Health & Wellness
Health science, reported carefully
Metabolic health, recovery, sleep, hormones, longevity and performance — written for readers who want the evidence, not the hype.

Body Composition
The Lean Mass Question Nobody Asks About Rapid Weight Loss
Scales measure mass, not tissue. When weight falls quickly, some of what leaves is muscle and bone — and the research on preserving it is thinner than the research on losing weight.

Women's Health
Women's Metabolic Health Is Understudied. Read Accordingly.
Hormonal cycles, menopause and pregnancy change metabolic physiology. Most of the research base was not designed to detect those differences.

Sleep
Sleep Debt and the Limits of Recovery Aids

Laboratory Practice
The Injection-Risk Literature Almost Nobody Reads
Contamination, abscesses and bloodstream infection are documented outcomes of non-clinical injection practice. This is the least discussed and best evidenced risk in the entire conversation.
