Weight Loss And ...

If you've ever been told lifestyle change is the key to losing weight, this episode might make you rethink the job we've been asking lifestyle to do. Now that powerful medications can produce substantial weight loss, what is healthy eating and movement really for?

Join Holly and Jim as they sit down with Dr. Gary Foster, a clinical psychologist who has spent decades studying behavioral weight management. He has led academic research programs, served as chief science officer at WW (formerly Weight Watchers), and is now chief scientific officer and head of clinical and medical affairs at...

What if the medications that were supposed to fix obesity turned out to be just the beginning of the story? After decades of studying weight loss, Holly and Jim thought they had seen it all. Then a new class of medications arrived and overturned some of their most basic assumptions.

In this episode, each of them brings five things that genuinely surprised them about the GLP-1 era. Some are about the science, some are about what they see in patients, and some are about what these medications were expected to solve but haven't. Two longtime experts admit...

You’ve hit your goal weight, or you’re close. So why doesn’t life feel as different as you expected? For many people, the number on the scale was never really the point. It was a stand-in for feeling confident, joining in, and finally enjoying life.

Today’s weight loss medications are helping people lose weight that once felt out of reach. A large new BMJ analysis asked whether quality of life is keeping pace, and the answer may make you rethink what success means. Join Holly and Jim as they dig into the findings, why feeling...

Your friend just started semaglutide. She got it online; it's "compounded," it has B12 in it, and it's only $199 a month. Sounds like a great deal, right? But what exactly is in that vial, who made it, and how much are you supposed to take? More and more people are facing these questions every day, and most of us don't know how to answer them.

Join Holly and Jim as they welcome not one, not two, but three guests for the very first time: Misty Gaddis, pharmacy manager of medication compounding safety; Jessica Pescatore, clinical director of...

New obesity medications can now produce weight loss once thought impossible without surgery. That success is forcing doctors to ask a question they never had to face before: what if a treatment doesn't know when to stop?

Join Holly and Jim as they unpack six new questions these next-generation drugs have raised in obesity medicine. Using a relatable patient case, they explore the difference between losing the maximum amount of weight and losing the optimal amount, and why those two things are no longer the same. You'll also hear where lifestyle fits into treatment now, what "...

If losing weight made movement easier, wouldn’t you naturally start moving more? It’s the kind of assumption that feels almost too obvious to question: shed 40 or 50 pounds, and your knees stop aching, the stairs get easier, and you’re out there living more. Holly and Jim certainly believed it. But in the age of GLP-1 medications, where rapid, substantial weight loss is now common, does this assumption still hold up?

In this episode, Holly and Jim put that belief to the test with real data. Diving into three separate studies (including brand-new, cutting-edge research), they e...

Everyone knows GLP-1 medications help people eat less. But does eating less actually mean eating better? It’s a question the weight loss field never really had to ask before, and the answer might surprise you.

Join Holly and Jim as they dig into three GLP-1 studies looking at what people are actually eating. You’ll hear the real numbers behind diet quality, protein intake, and nutrient gaps on these medications, plus what it means for anyone currently taking (or considering) a GLP-1. Holly and Jim also share five practical tips to help ensure your diet works as h...

Think you know what it takes to keep weight off? Most people can tell you how to lose weight, but ask them what actually predicts keeping it off, and the answers get shaky fast. That’s a problem, because losing weight and maintaining weight loss are two completely different biological and behavioral games, and confusing the two is one of the biggest reasons people yo-yo.

In this episode, Holly and Jim put their listeners to the test literally. They’ve built a 20-question pop quiz covering everything from the hidden biology of metabolic adaptation to the real find...

What did humans actually evolve to eat? With paleo, keto, vegan, Mediterranean, and a thousand other diets all claiming to be "the one," it's no wonder people feel whiplashed every time they walk into a grocery store. But what if the answer isn't found in the latest diet book, but in millions of years of human evolution?

Join Holly and Jim as they welcome back Harvard evolutionary biologist Dan Lieberman for a second appearance on the show. This time, Dan isn't talking exercise. He's talking food. Drawing on his new book, "Fed Up: What Evolution Reveals About...

Most people trying to lose weight obsess over the what: what diet, what medication, what workout plan. But according to Holly and Jim, the real key to long-term success isn't found in any of those choices. It's found in a set of decisions most people never even realize they're making.

In this episode, Holly and Jim count down the 10 decisions that determine whether a weight loss journey actually sticks. Some are questions you'd expect. Others might catch you completely off guard, including the one they say most listeners will never predict is number one.

Whether...

For years, the ceiling on medical weight loss was 15%, maybe 20% if you were lucky. Now a new triple-target medication is posting average results that flirt with 30% body weight loss in clinical trials, numbers once reserved for the operating room. Holly and Jim sat down to unpack what's driving these results, and found themselves asking a question neither expected to ask in their careers: how much weight loss is actually too much?

Retatrutide, the drug at the center of this episode, adds a third receptor target to the GLP-1 and GIP combination already familiar to listeners. Holly and...

Can simply paying attention to your first bite of food change how much you eat? It sounds too simple to matter, but Holly and Jim are digging into a topic that might seem completely outside their lane: mindfulness and meditation.

For years, mindfulness has been filed under "stress management," not "weight management." But a growing body of research is asking a bigger question: can training the mind actually change the way we eat, not by altering our biology, but by changing how we respond to it? Holly and Jim break down a recent meta-analysis of dozens of...

A few clicks online. No exam, no phone call, no video visit. Minutes later, a GLP-1 prescription is headed to your door. It sounds like the future of healthcare: fast, easy, convenient. But is convenience the same thing as care?

A Yale research team wanted to find out, so they built a fake patient, sent her to 49 different online GLP-1 providers, and tracked exactly what happened. What they found may change the way you think about getting these medications online and raise questions you didn't know to ask.

Join Holly and Jim as they unpack...

For years, patients kept telling Holly the same strange thing: it wasn't the number on the scale that changed their life, it was something quieter, something they'd never had words for. They just didn't think about food anymore.

Now that experience has a name, and for the first time, a way to measure it. Food noise has gone from an offhand comment on social media to one of the most talked-about concepts in obesity science, and Holly and Jim are back to unpack how far the research has come since they last covered it.

Join...

GLP-1 medications are the single most requested topic on the show, no contest. But with so much noise on social media, in doctors' offices, and everywhere in between, sorting fact from fiction has never been trickier. Some of what's out there is spot-on. Some of it is dangerously wrong.

So this week, Holly and Jim are flipping the format. Instead of another lecture, they're putting GLP-1 knowledge to the test with a 20-question quiz covering everything from the basic biology of these medications to the questions doctors themselves don't always get right. Grab a pen, keep score...

We've all felt it: you decide to eat healthier, open social media, and within minutes, you're drowning in contradictory advice. Eggs are back. Butter's healthy. Seed oils are toxic. Never eat after 7pm. Wait, only eat between noon and 6pm? By the end, you're left wondering if anyone can just tell you what to eat.

Join Holly and Jim as they sit down with award-winning food journalist and registered dietitian Carolyn O'Neil to unpack why nutrition advice feels so exhausting and contradictory. With decades spent translating nutrition science for CNN and beyond, Carolyn has made a career...

Cancer is the disease most people fear. But heart disease is the one that actually kills the most Americans, and most people never connect it to their weight. For decades, obesity was treated as a bystander to heart disease, a risk factor at best. That thinking has changed dramatically, and the data behind that shift is stunning: we now have a medication proven to cut major cardiovascular events by 20% in people with obesity.

Join Holly and Jim as they sit down with an old friend and true legend in the field, Dr. Robert Eckel, Professor Emeritus...

For decades, one number has ruled the world of fitness: 10,000 steps. It's on your watch, your phone, maybe even tattooed into your daily to-do list. But what if that number was never based on science at all?

Join Holly and Jim as they sit down with Dr. Amanda Paluch, Associate Professor of Kinesiology at the University of Massachusetts Amherst and leader of the Steps for Health Collaborative, an international research consortium pooling data from over 125,000 adults to answer one deceptively simple question: how many steps do you actually need? Amanda pulls back the curtain on where the 10,000...

For 40 years, every time nutrition has found a new villain, the food industry has handed us a new label to go with it: non-fat, no GMOs, gluten-free, no seed oils, and now, non-ultra-processed. We have more experts, more studies, and more food rules than ever before, so why does standing in the grocery aisle still feel like such a guessing game?

Join Holly and Jim as they sit down with Tamar Haspel, the James Beard Award-winning Washington Post columnist behind Unearthed and author of To Boldly Grow, to pull apart the ultra-processed food debate and ask whether...

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 why a stalled scale is actually a sign the medication is doing...

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 explore one of the most important  and most overlooked dimensions o...

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 history. From the 1930s to the GLP-1 era...

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 most eye-opening conversations in the GLP-1 era. Maha has spent decades at the crossroads of nutrition science...

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. Ken Fujioka, an endocrinologist, director of the Nutrition and Metabolic Research Center at Scripps Clinic, and one of...

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 them, and why the U.S. and Europe keep landing in different places? In this episode, Holly and...

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 no one told you what was missing.<...

Exercise is good for you. But good for your mood? Your brain? Science has now weighed in, and the answer might surprise you more than you'd expect.

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 experience, and why it's time to prioritize exercise for your mind.

Along the way, Holly and...

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 people, this "common sense" doesn't align with their lived experience, and there's a biological reason...

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 explore this new frontier. If you've ever struggled to stick with...

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 biological one. And his groundbreaking work laid the foundation for the very GLP-1 medications making...

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 — and more importantly, why we so often 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 scientific advisory committee actually concluded after two years of rigorous, volunteer-driven research. The result? A lot of frustrated scientists an...

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 game, throwing out the statements they hear most often in the clinic, on social media...

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, a rising star whose cutting-edge research is changing how we think...

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 whispering that they're on drugs at all. Some are obsessing over microdosing, while still others are wondering if...

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 sooner you can build something that actually works for you. This...

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 work" when the real issue was never the medication at all. Join Holly and...

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 battles? Join Holly and Jim as they sit down with Bi...

Have you ever done everything right, eaten well, moved your body, maybe even started a new medication, and still felt like the system wasn’t working for you? You’re not alone. And the reason might not be what you think.

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. Dr. Stanford treats obesity as the complex, chronic disease it truly is, and she’s not afraid to call o...

New Year’s resolutions often start with motivation and willpower, but how long does that really last? What if the problem isn’t your discipline, but the world you’ve built around yourself? Your refrigerator, your bedroom setup, even the people you spend time with, are quietly shaping every choice you make.

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 social circle to make healthy choices the easy ones. You’ll learn how your...
