WHAT IT MEASURES
ALT lives mostly in liver cells. When those cells are stressed or damaged, more of it shows up in your blood.
WHY IT MATTERS
Mildly high ALT is often the first sign of fatty liver, which affects one in four adults and is reversible.
WHEN TO RETEST
Every six months, and avoid hard workouts two days before.
WHAT MOVES IT
Five levers, ranked.
Based on clinical evidence. Your clinician picks the ones that fit you.
Less alcohol
The liver recovers fast when you cut back.
Fewer added sugars
Fructose is processed by the liver.
Lose waist fat
Even 5% weight loss lowers ALT.
Daily movement
Activity clears liver fat.
Coffee
Two cups a day is linked to lower ALT.
