Your labs say normal. But you don't feel normal. There's a reason for that… and it's fixable.

Kora MD® pairs you with a real U.S. physician who actually looks at the full picture: hormones, metabolism, inflammation, and everything standard care misses.

You can hire a trainer at a gym, but they don’t see your labs, bloodwork, or hormone levels. You can go to your primary care doc, but they’ll write you a script and say “good luck,” while they move on to the next patient.

Or you could go to Kora MD and get a holistic program with a care coach included that helps you on your entire weight-loss journey.

Mindset & Psychology

The Voices You've Internalized

Every high performer has a mental board of directors.

Not a real one; a psychological one. A collection of voices, standards, and judgments that were installed over decades by parents, coaches, teachers, mentors, and critics. Voices that show up uninvited when you're making a decision, taking a risk, or sitting with uncertainty.

Some of those voices are useful. They represent real wisdom, hard-won lessons, standards worth keeping. They’re the accumulated insight from the coach who taught you discipline, the mentor who pushed you beyond what you thought you were capable of, and the parent who modeled what real commitment looked like.

But some of those voices are noise. Outdated programming from people who meant well but were operating from their own limitations. Criticisms that were more about the critic than about you, or standards instilled by institutions that rewarded compliance over courage.

The problem is that most people have never audited the board.

They carry the voices of everyone who ever had an opinion about them, helpful and harmful together, and run them simultaneously without ever stopping to ask which ones actually belong in the room.

Psychological research on this is consistent: the internal narratives we carry about ourselves, our capability, our worthiness, our likelihood of success, are among the most powerful predictors of performance. Not because they're accurate, but because we act in accordance with them, whether we've examined them or not.

The audit looks like this. When you hear the internal voice that says you're not ready, or you're not qualified, or someone else would do this better, ask where it came from. 

Is it based on evidence from your actual life, or is it borrowed from someone else's fear? Is it a signal worth heeding or a reflex worth overriding?

The highest performers I've observed are not the ones without inner critics. They're the ones who have learned which voices deserve a vote and which ones don't.

Your internal board of directors should be staffed by people who actually belong there.

Audit the room.

Walking Can Reduce Alzheimer's Risk, But It Depends on Your Genes

New research following nearly 3,000 adults across 10 years found that regular walking may help slow age-related cognitive decline, particularly in people at higher genetic risk for Alzheimer's disease, but that the protective benefit differs meaningfully between males and females, suggesting that a one-size-fits-all approach to brain health may be missing the mark.

Why it matters: Exercise protects the brain, but the degree of protection depends on individual biology. High performers who are serious about long-term cognitive function need to understand their own risk profile, not just follow generic advice.

The Supplement You're Already Using Wrong

Most people who take creatine think of it as a muscle supplement.

They're not wrong. Creatine is one of the most well-researched performance compounds in existence, with decades of clinical evidence supporting its role in increasing strength, power output, and muscle mass. If you lift weights and you're not taking creatine, you're leaving a meaningful edge on the table.

But a major new scientific review published this week is making the case that the conversation about creatine has been focused entirely on the wrong organ.

A comprehensive review published in the Handbook of Creatine and Creatinine In Vivo Kinetics, drawing on decades of clinical and laboratory data, found that creatine reaches the brain in measurable quantities. People with naturally lower baseline levels, including older adults, vegetarians, and vegans, show improvements in memory, mood stability, and cognitive processing speed after supplementation. 

The mechanism makes sense when you understand what creatine actually does. It powers ATP regeneration, the process by which your cells produce usable energy. That process matters in muscle tissue, yes. But it matters just as much in the brain, which is one of the most energy-intensive organs in the body and runs on the same cellular fuel system.

Researchers are now exploring creatine's potential role in slowing muscle and bone loss during menopause, managing depression through its influence on brain energy metabolism, and possibly slowing the progression of Parkinson's disease, a set of applications that has nothing to do with how much weight you can move.

For the high performers reading this, the practical implications are straightforward. If you're already taking creatine for performance, you may be getting cognitive benefits you didn't know to look for. If you're not taking it, particularly if you're a vegetarian, a woman in perimenopause, or someone over 45, the evidence for starting is stronger than most people realize.

Five grams a day. It's one of the few supplements with decades of safety data and a genuinely expanding body of evidence pointing in the same direction.

The gym benefit was always real. The brain benefit is just catching up.

Ozempic Works Dramatically Better for Some People

A year-long study found that people taking GLP-1 drugs like Ozempic may be getting dramatically better results depending on why they overeat in the first place, with emotional or reward-driven eating responding far more strongly to the medication than hunger-driven eating.

Why it matters: GLP-1 drugs are reshaping metabolic health conversations. Understanding that they work differently based on the underlying driver of overeating is a meaningful insight for anyone exploring these protocols or advising others who are.

Personal Finance Tip of the Week

The Wealth Gap Nobody Talks About

There's a financial divide in America that doesn't get nearly enough attention, and it's not the one you usually hear about.

It's the retirement gap.

Roughly 56 million Americans lack access to an employer-sponsored retirement plan at work, according to 2025 research from the Pew Charitable Trusts. These are people who go to work every day, earn a paycheck, and have no simple, tax-advantaged, employer-supported mechanism for building long-term wealth. PR Newswire

For the high performers reading this newsletter, that number might feel abstract. Most of you have access to a 401(k) or equivalent. Some of you have multiple vehicles. The infrastructure is there.

But here's what that gap reveals that is directly relevant to you: the single biggest driver of retirement wealth isn't investment performance, it isn't market timing, and it isn't picking the right stocks.

It's consistent participation over time.

Morningstar research found that workers with ten or more years of sustained participation in retirement plans could see 67% to 125% higher retirement wealth, with consistent savings behavior identified as the biggest determinant of growing a nest egg. 

Read that again. It’s not returns, not allocation, but consistency over time.

This is the most unsexy insight in personal finance, and it's the most important one. The gap between people who build meaningful wealth and people who earn meaningful income but don't build wealth almost always comes down to the same thing: the disciplined, boring, sustained practice of putting money in, month after month, year after year, regardless of what the market is doing or how the business quarter went.

The high earner who contributes inconsistently to retirement accounts will lose to the moderate earner who contributes consistently every single time, given enough years. The math is undefeated.

If you're not maxing your available retirement vehicles, 401(k), IRA, SEP-IRA, defined benefit plan, there is no optimization above that level that matters more. Start there, stay there, and let time do the rest.

VCs Are Now Funding the Business Model They Used to Hate 

For decades, venture capitalists dismissed agencies as "lifestyle businesses" too reliant on headcount to ever scale like software. Now, with AI compressing the relationship between revenue and staff, the biggest VC firms are racing to fund them.

Why it matters: This isn't just a VC story. For any founder running a service-based business, whether it’s consulting, marketing, coaching, or recruiting, AI is changing what your business can look like structurally. The margin profile that made these businesses uninvestable is shifting fast.

The Price of Playing It Safe

There's a version of business caution that looks like wisdom from the outside.

The leader who waits for more data before making a call. 

The founder who needs more certainty before committing to a direction. 

The operator who keeps the strategy deliberately ambiguous because they don't want to be wrong.

From the inside, it feels like prudence. From the outside, and more importantly, from the competitive landscape, it looks like paralysis.

The cost of indecision is one of the least visible costs in business. Bad decisions show up on the P&L. They generate feedback and create pressure to course-correct. 

Slow decisions, non-decisions, and perpetually deferred calls are invisible. The team adjusts to the ambiguity, the market keeps moving, and the window closes quietly.

Here's what I've watched happen in high-performing organizations versus stagnant ones: the high-performing ones have a culture of rapid, reversible decisions. Leaders at every level are empowered to make calls within their domain, accept that some will be wrong, and course-correct quickly. The iteration cycle is fast because the decision cycle is fast.

Stagnant organizations do the opposite. They route every significant call through the same narrow set of decision-makers. They build consensus before moving. They wait for information that never arrives in the form they're hoping for. And by the time they decide, the opportunity they were evaluating has shifted.

Jeff Bezos captured this well with his "Type 1 versus Type 2 decision" framework. Type 1 decisions are irreversible and consequential, and they warrant real deliberation. Type 2 decisions are reversible and recoverable; most business decisions fall in this category, and they should be made quickly by the person closest to the situation.

The error most organizations make is treating Type 2 decisions like Type 1.

The practical fix is simple but uncomfortable: set a decision timeline. If a call needs to be made, define when it will be made and who will make it. Stop the cycle of "let's revisit this next week" that produces no new information and burns two more weeks. Train your team to bring you options with a recommendation, not open-ended problems.

Speed of decision is speed of learning. Speed of learning is a competitive advantage.

The safest thing you can do in business is decide and move.

Anthropic Just Made Its Biggest Move Into Wall Street

Anthropic launched a suite of pre-built AI agents for major banks and debuted its most capable financial services model yet. They separately announced a $1.5 billion joint venture with Blackstone, Hellman & Friedman, and Goldman Sachs to create an AI-native enterprise services firm that puts Claude at the core of how mid-sized companies actually operate.

Why it matters: When the world's largest private equity firms co-invest $1.5 billion to embed AI directly into company operations, that's not a tech story; it's a business infrastructure story. The operators who understand what AI-native operations look like in practice will have a compounding advantage over those still thinking of AI as a productivity tool.
