I'm thinking of people in rural Japan and China, where McDonald's hasn't yet arrived. These are the thinnest, healthiest, longest-lived people with the least risk of cardiovascular disease and diabetes.

Meat consumption is just as dangerous to public health as tobacco use... It's time we looked into holding the meat producers and fast-food outlets legally accountable.

I think we have to do everything that's useful. We're doctors. Our job is to tell the truth. And it doesn't have to be embellished in any way.

Dogs have a sense of smell much greater than ours and they're much faster than we are. We have fairly dull senses, fairly slow locomotion. In our Olympic trials, we celebrate speeds that would be an embarrassment to a bird or a dog or another animal.

I thought - being a musician doesn't help your medical credibility really. Although I started to rethink that when I learned that Albert Einstein was quite a violinist and in fact would perform a lot with symphonies. So if it's good enough for Albert, it's good enough for me.

People do lose weight on an Atkins diet. The reason they lose weight is because of calorie reduction. If a person's caloric intake has not fallen, if they are really shoveling in the steak, they don't lose weight.

In China, because China is gaining wealth, rice consumption is way down. Rice is a poor person's food, and they're eating less of it. To wait in line at a fast food chain is cool. And they haven't historically had weight problems. So they don't have this culture of, "I need to lose weight."
