Are ultra-processed foods the hidden reason weight loss feels impossible?

Chuck Carroll is joined by Dr. Jim Loomis, medical director at Barnard Medical Center, to break down the science behind ultra-processed foods and their powerful impact on weight gain, metabolism, hunger, and fat storage.

From packaged snacks and fast food to so-called "healthy" convenience items, ultra-processed foods now make up a majority of the modern diet. Dr. Loomis explains how these foods affect appetite hormones, blood sugar, calorie intake, and the body's ability to lose weight — and why simply "eating less" often doesn't work when ultra-processed foods dominate the plate.

You'll learn:

- What qualifies as an ultra-processed food - Why these foods drive overeating and cravings - How ultra-processed foods interfere with fat loss - The role of fiber, nutrients, and food quality in weight control - What to eat instead to support sustainable weight loss

Whether you're trying to lose weight, improve metabolic health, or understand why progress has stalled, this episode delivers practical, evidence-based answers.
