance of healthful fat, and this is the central theme of 'Grain Brain.'

The best diet is the one that can be sustained over the long term, combined with other healthful lifestyle behaviors.

A healthful hunger for a great idea is the beauty and blessedness of life.
