Your Diet Sucks

Support the show at Patreon.com/yourdietsucks
There is no plastic spoon in your brain (unless you put one there). There is no credit card in your diet. We regret to inform you that this does not mean everything is fine.
Both of those numbers came from real studies, and both got mangled somewhere between the paper and your feed. Kylee walks through what actually survives scrutiny, where the fertility conversation outruns its evidence, and why the BPA-free sticker on your Nalgene is not the reassurance you think it is.
Zoë traces the whole mess from exploding celluloid billiard balls to Life magazine throwing a party for disposability in 1955. We get into why humans are catastrophically bad at judging exactly this kind of risk, how much you should actually be thinking about it, and the one exposure source that matters more than anything in your kitchen drawer.
Nobody needs to panic about their hydration strategy. Maybe buy new spatulas. Definitely don't buy the $300 filter from the guy who could be regulating this instead.

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."

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).

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.

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?
