It is more important to eat some carbohydrates at breakfast, because the brain needs fuel right away, and carbohydrate is the best source.

By keeping my hand in that, it's the way I keep learning. The main way you learn in medicine is by practicing and working with patients.

You've got to experiment to figure out what works.

Get people back into the kitchen and combat the trend toward processed food and fast food.

It is more important to eat some carbohydrates at breakfast, because the brain needs fuel right away, and carbohydrate is the best source.

Pay attention to your body. The point is everybody is different. You have to figure out what works for you.

The best way to detoxify is to stop putting toxic things into the body and depend upon it's own mechanisms.

A beautiful bouquet or a long-lasting flowering plant is a traditional gift for women, but I have recommended that both men and women keep fresh flowers in the home for their beauty, fragrance, and the lift they give our spirits.

American businesses are struggling to pay outrageous, exploitive insurance bills for their employees, hampering our ability to compete globally.

As an undergraduate at Harvard in the 1960s, I was fascinated by my visits to psychologist B.F. Skinner's laboratory.

As any doctor can tell you, the most crucial step toward healing is having the right diagnosis. If the disease is precisely identified, a good resolution is far more likely. Conversely, a bad diagnosis usually means a bad outcome, no matter how skilled the physician.

Conscious breath control is a useful tool for achieving a relaxed, clear state of mind.

Dietary fat, whether saturated or not, is not a cause of obesity, heart disease or any other chronic disease of civilization.

Each day as I travel through downtown Tucson, I am amazed at how quickly the most ancient of human behaviors have changed. For as long as there have been Homo sapiens - roughly 200,000 years - people have filled their lives principally with two activities: talking directly with other people, and doing physical things.

Everyone prefers some foods over others, but some adults take this tendency to an extreme. These people tend to prefer the kinds of bland food they may have enjoyed as children - such as plain or buttered pasta, macaroni and cheese, cheese pizza, French fries and grilled cheese sandwiches - and to restrict their eating to just a few dishes.

Excess exercise tends to be counterbalanced by excess hunger, exemplified by the phrase 'working up an appetite.' A few people with extraordinary willpower can resist such hunger day after day, but for the vast majority, weight loss through exercise is a flawed option.

Fear and greed are potent motivators. When both of these forces push in the same direction, virtually no human being can resist.

Fitting a walk into a busy life can be challenging, so I suggest walking rather driving to work or to run errands as often as you can - in other words, think of walking as alternative transportation.

For many in the modern world, carving out time for both traditional seated meditation and exercise has become close to impossible.

Gardening is not trivial. If you believe that it is, closely examine why you feel that way. You may discover that this attitude has been forced upon you by mass media and the crass culture it creates and maintains. The fact is, gardening is just the opposite - it is, or should be, a central, basic expression of human life.

Genuine happiness comes from within, and often it comes in spontaneous feelings of joy.

Giving gifts to others is a fundamental activity, as old as humanity itself. Yet in the modern, complex world, the particulars of gift-giving can be extraordinarily challenging.

Human beings and plants have co-evolved for millions of years, so it makes perfect sense that our complex bodies would be adapted to absorb needed, beneficial compounds from complex plants and ignore the rest.

Human bodies are designed for regular physical activity. The sedentary nature of much of modern life probably plays a significant role in the epidemic incidence of depression today. Many studies show that depressed patients who stick to a regimen of aerobic exercise improve as much as those treated with medication.

I am a particular fan of integrative exercise - that is, exercise that occurs in the course of doing some productive activity such as gardening, bicycling to work, doing home improvement projects and so on.

I have argued for years that we do not have a health care system in America. We have a disease-management system - one that depends on ruinously expensive drugs and surgeries that treat health conditions after they manifest rather than giving our citizens simple diet, lifestyle and therapeutic tools to keep them healthy.

I'm still not comfortable recommending that people eat saturated fat with abandon, but it's clear to me that sugar, flour and oxidized seed oils create inflammatory effects in the body that almost certainly bear most of the responsibility for elevating heart disease risk.

If the only way you could read an email was to run a mile first, the urge would quickly die. Human beings constantly do subconscious effort/reward calculations. Tapping a screen is the easiest of physical tasks.

If we can make the correct diagnosis, the healing can begin. If we can't, both our personal health and our economy are doomed.

If you have difficulty sleeping or are not getting enough sleep or sleep of good quality, you need to learn the basics of sleep hygiene, make appropriate changes, and possibly consult a sleep expert.

In the world at large, people are rewarded or punished in ways that are often utterly random. In the garden, cause and effect, labor and reward, are re-coupled. Gardening makes sense in a senseless world. By extension, then, the more gardens in the world, the more justice, the more sense is created.

Limit or eliminate late-night computer and television viewing. A computer or TV screen may seem much dimmer than a light bulb, but these screens often fill your field of vision, mimicking the effects of a room filled with light.

Many exercise forms - aerobic, yoga, weights, walking and more - have been shown to benefit mood.

Massage therapy has been shown to relieve depression, especially in people who have chronic fatigue syndrome; other studies also suggest benefit for other populations.

Millions of Americans today are taking dietary supplements, practicing yoga and integrating other natural therapies into their lives. These are all preventive measures that will keep them out of the doctor's office and drive down the costs of treating serious problems like heart disease and diabetes.

My passion for gardening may strike some as selfish, or merely an act of resignation in the face of overwhelming problems that beset the world. It is neither. I have found that each garden is just what Voltaire proposed in Candide: a microcosm of a just and beautiful society.

One of the most obvious ways dogs can improve our physical and mental health is via daily walks.

Remember that breath walking - as with any meditation technique - should not be pursued with a grim determination to 'get it right.' The point is to cultivate openness, relaxation and awareness, which can include awareness of your undisciplined, wandering mind.

Shorter daylight hours can affect sleep, productivity and state of mind. Light therapy, also known as phototherapy, may help. It uses light boxes emitting full-spectrum light to simulate sunlight.

Studies have shown that people who are physically active sleep better than those who are sedentary. The more energy you expend during the day, the sleepier you will feel at bedtime.

Technology has a shadow side. It accounts for real progress in medicine, but has also hurt it in many ways, making it more impersonal, expensive and dangerous. The false belief that a safety net of sophisticated drugs and machines stretches below us, permitting risky or lazy lifestyle choices, has undermined our spirit of self-reliance.

The World Health Organization has recognized acupuncture as effective in treating mild to moderate depression.

The bottom line is that the human body is complex and subtle, and oversimplifying - as common sense sometimes impels us to do - can be hazardous to your health.

The more easily digestible and refined the carbohydrates, the greater the effect on our health, weight and well-being.

The more people have, the less content they seem to be. In America, the cultural expectation that we're to be happy all the time and our children are to be happy all the time is toxic, and I think that really gets in the way of emotional well-being.

The most common objection that I hear to walking as exercise is that it's too easy, that only sweaty, strenuous activity offers real benefits. But there is abundant evidence that regular, brisk walking is associated with better health, including lower blood pressure, better moods and improved cholesterol ratios.

The usual justification for eating extra meals is that it keeps the metabolism 'revved up' so that weight loss is easier. There is, however, very little hard evidence that supports this idea, and a fair amount that disputes it.

The world is beset by many problems, but in my opinion, this hijacking of our brain's reward centers by electronic media is potentially one of the most destructive.

There's a great deal of scientific evidence that social connectedness is a very strong protector of emotional well-being, and I think there's no question that social isolation has greatly increased in our culture in, say, the past 50 years, past 100 years.
