Losing weight on a GLP-1 medication can feel like magic until the scale stops moving. For almost everyone on these drugs, there comes a moment when the rapid progress slows, then stalls completely. Is the medication failing? Has your metabolism adapted? Did you do something wrong? For most people, that moment feels like a problem. It isn't. Join Holly and Jim as they unpack one of the most misunderstood parts of the GLP-1 journey: the shift from losing weight to keeping it off. You'll discover w...

What if the biggest obstacle to your health isn't your willpower, it's your zip code? Most of us have been raised to believe that weight and health come down to personal choices: what you eat, how much you move, how disciplined you are. But what if the deck has been stacked against millions of Americans before they ever make a single decision? This week, Holly and Jim sit down with Dr. Christina Economos, Dean of the Friedman School of Nutrition Sciences and Policy at Tufts University, to explor...

If you've spent years hopping from one diet to the next: low fat, then low carb, then keto, then intermittent fasting, you're not alone, and you're not failing. The truth is, the diet world has been cycling through the same promises, the same villains, and the same disappointments for nearly a hundred years. And most of us never stop to ask why. Join Holly and Jim as they do something they've never done before on the show: step back and take a decade-by-decade look at almost 100 years of dieting...

Millions of people are now taking GLP-1 medications and losing weight, but is eating less the same as eating better? The answer, according to today's guest, is a resounding no. And almost nobody in medicine, food, or public health is talking seriously about what happens when appetite disappears, but nutritional needs don't. Join Holly and Jim as they sit down with Dr. Maha Tahiri, a nutrition scientist, food industry strategist, and founder of Nutrition Sustainability Strategies, for one of the ...

What if the medications changing everything about obesity treatment are also creating problems nobody saw coming? We’re living through a genuine before-and-after moment in obesity medicine. Drugs that once seemed like science fiction are now producing 20, even 25% weight loss in real patients. But the questions piling up are just as staggering as the results: What happens to your muscle? Your bone? Your sense of self? And what happens when the medication stops? Holly and Jim sit down with Dr. Ke...

Everyone has been burned by nutrition advice that completely reversed itself a few years later. Eggs were dangerous, then essential. Butter was poison, then practically a health food. Fat was the enemy until we realized what replaced it might have been even worse. If you've ever thrown up your hands and wondered whether nutrition scientists agree on anything , you're not alone. What if the confusion isn't just about changing science but about how nutrition guidelines are made, who influences the...

You've heard it before. A friend, a coworker, or your own mother swears by something, and the proof is standing right in front of you. She lost 30 pounds. You've seen it. You know it's real. So why aren't you doing it too? Here's the thing: personal success stories are powerful precisely because they're real. But real doesn't mean the whole picture. And in the world of weight loss, acting on the wrong part of a true story can quietly pull you off track, not because you were fooled, but because n...

Join Holly and Jim as they dig into the most comprehensive review ever conducted on exercise and depression, a sweeping 2026 Cochrane analysis of 73 randomized controlled trials and nearly 5,000 people. This isn't feel-good advice; it's hard data. Discover why taking action through movement can benefit your mental health, no matter your role or exp...

Have you ever wondered why the same advice that worked perfectly for your friend did absolutely nothing for you? What if the problem isn't your effort, your commitment, or even the advice itself, but rather the body you're living in? Holly and Jim tackle one of the most misunderstood topics in weight management: the gap between what feels obviously true and what's actually universal. If you've never struggled with your weight, some things just seem like common sense. However, for millions of peo...

For decades, the message has been simple: if you want to lose weight, you need to exercise more. But what happens when a medication can do the heavy lifting for you? GLP-1 drugs are reshaping everything we thought we knew about weight loss, and that means the role of exercise is changing, too. Not disappearing. Changing. Join Holly and Jim as they sit down with Dr. Renee Rogers, senior scientist at the University of Kansas Medical Center and expert in biobehavioral lifestyle interventions, to ex...

You hit your goal weight. Then, hunger crept back in, your energy dropped, and the scale rose. Sound familiar? You're not broken, your body is built for this. In this episode, Holly and Jim sit down with Dr. Rudy Leibel, one of the most influential obesity researchers in history, a Columbia University scientist whose team cloned the leptin gene and fundamentally changed the world's understanding of obesity. What was once dismissed as a willpower problem, Dr. Leibel helped prove is a deeply biolo...

You've probably told yourself the story before: "I'm just lazy. I should want to exercise. Something must be wrong with me." But what if science says you're not lazy at all? What if avoiding the treadmill is one of the most deeply human things you can do? This week, Holly and Jim are joined by Dr. Daniel Lieberman, professor of human evolutionary biology at Harvard University and author of The Story of the Human Body and Exercised . Dan has spent his career studying why humans move the way we do...

Every five years, the U.S. government releases dietary guidelines that shape what gets served in school cafeterias, what doctors recommend to patients, and what ends up on your plate. But what actually happens behind the scenes, and who really gets the final say? If you've ever felt confused about protein, carbs, red meat, or dairy, you're not alone. The latest 2025–2030 Dietary Guidelines for Americans arrived with controversy baked in, with final recommendations that diverged from what the sci...

Everything you think you know about weight loss might be wrong, and that's actually great news. From "my metabolism is broken" to "I just need more willpower," the weight loss world is full of statements that sound completely reasonable, get repeated constantly, and quietly keep people stuck. The problem isn't that people aren't trying hard enough. It's that they're working from a playbook full of myths, half-truths, and oversimplifications. Join Holly and Jim as they turn the podcast into a gam...

You already know that what you eat matters. But what about how you season it? Most of us reach for the salt shaker without a second thought, but hiding in your spice rack right now could be some of the most powerful, most overlooked tools in nutrition science. Join Holly and Jim as they sit down with two leading researchers from Penn State University, Dr. Penny Kris-Etherton, one of the most decorated nutrition scientists in the field of diet and cardiovascular health, and Dr. Kristina Petersen,...

The questions people asked about GLP-1 medications a year ago: Do they work? Are they safe? has been answered. However, a new wave of questions is now emerging, and they're more complex, personal, and in some cases, more surprising than anyone had expected. Something has shifted in the conversation, and Holly and Jim are paying close attention. When the questions change, that's where the real tension lives. People on these medications are reporting feeling emotionally flat. Others are quietly wh...

Most people spend years chasing the “right” weight loss plan, the one diet, the one program, the one secret that finally makes everything fall into place. But what if the reason nothing has stuck isn’t a lack of willpower or effort? What if it’s because you’ve been following someone else’s plan? Holly and Jim are pulling back the curtain on one of the most liberating truths in weight loss science: maintenance isn’t one-size-fits-all, and the sooner you stop looking for a universal formula, the s...

If you're on a GLP-1 medication or thinking about starting one, there's a good chance you're only seeing half the picture. The media is full of before-and-after stories, but what happens after the after? Most people don't find out until it's too late. The truth is, GLP-1 medications are genuinely remarkable tools. But tools only work when you know how to use them. And right now, millions of people are stopping their medications, regaining the weight, and walking away convinced the drugs "didn't ...

Weight loss isn’t just about the number on the scale. It’s about reclaiming your life. When you’ve been carrying excess weight for years, it’s easy to start accepting limitations as your new normal. Skipping events because of walking. Staying in the car while others explore. Wondering if you’ll see your future grandchildren grow up. But what if the right support could help your body work with you instead of against you? What if losing weight didn’t have to mean constant hunger and willpower batt...

Join Holly and Jim as they sit down with Dr. Fatima Cody Stanford, an obesity medicine physician and associate professor at Harvard Medical School, and one of the boldest voices shaping how we think about obesity care today.

Join Holly and Jim as they reveal why an environmental detox might be the smartest move you can make this year. Forget juice cleanses and deprivation, this is about redesigning your space and ...

Going vegan for weight loss? You might be in for a surprise. Despite what social media influencers claim, switching to a plant-based diet doesn’t guarantee the pounds will melt away. In fact, many vegans struggle with weight gain even when they think they’re eating healthy. The truth is, whether you’re eating steak or tofu, the same principles of weight management still apply. You can absolutely lose weight and thrive on a vegan diet, but it requires the same intentionality, planning, and unders...

The GLP-1 medications transforming weight loss didn’t appear overnight. They’re the result of decades of groundbreaking research that fundamentally changed how we understand appetite and obesity. But how did scientists first discover that this hormone could help people lose weight? And what does this history mean for anyone using these medications today? Join Holly and Jim as they sit down with Dr. Arne Astrup, one of the pioneering researchers who helped uncover GLP-1’s role in appetite regulat...

Food noise. If you’ve heard the term, you probably know exactly what it means. If you haven’t, you might be about to have a lightbulb moment. It’s that relentless mental chatter about food, not hunger, not cravings, but constant, unwanted thoughts that just won’t quit. For years, people struggling with this phenomenon didn’t even have words for it. They thought it was a willpower problem. It wasn’t. And now, thanks to groundbreaking research, we finally have a way to understand, measure, and pot...
