What Is Fatty Liver Disease?
Fatty liver disease — now officially termed MASLD (Metabolic-Associated Steatotic Liver Disease), previously called NAFLD — is the accumulation of excess fat in liver cells in people who drink little or no alcohol. When more than 5% of the liver's weight is fat, it is classified as fatty liver.
MASLD is not a single condition. It is a spectrum — from simple, harmless fat accumulation to active inflammation (MASH, formerly NASH) that causes liver damage, fibrosis, cirrhosis, and eventually liver cancer. The trajectory depends on metabolic factors you can control.
The 4 Grades of Fatty Liver
What Causes Fatty Liver?
MASLD is a metabolic condition deeply linked to how your body handles fat and sugar. Key risk factors include:
- Obesity and central adiposity: Waist circumference >90 cm (men) / >80 cm (women) in Indians significantly increases risk
- Type 2 diabetes / insulin resistance: The liver receives excess glucose it cannot process, storing it as fat
- Dyslipidaemia: High triglycerides or low HDL cholesterol
- High-fructose diet: Sugary drinks, sweets, processed foods
- Sedentary lifestyle
- Hypothyroidism, PCOS: Hormonal conditions that promote fat storage
- Genetics: The PNPLA3 gene variant is more prevalent in South Asians and increases MASLD risk
Important: Normal weight does not exclude fatty liver
India has a high prevalence of "Lean MASLD" — fatty liver in people with a normal BMI. Abdominal fat, insulin resistance, and genetics matter more than weight alone.
What to Eat — and What to Avoid
Liver-Friendly Foods
- Vegetables — especially leafy greens, broccoli, carrots
- Fruits (in moderation — avoid fruit juices)
- Whole grains — brown rice, oats, millets
- Legumes — lentils, chickpeas, rajma
- Fish and lean poultry
- Nuts in moderation (walnuts, almonds)
- Coffee — 2–3 cups/day shown to reduce liver fat
- Olive oil and cold-pressed coconut oil
Foods to Avoid
- Sugar — sweets, biscuits, mithai
- Sugary drinks — cold drinks, juices, flavoured milk
- White rice, maida, white bread
- Fried and deep-fried snacks
- Red meat — especially processed meat
- Alcohol — any amount worsens MASLD
- Packaged and ultra-processed foods
- Full-fat dairy in large quantities
Exercise: The Most Powerful Treatment
Exercise is the single most effective intervention for fatty liver — even without weight loss. Studies show that 150 minutes of moderate aerobic exercise per week reduces liver fat significantly within 8–12 weeks.
- Aerobic exercise: Brisk walking, cycling, swimming — 30 min, 5 days a week
- Resistance training: 2–3 sessions/week of weight training reduces liver fat independently of aerobic exercise
- HIIT (High-Intensity Interval Training): 20 minutes, 3 times/week — highly effective
- Daily movement: Avoid prolonged sitting; stand or walk for 5 minutes every hour
Medical Treatment for Advanced Fatty Liver
For Grade 3 MASH with significant fibrosis, Dr. Srinivas Bojanapu evaluates patients for emerging pharmacological options and monitors progression with:
- Fibroscan (transient elastography) every 6–12 months to track fibrosis
- Vitamin E and pioglitazone in selected non-diabetic MASH patients
- GLP-1 receptor agonists (semaglutide) for eligible patients with obesity and diabetes
- HCC (liver cancer) surveillance every 6 months in those with cirrhosis
- Transplant evaluation when cirrhosis decompensates
The Good News
Grades 1 and 2 fatty liver can be completely reversed in 3–6 months with sustained lifestyle changes. Even Grade 3 MASH patients show dramatic improvement with consistent effort. Early action makes all the difference.
When to See Dr. Srinivas Bojanapu
- Fatty liver found incidentally on ultrasound
- Raised SGPT / SGOT (liver enzymes) on blood tests
- Diabetes or prediabetes with abnormal liver tests
- Fibroscan showing significant fibrosis (F2 or above)
- Grade 3 fatty liver not responding to 6 months of lifestyle change
- Signs of portal hypertension or cirrhosis
