It is obvious now that diets don't work. People need to change their lives and lead more healthy lives.

Most of the people I see are very goal-directed, super achievers. That goal-driven mindset is very helpful if one uses it to lose weight and maintain weight.

If we eat better, if we eat in a more natural way — regardless of what our budget is, we all can do it — we realize it is possible to feel better, to look better, to make ourselves as healthy as we can be. That's the goal. For me it's all about health.

It is important for everyone to move every day, and what I prescribe is daily aerobic exercise of about an hour. Everyone says they don't have time for that. Even retired people say that. It doesn't change the fact that we need it. The body's got to move. If we don't move, that's when we get in trouble.
