The Hidden Reason You Feel Exhausted & How to Feel Better Now
If you’ve been feeling exhausted, tired, bloated, anxious, in pain, or just not like yourself, get ready for an explanation you’ve never heard before.
Today, Mel sits down with one of the most respected medical researchers in the world, gastroenterologist Dr. Brennan Spiegel, MD, to uncover the overlooked, invisible force that’s having a shocking impact on your energy, strength, gut health, mood, and every single cell in your body – even how fast your body ages.
Whether you’re dealing with fatigue, back pain, swelling, digestion issues, or a heaviness in your body that you can’t shake, Dr. Spiegel says these are all signs you shouldn’t ignore.
Dr. Spiegel is a gastroenterologist and the director of Health Services Research at Cedars-Sinai Medical Center in Los Angeles, one of the leading medical centers in the United States. He is also a professor of medicine and public health at UCLA.
He trained at Cedars-Sinai and UCLA, and is a pioneering researcher in the areas of gut health, the usage of AI in medicine, and tools that help patients with pain, anxiety, and chronic illness.
He’s the founding editor of the Journal of Medical Extended Reality and he served as Editor-in-Chief of the American Journal of Gastroenterology. Dr. Spiegel has published more than 300 peer-reviewed scientific papers, his research has been cited 30,000 times, and he is the author of Pull: How Gravity Shapes Your Body, Steadies the Mind, and Guides Our Health.
What Dr. Spiegel reveals will challenge the way you think about your body and, more importantly, give you a completely new, practical way to start feeling better immediately. And it may give you the words and the insight you’ve been missing to help your aging parents and other loved ones finally start feeling better, too.
