EFR 968: Fatty Liver Disease: How to Prevent and Reverse Liver Damage with Dr. Mike Smith

Fatty liver disease is becoming increasingly common—but liver damage can develop quietly, sometimes before obvious symptoms or abnormal liver enzymes appear. Today we welcome Dr. Mike Smith, MD to break down liver health, fatty liver disease, nonalcoholic fatty liver disease (NAFLD), metabolic dysfunction-associated steatotic liver disease (MASLD), cirrhosis, liver inflammation, and the everyday factors that may be putting additional stress on your liver.

Dr. Mike explains how fat begins accumulating in the liver, how liver inflammation and cellular damage can progress toward fibrosis and eventually cirrhosis, and why fatty liver disease isn't only a concern for people who drink alcohol. The conversation explores the metabolic and lifestyle factors associated with poor liver health—including excess calories, visceral fat, refined sugar, highly processed foods, alcohol, environmental exposures, medications, metabolic dysfunction, poor sleep, and chronic stress.

We also unpack one of the biggest challenges surrounding fatty liver disease: you may not know you have it. Dr. Mike discusses vague symptoms including fatigue, brain fog and gastrointestinal issues, why standard liver enzyme testing doesn't necessarily tell the entire story, and when additional evaluation such as liver imaging may become relevant.

You'll also learn how the liver processes what you eat and drink through the body's "first pass" system, why metabolic health is so closely connected to liver health, and practical strategies discussed in the episode for supporting healthy liver function through nutrition, exercise, reducing environmental exposures, and appropriate supplementation.

We also explore the relationship between magnesium and liver health, including magnesium's role in liver reactions involved in detoxification and the broader importance of adequate magnesium status. Dr. Mike discusses magnesium alongside milk thistle, curcumin and foundational dietary strategies as part of a broader—not single-supplement—approach to liver health.

If you've ever wondered about the symptoms of fatty liver disease, whether fatty liver can be reversed, what causes nonalcoholic fatty liver disease, how MASLD develops, how fatty liver progresses toward cirrhosis, or what you can do today to better protect your liver, this episode is your deep dive into one of the body's most important—and often overlooked—organs.
