What is Lean Fatty Liver or Lean MASH?
"Fatty liver is not always about obesity — it's about metabolism gone wrong."
— Dr. Chetan Kalal
Lean Fatty Liver is the silent liver disease seen in people with normal weight or BMI but abnormal fat deposition in the liver.
It is now called MASH — Metabolic dysfunction-associated Steatohepatitis — the progressive form of fatty liver causing inflammation, fibrosis, and cirrhosis.
Why is Lean Fatty Liver Dangerous?
Looks “healthy” on the outside
Silent progression without symptoms
Delayed diagnosis
Higher risk of liver scarring (fibrosis)
Can lead to cirrhosis, liver cancer
Who is at Risk of Lean MASH?
Normal BMI but:
High sugar/carbohydrate diet
Sedentary lifestyle
Central obesity (belly fat)
Family history of diabetes/liver disease
PCOS in women
Lipid abnormalities
Thin-fat phenotype (common in India)
Symptoms — Often None Early On
Late features:
Fatigue
Indigestion / Bloating
Liver enzyme elevation
Weight gain around belly
Muscle loss (Sarcopenia)
Diagnosis of Lean MASH — Dr. Chetan Kalal's Approach
1. Metabolic Risk Assessment
Fasting sugars, Insulin resistance
Lipid profile, Inflammation markers
2. Liver Fibrosis Screening
FibroScan (Liver stiffness & Fat measurement)
CAP Score for Liver Fat Quantification

Nutrient deficiencies (Vit D, B12)
