Me and my little sidekick over the last 4 Halloweens. Year 2, he was not having any of letting me take a picture with him lol. That was right after he learned to walk, and he basically started running everywhere from that moment on. But I realized something going through these pictures. I’ve been pregnant every single October since 2023, with each of those previous pregnancies ending in first trimester losses. And this October, I’ll be hitting viability with our second little boy🥹 So grateful🙏🏼

@Alexleaf explains why he can't understand the "supplements are a scam" belief, and the marketing trick that lets brands make big claims without ever disclosing the actual dose.

@Alexleaf ran a systematic review on keto and athletic performance. What he found once researchers actually tested elite athletes wasn't what keto's biggest defenders expected.

Part of what makes GLPs so powerful is that they can alter behavior before a person ever reaches conscious contemplation. Many people never meaningfully consider a different way of eating or living because they have never experienced the physiological and psychological conditions that make that alternative feel preferable. GLPs can change the reward landscape first, and cognition often catches up afterward. For some people, cognition never catches up to the behavioral shift, which is why many revert after discontinuation. But that outcome is not inevitable. The period on a GLP can become evidence—>if someone consciously updates the perceived benefits of food, movement, satiety, and their old habits, the new behavior can become genuinely preferable rather than merely pharmacologically easier.
Obesity is driven by a number of interacting factors that all converge to affect its proximal cause: chronic energy surplus. Beliefs, priorities, and preferences are the biggest factors. Most people simply have no desire to be healthy or to put in the effort required to be healthy in the modern environment. And appreciating this truth and the agency that people possess is not mutually exclusive with everything else that follows. Hyperpalatable food supply is next, defined by food options rich in combinations of added sugars, refined grains, added fats, salt, and flavorings. None of these things is obesogenic on its own. Inactivity comes third. People don't want to be active, and the modern environment is great at allowing people to live their lives with very little physical activity being needed. Then you have things like genetics, sleep and circadian disruption, chronic stress, medications, socioeconomic factors, alcohol, toxicants, and the microbiome. Key thing is figuring out what the biggest levers are for a particular person. But energy balance remains king, and encouraging personal agency over behavior is essential (e.g., no food will ever compel you to eat it).

We assume the loudest nutrition claims online are the ones worth listening to. @alexleaf says that's exactly backwards. Alex Leaf on why his own research found keto hurts elite athletic performance, and why saffron holds its own against antidepressants in nine separate studies. Full episode here or on YouTube: DTHshow

No, I'm pretty sure I've addressed this with you already. Even complete fasting for 30 hours reduces LPL activity by just 50% (PMID: 15733074). More amusingly, we have data from a keto RCT that it increases fat cell LPL mRNA content, which is likely an adaptive response to clear excess circulating triglycerides (PMID: 39106867). And I addressed glycerol-3-phosphate in my original post from days ago. Fat cells absolutely do not require high insulin levels or dietary glucose to make it because they can synthesize it from pyruvate, lactate, and amino acids as needed. This pathway exists specifically to allow for re-esterification during times of fasting (PMID: 14641009). And we have tracer studies in humans backing this up beautifully. One showed that a 60-hour fast dropped insulin from 8.8 to 4.3 µIU/mL while simultaneously increasing the rate of fatty acid re-esterification by nearly 3-fold (PMID: 8017334). Please make note that this is below your arbitrary keto threshold for insulin too :-)

The only thing I realized I regretted in my life was not ever having my own child when I was diagnosed with metastatic cancer at 34. There’s a long story around that. I didn’t prioritize career or intentionally put children off. I married young (19), was never on birth control, and the man I married was severely physically abusive, so not having a child with him was ultimately a blessing in disguise. But I also didn’t realize how hard not having a child with my DNA would hit me when I thought my life was ending. I had started dating my husband a short time before my diagnosis, and he singlehandedly restored my faith in men + life. I had my son at nearly 37 and will have my second at nearly 42. Grateful every single day for how my life has turned out.

Likely related to meaning and responsibility. Having people who genuinely depend on you gives work and sacrifice a clearer purpose. Nothing makes you more aware of financial tradeoffs, long term planning, and personal responsibility quite like having a family depending on you. Responsible, invested men are good for families, employers, and society as a whole.

I know that you are approaching this from a place of compassion, but telling people that certain foods "hijack" the brain is facilitating an external locus of control. And this ultimately keeps people stuck because they've now handed over all of their power to the food. This is why addiction literature consistently links external locus of control to worse recovery outcomes and more severe substance use behaviors. There are other ways to address the shame and self-denigration while maintaining a strong sense of personal agency. Now, it is obviously the case that many foods in the modern eating environment are designed to interact with our biology in ways that promote consumption, but acknowledging this truth is a far cry from thinking that these foods "hijack" the brain. The former is simply acknowledging reality, while the latter is turning that normal biological response to eating those types of foods into some mystical power that controls your next bite. There's a greatly underappreciated central importance of one's beliefs when dealing with substance use disorders (and problematic eating behaviors), which ultimately drive their behavior. People are only ever out of control because they believe it so.

Alex somehow finds every animal in need of rescuing lol. He’ll come across some random injured little creature, bring it home, get it settled in a box, and then take it to our local rescue center. This happens at least once a month😭😅

What women often find repellent is not merely that a man lacks confidence, status, height, social competence, or whatever trait he believes would make him desirable. It is what prolonged fixation on that lack can do to his entire personality. Take height. A man may begin with an ordinary insecurity about being shorter than he would prefer, but eventually that insecurity becomes the organizing principle of his mind. Every rejection confirms that women are shallow. Every taller man becomes an enemy. Every female preference is interpreted as cruelty, entitlement, or proof that the world is rigged against him. He becomes defensive before anyone has criticized him… hostile before anyone has rejected him… and resentful toward women he simultaneously expects to desire him. Or take a man who experienced repeated failure with women during the formative years when his sense of desirability was being established. He may spend the rest of his life obsessively pursuing female attention and sexual abundance because he never developed an internal frame of reference in which he felt wanted. He is not merely enjoying women later in life. He is compulsively trying to correct an old deprivation. No amount of attention ever fully satisfies him because the pursuit is not actually about the women in front of him. It is about proving something to the younger version of himself who felt invisible. Eventually, the supposed deficiency is no longer the central problem. The personality that formed around it is. The bitterness, obsessive comparison, self pity, entitlement, passive aggression, and constant need to explain why women are wrong for not choosing him become far more unattractive than the original trait he lacked. He has allowed one perceived disadvantage to consume every more appealing part of his personality. Then he points to women’s reaction to that psychological distortion as proof that his original insecurity was correct. It is a perfectly perfect sealed loop. He believes women reject him because he is short, insufficiently dominant, or not conventionally attractive, while refusing to consider that they may be reacting to the sucking black hole of resentment he has constructed around it. The same is true of the man compulsively collecting women to compensate for not being wanted earlier in life. He interprets his appetite as natural male nature, when it may actually be an old wound demanding constant external proof that he is desirable. The TLDR here is that lacking a desirable trait does not inevitably make someone undesirable. But allowing that lack to deform your character often does.

I was just remembering when my husband and I first started interacting online a decade ago. He had that lethal combination of being brilliant and kind of an asshole, so a lot of people found him intimidating. We met debating a topic too, which feels very on brand. But even while he was disagreeing with me, he was very clearly being nicer to me than he was to everyone else😂 That’s the dream. Not a man who is nice to everyone, but a man who is gentle in one very specific direction.

Yes. Men who are obsessed with a bunch of meaningless casual sex usually aren’t actually obsessed with sex. It’s almost always driven by insecurity and the need for some external checkpoint of validation from women or from their bros. I’ve also seen cases where the man is just terrified of depth and running from himself. But it’s almost never because he’s some true connoisseur of sex. Both are disappointing to me, because either one should be a signal to strengthen oneself. Both are weakness. But alas, they build entire systems around pretending it’s the ultimate peak male experience… when really it just exposes a man with no direction and no real command over himself.
It seems obvious to me that a ton of male anxiety about not having sex is actually about some combination of status anxiety and desire to be loved and not, like, the mechanical act of sex for its own sake.
