How ketosis, fasting, and mood profiling drive peak mental performance

Executive overview

Sustained single-tasking for four hours is an elite capability most people can't access. Nutritional ketosis, combined with intermittent fasting and timed exercise, is a practical protocol for achieving it without stimulants.

Understanding your innate affect profile — the baseline intensity of your positive and negative emotions — is the starting point for effective mood management. Protocol design must follow from self-knowledge, not the other way around.

The protocol is in service of life. Life is not in service of the protocol.

Morning routine and ketosis transition

• Net carbs kept under 10g/day to enter ketosis fast, especially when already adapted to intermittent fasting
• Waking routine: cacao with cacao butter (under 3g net carbs), 10-minute meditation in hot tub, cold pool dip, cold shower
• Exogenous ketones (BHB + 1,3-butanediol) used only during the 4-day transition window — not chronically, due to potential liver toxicity
• Nitro cold brew taken ~15 minutes before demanding cognitive work
• Intermittent fasting window of 16–18 hours depletes liver glycogen; adding morning zone two cardio accelerates the shift

Exercise timing and ketosis

• Weight training scheduled late afternoon to avoid compounding morning cortisol spikes with glucose spikes from resistance work
• Zone two cardio done fasted in the morning — ideal for glycogen depletion without disrupting ketosis entry
• High-intensity or resistance training can spike glucose enough to stall ketosis transition
• Cyclical ketogenic diet (CKD) — used historically for weight cutting while maintaining muscle — now considered too complex to maintain

Ketosis for mood and cognition

• Ketosis described as comparable to modafinil for cognitive clarity, but without the long-term penalties
• Consistently removes the bottom 50% of negative affect and raises positive baseline by approximately 20%
• Outperforms SSRIs for mood stabilization in personal experience — no peaks and troughs
• Fasted morning exercise is highly effective for reducing negative affect without suppressing positive affect

The four affect profiles

• Mad scientist: high positive, high negative intensity — big highs and low lows
• Cheerleader: high positive, low negative — happiest baseline, but tends to avoid hard feedback
• Judge: low positive, low negative — flat, steady, suited to high-stakes procedural roles
• Poet: low positive, high negative — most creative and romantic; prone to rumination and depressive episodes

The poet's ruminative tendency shares neural circuitry (ventrolateral prefrontal cortex) with creative work and falling in love — which links depressiveness, creativity, and romanticism in the same profile.

Applying mood management

• Identify your affect profile first — it determines which direction you need to manage
• Goal is not to eliminate negative emotion (it serves protective functions) but to prevent dysregulation
• For mad scientists and poets: ketosis, fasted exercise, and controlled caffeine timing are particularly effective
• Treat personal health as a lab: scientific information first, then experimentation, then protocol refinement
