The evidence, written plainly.
Short pieces on the studies behind each rule in the plan, and on the claims the category makes that the evidence doesn't support. Every number carries a named source.
Testosterone: what a normal number is at 35, 45, and 55
The honest reference range is three and a half times wider than any clinic ad admits — and age moves the number far less than weight does. What the reference studies actually found.
Blood pressure: the first number that drifts
Nearly a third of men under 40 already sit above the line, and most haven't felt a thing. What the two numbers mean, why one office reading is noise, and what training measurably does.
Ferritin: what it is, and what the number reflects
The storage form of iron, the lab value that stands in for it, and why tired lifters keep hearing about it. Plain numbers, no panic.
ApoB: the particle count your cholesterol panel hides
LDL tells you how much cargo. ApoB counts the trucks. Why lipid researchers keep saying the truck count is the number that matters.
hs-CRP: the inflammation number, explained
One protein, one number, and a surprisingly honest read on how calm your system is running. What the categories mean and what moves them.
HbA1c: your three-month sugar average
One number that summarizes ninety days of blood sugar — no fasting required. What it is, why it beats a single glucose reading, and what moves it.
Vitamin D: what the 25-hydroxy number means
The sunlight hormone, the blood test that stands in for it, and an honest read of a hyped literature. Plain numbers, both directions.
