The Protocol:

⏱️ When: Get bright light within 30 minutes of waking, then track your energy peaks throughout the day for 7-10 days
🎯 Specificity: Use a circadian rhythm tracking app to identify your peak performance windows—schedule deep work, important decisions, and complex problem-solving during these times (typically 2-4 hours after waking for morning types, late afternoon for evening types)
🚫 Friction removal: Set automatic sunrise alarm, link light exposure to morning coffee routine, block your calendar for high-cognitive tasks during your identified peak hours
📊 Tracking: Monitor your daily energy curve and optimal timing for focus work, meetings, and creative tasks; track circadian alignment and sleep consistency
💰 Reward: 20-40% improvement in cognitive performance on complex tasks, better decision-making quality, reduced errors within 2-3 weeks of circadian-aligned scheduling

Light Therapy Lamp Recommendations

Discussion: A member asked for sunlight lamp recommendations available in Germany.

The verdict: Multiple experienced community members who conducted extensive research 1-2 years ago independently reached the same conclusion: the Beurer TL 100 is the optimal choice. It delivers 10,000 lux at usable distance (25cm), features sun-like LEDs with complete wavelength spectrum, holds medical device certification, and provides 6,000K color temperature.

Consider this: When selecting a light therapy lamp, prioritize spectrum quality (sun-like LEDs) and verified lux output over brand names or influencer endorsements. The critical specs are: 10,000 lux at 25cm distance, sun-like LED spectrum, medical product certification if possible, and color temperature around 6,000K.

Cutting Board Materials - Wood vs. Titanium

Discussion: A member asked for recommendations on kitchen cutting boards, wanting to avoid plastics but unsure about the best alternative between wood, titanium, and other materials.

The verdict: Wood is the optimal choice, specifically end-grain (or “headwood”) construction where the grain runs vertically rather than horizontally. This orientation means your knife cuts between the fibers rather than through them, making the board virtually indestructible and self-healing. Wood naturally possesses antibacterial and antifungal properties, eliminating concerns about bacterial growth that often drive people toward synthetic materials. Maintenance is minimal—simply rub in MCT oil once a year to preserve the wood.

Consider this: When selecting a cutting board, search for “end-grain cutting board” or “headwood cutting board” to find quality options. The vertical grain orientation is the key differentiator that provides longevity and hygiene benefits without the microplastic concerns of synthetic alternatives or the impracticality of metal surfaces that dull knives quickly.

Fasting Protocols - What Works in Practice

Discussion: Karol shared results from a 5-day Fasting Mimicking Diet (FMD) experiment and asked the community about their experiences with various fasting approaches: 16:8, OMAD, water fasts, and fasting-mimicking diets.

The verdict: Multiple experienced fasters shared their protocols. Several prefer water fasting over FMD, finding it psychologically easier not to eat at all. The typical approach: 3-5 day water fasts 2x per year, with 16:8 as a daily baseline (chosen for lifestyle fit rather than perceived magic). One practitioner uses 1-3 tablespoons of exogenous ketones during fasts, though others cautioned this may interfere with autophagy—the safe approach is water and unsweetened tea only. Regarding lean mass concerns: Peter Attia reportedly stopped quarterly 5-day water fasts due to muscle loss. The 3-day (84-hour) protocol appears to preserve lean mass better, with practitioners reporting stable strength metrics and scale weight pre/post fast, though DEXA confirmation is pending.

Consider this: You can enhance autophagy benefits and potentially shorten fasting duration by combining strategic interventions: sauna sessions, coffee, EGCG supplementation, high-intensity training, resveratrol, and quercetin. This stacking approach may deliver similar benefits with reduced fasting time and lower muscle loss risk.
