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

3. Nutritional Assessment

• Sarcopenia check (Muscle mass loss)

• Nutrient deficiencies (Vit D, B12)

Treatment Strategy for Lean MASH

"It's not about weight loss alone — it's about correcting metabolism."
— Dr. Chetan Kalal

1. Precision Nutrition

• Low Glycemic Load Diet
