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 exactly what it's supposed to do, and why "maintenance" is a completely different physiological state than "weight loss." One that comes with its own rules. Along the way, you'll pick up science-backed (and some still-unanswered) guidance on nutrition, muscle, bone health, and motivation for the long haul, plus a clear answer to a question Holly says she gets all the time: Are they against staying on these medications long-term?

Discussed on the episode:

• Why hitting a plateau on a GLP-1 is good news, not a sign the drug has stopped working.
• The blood pressure pill comparison that reframes what people call "drug resistance"
• Why nutrition may matter even more, not less, once weight loss stops
• Whether you actually need to exercise to keep weight off on a GLP-1 (the honest answer might surprise you)
• The bone health risk in younger women that's getting far less attention than muscle loss
• Why are dose-tapering and switching strategies being called the "Wild West" of GLP-1 care
• A New York Times claim about these medications "rewiring the brain" and what that could mean long after you stop.
• How to find motivation once the scale refuses to budge

Have a question or a success story? Send it in. Holly and Jim read every one, and they're especially looking for listener stories about navigating weight loss maintenance.

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 of the obesity epidemic: the environments we live in. With decades of groundbreaking research behind her, including the landmark Shape Up Somerville study, Dr. Economos makes a compelling case that lasting health change can't happen one person at a time.

And with GLP-1 medications reshaping what's possible for individual weight loss, the conversation has never been more urgent. Does community still matter when we have powerful new treatments? Dr. Economos has a clear answer, and it just might change how you see your own role in the bigger picture.

Discussed on the episode:

• The landmark study that proved community-wide obesity prevention actually works in the real world, and the surprising ripple effect it had beyond the children involved.
• Why your zip code may predict your health outcomes nearly as powerfully as your genetics
• The hidden forces in your neighborhood that are quietly shaping what you eat and how much you move, often without you realizing it
• What a food environment assessment in the Mississippi Delta revealed perfectly captures the challenge millions of Americans face daily
• Why fixing schools alone won't fix childhood obesity, and what actually needs to happen instead
• The honest answer to how much of the obesity epidemic is biology versus environment (hint: it's not a clean split)
• The key ingredients, Dr. Economos says, every successful community health intervention must have, and the #1 mistake researchers keep making
• How GLP-1 medications and community health are more connected than you might think
• What "spark plugs" are, why every successful health movement has had them, and whether you could be one
• Real U.S. communities that are getting this right and what they're actually doing differently
• Practical steps anyone can take right now, even if your environment is working against you

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 of today, they trace how we went from counting calories to carnivore diets  and what it all actually taught us (or didn't).

This one is equal parts fascinating, a little humbling, and surprisingly fun. Whether you're a diet history nerd or just someone who's tired of starting over, this episode will change the way you think about every diet you've ever tried.

Discussed on the episode:

• The three-category system Holly and Jim use to classify every diet, and why one category might describe your current eating plan
• The diet from the 1930s that your favorite wellness influencer is basically still selling today
• Why the decade that got everyone obsessed with fat-free foods may have actually made obesity worse
• The weight loss medication that came before GLP-1s, and the dramatic reason it was pulled from the market
• Which diets from the last 100 years actually have the science to back them up
• The rapid-fire verdict: best diet, biggest mistake, and most underrated program of the century
• What GLP-1 medications are changing about the way we think about diets, and why Holly has one big worry about where this is all heading
• Jim's closing thought that reframes everything you think you know about why diets succeed or fail

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, public health, and food innovation, and she's now helping companies around the world rethink what it means to nourish a consumer who's eating dramatically less. Her new company, S2B, is building a strategy for the GLP-1 era and beyond, and she's asking the questions that urgently need answers.

This episode will change how you think about GLP-1 medications, food, and what it truly means to be well-nourished.

Discussed on the episode:

• Why eating less on GLP-1s does NOT mean you're eating better and the nutritional crisis hiding in plain sight
• The alarming statistic about how many GLP-1 users are falling short on fiber, protein, and key micronutrients
• Why Maha calls what's happening to GLP-1 users "medically induced malnutrition" and why that phrase should get your attention
• The one behavior Holly says is now more important on GLP-1s than ever before (not what most people expect)
• Why fiber deserves its own strategy and why lumping it in with protein is a mistake.
• The three phases of GLP-1 use that should shape everything you eat
• What a strange debate in Botswana had to do with Maha's entire career pivot
• The unexpected food category that's actually thriving because of GLP-1 users
• Why the food industry may owe pharma a thank-you and what it needs to do with its second chance
• The role AI is now playing in nutrition advice, and why Maha thinks that's actually good news
• Maha's rapid-fire picks: the most underrated nutrient, the most overrated trend, and the one food she'd put in every kitchen.

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 the very first physicians to build an entire career around treating obesity, long before it was popular or even respected. He’s run over 100 clinical trials, treated thousands of patients a month, and watched this field go from Fen-phen clinics to GLP-1 breakthroughs. If anyone has the perspective to separate the genuine revolution from the hype, it’s Ken.

This episode is a masterclass in what actually happens in the exam room, not in a clinical trial, not in a headline, but with real patients facing real tradeoffs. Ken is refreshingly practical, deeply experienced, and not trying to win any argument. He’s just trying to help people build healthier lives in the middle of one of the fastest-moving moments medicine has ever seen.

Discussed on the episode:

• Why a shortage revealed a danger nobody was talking about, and why emergency rooms are still seeing the consequences
• The patients who are actually reaching their goal weight for the first time ever (and what that creates as the new problem to solve)
• What Ken tells patients who want to reduce or stop their medication, and the pattern he keeps seeing a few months later.
• The one group of patients he’s seen keeps the weight off without staying on the drugs, and what might explain it.
• Why losing weight faster is one of the biggest mistakes being made right now, and what the bariatric surgery literature has been telling us for years
• How Ken decides which medication to prescribe and why insurance coverage is always the first question
• The muscle loss conversation: why it’s like pulling teeth, and the one thing he’s considering making non-negotiable
• What the next generation of obesity drugs looks like, and the hormone that once seemed like a crazy idea that now has Ken most excited
• His rapid-fire answers: the most underrated obesity treatment tool, the biggest mistake clinicians make, and the one thing patients should protect above everything else
• The single thing Ken hopes every listener walks away remembering

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 Jim sit down with one of the world’s most influential nutrition scientists, Dr. Arne Astrup, to pull back the curtain on decades of dietary dogma, trace how some of our biggest nutritional mistakes happened, and explore where the science is actually heading.

Dr. Astrup has chaired the Nordic Nutrition Recommendations, led one of Europe's top nutrition research departments, and published over 700 scientific papers. He's also someone who has never been afraid to challenge the consensus, long before it was popular to do so. If you want to understand why nutrition science feels so chaotic, and what you should actually be eating, this conversation is your roadmap.

Discussed on the episode:

• The surprising historical event that set off decades of misguided dietary advice, and the real culprit that was overlooked
• Why the margarine push that replaced butter may have done far more damage than the food it was meant to replace
• The simple shift in thinking that makes navigating nutrition less complicated, not more
• Why Dr. Astrup says we should stop talking about saturated fat entirely
• The counterintuitive truth about full-fat cheese, yogurt, and eggs, and what the latest U.S. dietary guidelines finally got right
• A famous olive oil "fact" that will make you question everything you thought you knew about saturated fat
• Why the popular ultra-processed food classification may be doing more harm than good, and what a Harvard professor says is the real problem ingredient.
• The hidden nutritional crisis quietly unfolding among people on GLP-1 medications
• What industry-funded nutrition research actually looks like, compared to publicly funded studies (the answer may surprise you)
• Rapid fire: the most misunderstood food in America, the one thing Americans obsess over that barely matters, and the health food Dr. Astrup is most skeptical about

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.

In this episode, Holly and Jim break down the science of why anecdotes feel so convincing, and give you a practical framework for turning "my friend lost 30 pounds doing this" into something you can actually use  without falling into the traps that catch almost everyone.

Discussed on the episode:

• The six ways a real, true story can still mislead you, and the scientific terms that explain exactly why
• Why the people who didn't get results are almost never the ones you hear from
• The surprising reason your friend may have lost weight on keto that had nothing to do with keto
• What apple cider vinegar actually does (and doesn't do) for weight loss
• The questions Holly always asks when a patient walks in, swearing by something new
• How to respond when someone you trust is completely convinced that something worked without damaging the relationship
• When you should sit up and pay attention to an anecdote, and when to be suspicious
• The one red flag that should always make you pause before trying something new

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 Jim go beyond the science to tackle the real challenge: knowing exercise helps is one thing, but actually doing it when you're at your lowest is another. They share practical, compassionate strategies for getting off the couch  even when depression is telling you not to.

Discussed on the episode:

• How exercise stacks up against antidepressants (the results will raise your eyebrows)
• Why "moderate" is actually a powerful word when it comes to science
• The reason you can't just tell a depressed person to "go for a walk" and what to say instead
• Why you should need a doctor's note not to exercise
• The surprising truth about whether more intense exercise is actually better for your mood
• Holly's "10-minute rule" - a simple trick for when you truly cannot get off the couch
• What does it mean if you feel like you "need" exercise to feel okay
• The one thing Jim wishes every doctor would bring up when treating depression

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 why. This episode represents a significant shift in perspective that could alter the way you perceive yourself, your struggles, and the people around you.

Whether you've battled your weight your whole life or you've never given it much thought, this conversation will challenge what you think you know  and open the door to something far more useful than judgment.

Discussed on the episode:

• The one word that explains why weight loss advice works for some people and completely fails others
• Why "just eat less and move more" is technically correct and almost entirely unhelpful.
• What a yogurt and an old medication taught Holly about how different bodies really are
• The concept of "food noise" and why some people can't even imagine what it feels like
• Why the number on the scale might be the worst goal you can set
• What the new generation of GLP-1 medications is revealing about biology that we couldn't see before
• How your metabolism is like a thumbprint and what that means for your weight loss strategy
• The uncomfortable truth about why well-meaning advice from lean people often misses the mark

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 exercise, felt guilty for not doing enough, or wondered whether movement even matters now that medications like Ozempic and Wegovy exist, this conversation was made for you.

The answer isn't what you'd expect. Exercise isn't less important in the age of GLP-1s. It's more important just for entirely different reasons.

Discussed on the episode:

• The one word that could completely transform your relationship with exercise
• Why losing muscle during weight loss isn't always the crisis people think it is (but also why you shouldn't ignore it)
• The surprising link between fatigue on GLP-1 medications and physical activity levels
• Why cardio vs. strength training is the wrong question to ask (and what to ask instead)
• The exercise myth Dr. Rogers would delete from the internet forever
• How the timing of your GLP-1 dose might affect when you should work out
• What to focus on after you've hit your goal weight
