Nutritional Biochemistry
Macros, micros, microbiome, and the actual evidence base behind every diet trend that crosses your feed. Written from the evidence, not headline science.
Educational journalism, not medical advice. This pillar curates The Beachside Reader's reporting on the subject — general information, not specific to your situation. For health decisions, talk to your own clinician. How we work →
What this pillar covers
The fitness internet is loud about nutrition. The literature is calmer. Most of what works is well-known and unglamorous — adequate protein, real food, distributed intake, calorie balance. Everything else is refinement on top of those four. We cover the refinements seriously without pretending they out-perform the basics.
Subjects threaded through this pillar
- Macronutrient timing
- Protein quality and dose
- Fasting protocols
- Supplements that work
- Microbiome
