Protein is everywhere these days. Walk down any grocery aisle and you'll see "high protein" splashed across cereal boxes, snack bars, and even ice cream. Scroll through social media, and influencers are preaching about protein powder. But with all this noise, what does the science actually say about protein's role in weight management?

If you've ever wondered whether protein really lives up to the hype or if you're struggling with constant hunger, afternoon snacking, or hitting weight loss plateaus, this episode cuts through the confusion. You'll discover the research-backed truth about how much protein you actually need, when to eat it for maximum benefit, and why your breakfast might be the key to controlling your appetite all day long.

When your weight loss plateaus don't make sense, when your labs are worse than expected, or when your clothes fit better but the scale won't budge, there might be an invisible culprit working against you. Low-grade inflammation isn't just about sore throats or swollen joints. It's a silent saboteur that can reshape how your fat cells function, how your body responds to insulin, and how your metabolism adapts to change.

But here's the empowering truth: inflammation isn't something that just happens to you. There are real, science-backed strategies you can implement starting today to reduce it and transform your metabolic health, regardless of what the scale says.

Join Holly and Jim as they delve deep into the hidden world of inflammation with Dr. Philipp Scherer, one of the world's most respected obesity researchers and Professor of Internal Medicine at UT Southwestern Medical Center. Dr. Scherer has revolutionized how we understand fat tissue, not as passive storage, but as a highly active organ that controls hormone signaling and metabolic health. If you've heard of metabolically healthy obesity or wondered why some people carry weight better than others, you've encountered the impact of his groundbreaking research.
