Dan Harris: Tim Ferriss, it's great to have you back on the show.

Tim Ferriss: Thanks so much. It's wonderful to be here again and to see you.

Dan Harris: The feeling is mutual. Let me start with what might seem like a very basic question, though it could carry hidden layers of depth—I'm never quite sure if it's more complex or straightforward than it appears. Essentially, how are you holding up these days? You've been quite open about some challenging personal experiences lately, and I'm genuinely interested in your current state.

Tim Ferriss: That's a question that appears simple on the surface but holds considerable nuance. Fortunately, my response is direct and positive: I'm doing better than ever before. I feel truly excellent across the board. If you'd like, we can explore the reasons behind this, but for now, I'll keep it concise—I'm thriving mentally, physically, emotionally, and in every other dimension. Optimism abounds, and I'm feeling robust and holistic in my well-being. Feel free to steer the conversation wherever you'd like.

Dan Harris: That's music to my ears, sincerely. I'd love to hear more about what has led you to this place of peak condition.

Tim Ferriss: Absolutely, several key factors have contributed. One major pitfall in the realm of personal growth—or self-improvement in general—is the risk of slipping into self-absorption or excessive focus on oneself.

Dan Harris: Absolutely true.

Tim Ferriss: The antidote to that tendency is straightforward: prioritizing relationships. As a species, we're wired for social connection, and isolation—whether physical or mental—tends to amplify issues like instability, obsessive-compulsive tendencies, depression, anxiety, or any number of mental health challenges. I've maintained and intensified practices from our last conversation, such as conducting an annual review of the previous year to identify my most vital, uplifting relationships—those that energize rather than drain me. Then, I schedule dedicated time blocks throughout the upcoming year for meaningful interactions with them. The length varies based on life circumstances; for me, it ranges from extended weekends to full weeks, like five days in Montana's wilderness with lifelong friends.

While I don't dismiss therapy—it's valuable—endlessly discussing problems doesn't always resolve them if talk alone were sufficient, it would have by now. Therapy has its role, but it's not the sole solution. Simply being in the company of fun, flawed, wonderful friends—sharing laughs over wine, meals, or campfires—provides profound relief. That's one cornerstone. Another is consistent meditation, typically twice a day for 10 minutes each session, keeping it simple and reliable.

Venturing into more advanced territory, there's accelerated transcranial magnetic stimulation, or TMS. This brain stimulation technique has been around for decades, but recent advancements in hardware and software—especially over the past five years—have transformed it. Pioneers like Nolan Williams from Stanford, who unfortunately passed away recently, have driven much of this progress.

Traditional TMS might span months, involving a device placed against the head that generates magnetic fields to excite or inhibit specific brain circuits. It's used for depression, neurodegenerative conditions, anxiety, OCD, and more, depending on the targeted areas. Accelerated TMS condenses months of treatment into one week: sessions every hour, 10 times a day, each lasting a few minutes of pulses followed by 50-minute breaks.

One protocol, developed at Stanford and known as SAINT—though they've stepped back from that name—has shown 70-80% depression remission rates in many cases, with lasting effects. Patients often follow a five-day course, then boosters every few months. I've experimented with this multiple times over recent years. My first round produced near-miraculous outcomes.

I entered with moderate-to-severe OCD, officially diagnosed, characterized by relentless ruminative loops—not rituals like light-switching, but inescapable mental cycles over grudges, fears, plans, or conversations. These loops disrupt sleep, breed fatigue, erode resilience, and cascade into depression. My anxiety-rumination-depression sequence was at 7-8 out of 10 severity, profoundly impacting life. Post-five-day treatment, effects emerged after a 2-3 week delay—no clear scientific explanation yet—and suddenly, anxiety and rumination dropped to zero for 3-4 months. Nothing, not even psychedelics I've extensively explored and supported research on, matched this.

Subsequent boosters failed, dashing hopes for a reliable tool. Recently, in a desperate final attempt in Northern California, I tried a single day of accelerated TMS, pre-dosed with D-cycloserine (DCS), an old antibiotic for tuberculosis or UTIs that enhances neuroplasticity via NMDA receptors (whether as partial antagonist or agonist isn't crucial here). This combo sometimes outperforms months of older protocols. The switch flipped the next day, and 2-3 months later, it's held. Caveat: results vary, but early data suggests strong efficacy for anxiety and OCD alongside depression. It's transformative—a entirely new existence.

Layered with fundamentals like exercise, nutrition, and sleep, plus intermittent ketosis—which I'm in now—these elements synergize powerfully. Ketogenic approaches, per metabolic psychiatry research from Harvard's Chris Palmer and others, excel where meds fall short for mental health. That covers the highlights.

Dan Harris: Rest assured, detailed responses are always welcome here—us podcasters thrive on them. Erase any hesitation.

Tim Ferriss: Noted.

Dan Harris: So many follow-ups. High-level, 'a different life' resonates deeply and brings me joy.

Tim Ferriss: Thanks, Dan. The gulf between constant 8/10 monkey-mind anxiety fixation and 1-2/10 calm is vast—two distinct realities.

Dan Harris: You referenced transcranial magnetic stimulation—TMS?

Tim Ferriss: Yes, magnetic stimulation.

Dan Harris: I'll note the conversation with Nolan Williams for listeners, understanding you're the experimenter, not the expert. More on availability for everyday people and evidence strength?

Tim Ferriss: Disclaimer: I'm not a doctor. TMS has decades of data across uses. Accelerated TMS shows compelling evidence; pairing with DCS is cutting-edge, risky territory—I opted in due to desperation. I'm among perhaps 60 OCD/anxiety patients treated this way at my clinic.

Hardware leaders I've used: BrainsWay and MagVenture—both effective for some. Beware unethical providers straying from protocols. Accelerated TMS exists in major cities like New York, California, Chicago—not insurance-covered like standard TMS, due to intensity (week off work, 10 hours/day). DCS pre-dosing could slash time to one day, easing logistics and costs, broadening access. Promising, though scaling data needed.

Dan Harris: You highlighted relationships transforming life, mirroring my shift from workaholic isolation to prioritizing connections—huge mental health boost. Do an annual plan for cup-fillers. Did you endure similar neglect?

Tim Ferriss: Definitely, for varied reasons. Hindsight clarifies: balance compulsive socializing (avoiding self) versus isolation. I favored isolation—workaholism made me feel productive alone, possibly valid. Also, an unspoken self-help trap: perfect yourself first via endless 'work,' delaying real engagement—like mastering soccer theory solo before playing. You simulate life, fixating recursively on self-improvement, never truly participating. Aging or wisdom shifted me: pair bleeding-edge pursuits with timeless basics. Evolutionary biology underscores social needs—lacking contact mimics caged animal distress: anxiety, depression surge. Relationships are foundational.

Dan Harris: Preach.

Ahead: Tim on self-optimization risks, true priorities, keto benefits, AI for health queries, and beyond.

This ties to your self-help essay—'optimizer' from 4-Hour Workweek fame. Your stance on optimization now?

Tim Ferriss: I target specific levers thoughtfully. Key evolution: habitually ask, 'What am I optimizing for? Why?' Social media tempts unexamined pursuits (greed, vanity). 4-Hour Workweek critiques work/money chases.

Family Alzheimer's (APOE 3/3 cases; I'm 3/4) spurs cardiac/neuroprotective efforts—like periodic ketosis (2-3x/year). Mechanisms: neuroprotection, anti-cancer potential (see Dominic D’Agostino interviews). Low-risk, ancient metabolic tool versus unproven long-term GLP-1s.

Intermittent fasting transformed my insulin sensitivity (family prediabetes risk): 8-hour window (e.g., 2-8pm). Time-restricted eating aligns naturally.
