Download MP3

These days, we hear a lot about fasting. Intermittent fasting, time-restricted eating, and water fasting are just some of the many terms being thrown around in support of better health. But which one is best? And what does it all mean for our longevity, brain health, and overall wellness?

Today on The Dhru Purohit Podcast, Dhru and Dr. Alan Goldhamer dive deep into the topic of water-only fasting: how it can troubleshoot our biology, boost our energy, and decrease our risk of disease.

Dr. Alan Goldhamer is one of the world’s leading experts on medically supervised, water-only fasting. In 1984, Dr. Goldhamer founded and became director of TrueNorth Health Center in Santa Rosa, California; since then, he has supervised the fasting and care of more than 20,000 patients. The center is the largest facility in the world specializing in medically supervised, water-only fasting, and it is one of the premier training facilities for doctors to gain certification in the supervision of therapeutic fasting.  

Dr. Goldhamer is the author of The Health Promoting Cookbook and coauthor of The Pleasure Trap—Mastering the Hidden Force that Undermines Health & Happiness. He is also the principal author of two landmark studies that showed evidence of the benefits of water-only fasting, as well as numerous case reports published in peer reviewed indexed journals evaluating the effects of water-only fasting in the treatment of a variety of conditions.
