The Human Upgrade: Biohacking for Longevity & Performance
Sulfur Amino Acid Restriction Effects
Dave summarizes research where methionine/cysteine restriction triggers FGF21, fat browning, and thermogenesis.
This week’s stories:
Healthy Diets That Offset "Bad Genes"
A major UK Biobank study of over 100,000 people found that following any one of five healthy dietary patterns was associated with up to 3 extra years of life — and the benefit held regardless of genetic predisposition to longevity. Your DNA is not an excuse. The macro pattern matters more than the perfect protocol.

Micro-Habits in Sleep, Activity, and Diet That Extend Life
Researchers built a composite "SPAN" score combining sleep, movement, sedentary time, and diet quality and found that small improvements across all four — we're talking minutes per day — cut mortality risk by up to 64% when stacked together. The gains only showed up when behaviors improved in combination, not in isolation.

Methionine and Cysteine Restriction: The Diet That Mimics Cold Exposure
New research shows that reducing sulfur amino acids — methionine and cysteine, found heavily in certain animal proteins — triggers fat browning and thermogenesis in mice, mimicking the metabolic effects of cold exposure without the cold. Supporting human data from Nature Metabolism suggests this lever works in people too

Tyrosine and Lifespan: What the Data Says for Men
A Mendelian randomization analysis of over 270,000 UK Biobank participants found that genetically higher tyrosine levels were associated with nearly one year shorter lifespan in men — with no significant effect in women. This reflects lifelong endogenous levels, not short-term supplementation, but it's a signal worth understanding if you're using tyrosine strategically

War Doomscrolling and WW3 Anxiety as a Stealth Aging Accelerator
Compulsive consumption of conflict and war news is linked to PTSD-like symptoms, existential anxiety, and chronic stress — even in civilians far from any battlefield. Layered on top of cardiology data connecting chronic stress to heart disease and stroke, your news diet is now a legitimate healthspan variable. Subtractive biohacking is still biohacking.
