    Why is Everyone Using Peptides?

    BPC-157. TB-500. MOTs-C. If those sound like droids from a Star Wars spinoff, congratulations on your healthy relationship with the internet. For everyone else: peptides are the injectable wellness trend that jumped from bodybuilding forums to med spas to your feed, promoted for healing, muscle, fat loss, and living forever. But what does the science say, and what are peptides, actually? Some of them became legitimate blockbuster drugs: insulin is a peptide, and so are the GLP-1s. But the ones flooding your feed never went through human trials. They went from lab animal studies straight to "research chemical" websites, and from there to longevity clinics charging four figures for injections of compounds nobody has proven do anything in people. This week, Zoë traces how we got from insulin to Instagram: the bodybuilding underground, the anti-aging clinics, and the influencer economy that turned unproven injectables into a billion-dollar category. Kylee breaks down what the research actually shows for the big-name peptides, why "thousands of patients swear by it" is not evidence, and what she tells athletes who ask whether BPC-157 will fix their tendons faster. Plus: what to know about anything sold in a vial labeled "for research purposes only." rabbit: our title sponsor and the run apparel we actually wear.

    July Bonus: How to Talk to Friends About Food, Can Undereating Cause Weight Gain, Blood Sugar Myths, and What to Actually Eat

    Join our Patreon here for even more bonus content: https://www.patreon.com/YourDietSucks You can submit questions for our next bonus episode here:https://docs.google.com/forms/d/e/1FAIpQLSdEp0TXOPsUUaJcK45LZjVPKIeMEIwRkW4i8ArsIDTIAO6uEg/viewform It's July, we're alive, and we're surrounded by wildfire smoke, so naturally we're answering your questions. We get into: How to talk to a friend when you're worried about their relationship with food. What's actually concerning, what's projection, and what's none of your business? Can you be consistently underfueling and still gaining weight? The answer has layers, and most of them aren't on the scale. Does the order you eat your food in actually change your blood sugar? Or is meal sequencing, as one listener put it, "anti-sandwich propaganda"? And nutrition periodization vs. nutrition timing: what these actually mean in practice, why the recovery window isn't a slamming door, and yes, you're allowed to eat before bed. Thanks for being here. Your support is literally what keeps this show going. Got a question for next month?

    The Keto Diet

    Support us on Patreon! Keto promised something no other diet could: cut the carbs, flip a metabolic switch, and burn fat without counting a single calorie. A magic loophole in human physiology. So does it actually work? This week we trace keto from a deaf Victorian undertaker who accidentally invented the first diet book, to a 1920s epilepsy clinic that turned fasting into medicine, to the bankrupt Atkins empire, to the shirtless guys on TikTok insisting grains ruined their lives. Then we get into the science: what ketosis actually is, why the carb-insulin hypothesis doesn't survive a metabolic ward, what Kevin Hall's lockdown studies really found, and why you should treat "it worked for me" with a grain of ketogenic salt. We also get specific about athletes: what fat adaptation can and can't do and who might genuinely benefit from a low-carb approach versus who's just going to get slower and crankier (Zoë, for sure). rabbit: 10% off with code SUMMERSNACKS10 at runinrabbit.comTailwind Nutrition: 20% off with code YOURDIET20 at tailwindnutrition.comOsmia Skincare: 20% off with code YDS20 at osmiaskincare.comMicrocosm Coaching: work with a real human coach at every level at microcosm-coaching.com

    Are Seed Oils Actually Bad For You?

    Join our Patreon! This is the most requested episode in two years, and the one strangers corner Zoë about the second they find out she hosts a nutrition podcast. Seed oils. Did they secretly poison the country, or did the internet just find a new villain with a great backstory? We go claim by claim through the anti-seed-oil case. The omega-6 inflammation pathway. The omega-6 to omega-3 ratio, which turns out to matter more for some people than the internet's loudest voices would ever admit. Oxidation when you heat polyunsaturated fat. And the chart that maps seed oil consumption onto every chronic disease in America. Zoë and Kylee dive into how a cooking fat became a one-word loyalty test that Mobile, Alabama and Marin County somehow agree on. RFK Jr. is out there RFK-ing the fries. Sweetgreen ran a seed-oil-free menu. And every influencer swearing canola oil is killing you has a thirty-dollar meat stick to sell you. rabbit: Our title sponsor, and the kit we actually run in.

    June Bonus: What Cravings Mean, Magnesium Supplementation, Set Point Theory, DIY Electrolyte Mix and "Looking Like a Runner"

    This week, Kylee and Zoë are back on the couch, and in video! We're diving into our recent adventures, then tackling what happens when set point theory meets an industrial food system. We also unpack the science of cravings and what it means if you're craving specific foods. We also get into who might need to supplement with magnesium, and how you to make your own electrolyte mix - and when it might be easiest to just buy mix. We also talk about the idea of "looking like a runner," and cultural discussions of body image can hold people back. We chat about our own experiences with this idea, how we've both navigated those thoughts in our careers, and how Kylee works with clients to address body image issues so they can fuel better and thrive.

    Why Am I So Hungry?

    You were taught that hunger is a trick question. Before you're allowed to eat, you have to clear the suspects: you're bored, you're thirsty, you're emotional, you're just not disciplined enough. Somewhere at the bottom of that list, if it makes the list at all, sits the radical possibility that you might simply need food. This episode is about where that interrogation came from and why most of it is nonsense. Hunger isn't one thing. It's three or four separate biological systems wearing a single word, and the cultural reflex to distrust all of them runs about 800 years deep. We go from fasting saints starving themselves toward God, to a Columbia psychologist in the 1960s who built a whole career on the idea that some people's hunger was simply broken. The belief refused to die, and you can still hear it in every diet app, every set of smaller plates, every stranger telling you to drink more water and wait for the feeling to pass. Plus why some of us really do run hungrier than the people around us, and what quietly moves the signal. By the end, the question stops being "am I actually hungry" and turns into something more useful: who convinced you that you shouldn't be?

    Are Artificial Sweeteners Actually Bad For You?

    In 1879, a chemist named Constantin Fahlberg sat down to dinner without washing his hands after a day spent handling coal tar. His bread tasted strangely sweet. So he went back to the lab and started tasting everything on his bench until he found the source. That was saccharin, the first artificial sweetener, discovered because a man would not wash his hands before dinner. Nearly 150 years later, we are still arguing about whether the stuff is going to kill us. This week, Zoë and Kylee dig into the question every diet-soda lover has had to defend at a gas station: are artificial sweeteners actually bad for you? They trace how a coal-tar accident became a billion-dollar industry, why the WHO's "possibly carcinogenic" label on aspartame puts it in the same risk tier as pickled vegetables and working as a carpenter, and how Donald Rumsfeld personally muscled aspartame through the FDA. The saccharin cancer scare that haunted a generation came from male rats dosed with the equivalent of hundreds of sodas a day, through a mechanism human bodies do not even have. Along the way: the wartime rationing that built the sweetener industry, the cyclamate the US banned and never reinstated while the rest of the world kept drinking it, the every-fifteen-years villain cycle that has run through fat, high-fructose corn syrup, gluten, and seed oils, the genuinely fascinating Suez microbiome research where scientists grew human gut bacteria in mice, the stevia-in-a-petri-dish problem, and the erythritol heart-attack headline that fell apart the moment anyone read the study. Plus: why these things were always sold to women as a permission structure, the one category athletes actually need to watch (sugar alcohols, and the osmotic chaos they bring to a long run), the client drinking ten Liquid IVs a day, and a hot-takes round that settles Diet Coke versus Coke Zero once and for all.

    Should You Count Calories? The Wild History and Questionable Science Behind Calorie Counting

    Should you count calories? A century ago, a Los Angeles doctor named Lulu Hunt Peters sold two million copies of a book that taught American women to count calories as a patriotic duty during WWI. She invented the 100-calorie snack pack. She set the 1,200-calorie floor that still haunts diet apps in 2026. The framework she popularized is still running your relationship with food. This week, Zoë and Kylee dig into the question every active person has wondered about: should you be counting calories? They trace how a unit of heat invented to measure factory worker rations became the dominant logic of American eating. Where the 2,000-calorie label on every food package actually came from (it isn't science, it's a 1990 design choice). Why calorie counting is legally allowed to be 20 percent wrong before it ever reaches your plate. And why a framework with this many cracks has held on for a hundred years. Along the way: what calorie counting did to the American food supply during the low-fat era, what the Biggest Loser metabolic adaptation research actually showed, why even registered dietitians can't accurately track their own intake, what set point theory says about why restriction backfires, and whether calorie tracking apps are tools, traps, or both. For athletes, the questions that actually matter for performance, and what the research says about who calorie counting helps and who it harms. Plus: the early feminist origins of dieting (yes, really), why your microbiome is doing math your app can't see, and why this number keeps its grip on us even when the science says it shouldn't.
