Andrew Weil, MD (@DrWeil) is a pioneer in the field of integrative medicine. He has been named one of the 100 most influential people in the world by Time magazine.

Dr. Weil received a degree in biology (botany) from Harvard College in 1964 and an MD from Harvard Medical School in 1968. From 1971 to 1975, as a fellow of the Institute of Current World Affairs, Dr. Weil traveled widely in North and South America and Africa collecting information on drug use in other cultures, medicinal plants, and alternative methods of treating disease. From 1971 to 1984 he was on the research staff of the Harvard Botanical Museum and conducted investigations of medicinal and psychoactive plants.

Dr. Weil is the founder and director of the Andrew Weil Center for Integrative Medicine at the University of Arizona, where he also holds the Lovell-Jones Endowed Chair in Integrative Medicine and is Clinical Professor of Medicine and Professor of Public Health. Through its fellowship and Integrative Medicine in Residency curricula, the Center is now training doctors and nurse practitioners around the world.

A New York Times best-selling author, Dr. Weil has written 15 books on health and well-being, including Mind Over Meds; Fast Food, Good Food; True Food; Spontaneous Happiness; Healthy Aging; and Eight Weeks to Optimum Health. He is also co-founder of the restaurant chain True Food Kitchen and co-founder of Matcha.com, which offers extremely high-quality matcha that is difficult to find outside of Japan.

This episode is brought to you by Levels! I wrote about the health benefits of using continuous glucose monitors (CGMs) more than ten years ago in The 4-Hour Body. At the time, CGMs were primitive and hard to use. Levels has now made this technology, and the unique insights that come from it, easy and available to everyone. Levels is making glucose monitoring simple, helping you see how food affects your health through real-time feedback. I started tracking my glucose years ago to learn more about what I should and shouldn’t be eating (including quantities, time of day, etc.), based on objective data from my own, unique physiology. Keeping my blood sugar stable is critical to my daily and long-term health and performance goals. Furthermore, poor glucose control is associated with a number of chronic conditions like diabetes, Alzheimer’s disease, heart disease, and obesity. It’s important.

If you’re interested in learning more about Levels and trying a CGM yourself, go to Levels.link/Tim.

This episode is also brought to you by LMNT! What is LMNT? It’s a delicious, sugar-free electrolyte drink mix. I’ve stocked up on boxes and boxes of this and usually use it 1–2 times per day. LMNT is formulated to help anyone with their electrolyte needs and perfectly suited to folks following a keto, low-carb, or Paleo diet. If you are on a low-carb diet or fasting, electrolytes play a key role in relieving hunger, cramps, headaches, tiredness, and dizziness.

LMNT came up with a very special offer for you, my dear listeners. For a limited time, you can get a free LMNT Sample Pack with any purchase. This special offer is available here: DrinkLMNT.com/Tim.

This episode is also brought to you by Athletic Greens. I get asked all the time, “If you could use only one supplement, what would it be?” My answer is usually AG1 by Athletic Greens, my all-in-one nutritional insurance. I recommended it in The 4-Hour Body in 2010 and did not get paid to do so. I do my best with nutrient-dense meals, of course, but AG further covers my bases with vitamins, minerals, and whole-food-sourced micronutrients that support gut health and the immune system. 

Right now, Athletic Greens is offering you their Vitamin D Liquid Formula free with your first subscription purchase—a vital nutrient for a strong immune system and strong bones. Visit AthleticGreens.com/Tim to claim this special offer today and receive the free Vitamin D Liquid Formula (and five free travel packs) with your first subscription purchase! That’s up to a one-year supply of Vitamin D as added value when you try their delicious and comprehensive all-in-one daily greens product.
