How this Fatty Liver Risk Calculator works
Enter your age, sex, height, weight, and waist circumference, plus metabolic history (diabetes, blood pressure, elevated liver enzymes, PCOS, sleep apnea), lifestyle factors (alcohol, physical activity, diet quality, sugary drinks), and any symptoms (fatigue, abdominal discomfort, unexplained weight loss).
We apply an evidence-based weighted scoring system for the Indian population—higher risk points for obesity, central adiposity, type 2 diabetes, prediabetes, heavy alcohol, sedentary lifestyle, poor diet, elevated liver enzymes, and metabolic comorbidities. Risk levels: Low (0–20 pts), Moderate (21–45), High (46–70), Very High (71+). Results include top risk factors with point explanations, BMI assessment using Asian-Pacific cutoffs (overweight ≥23 kg/m²), a personalized weight-loss target (7–10% body weight—the most proven reversal strategy), Mediterranean-style diet tips adapted for Indian foods, exercise guidance, and liver testing recommendations.
If your result is High or Very High, we prompt you to book liver function tests (ALT, AST, GGT) and an abdominal ultrasound—only imaging and blood tests confirm fatty liver and its severity; this tool screens lifestyle and clinical risk. Scroll below for disease stages, Indian diet guidance, sample meal plans, exercise prescription, lab reference tables, and FAQs.

Fatty Liver Risk Calculator – NAFLD/MASLD Screening, Symptoms & Diet India
Millions search "fatty liver calculator", "NAFLD risk", "fatty liver symptoms India", and "how to reverse fatty liver" each year. Fatty liver disease—now often called MASLD (metabolic dysfunction-associated steatotic liver disease)—affects roughly 25–30% of Indian adults and is the leading cause of chronic liver disease. Obesity, diabetes, central adiposity, refined-carb diets, and sedentary lifestyles drive widespread hepatic steatosis. Our free Fatty Liver Risk Calculator uses an evidence-based weighted scoring system to estimate your risk level, identify top risk factors, calculate a personalized weight-loss target, provide Mediterranean-style diet and exercise guidance, and prompt liver testing when risk is High or Very High.
Pair results with our Diabetes Risk Calculator, Visceral Fat Risk Calculator, and Alcohol Impact Calculator for a complete metabolic and liver health picture.
Why Assess Fatty Liver Risk?
Fatty liver is the accumulation of excess triglycerides in hepatocytes (liver cells). Most cases are metabolic—linked to insulin resistance, obesity, and diet—rather than alcohol. Early fatty liver (simple steatosis) is often reversible with 7–10% body weight loss. Advanced stages (NASH/MASH with fibrosis) can progress to cirrhosis and liver failure without treatment.
South Asians develop fatty liver at lower BMI thresholds (overweight ≥23 kg/m² by Asian criteria). Most people have no symptoms—discovery often happens on routine blood tests (elevated ALT/AST) or abdominal ultrasound. This calculator helps you understand whether testing is warranted based on metabolic risk factors.
1What You Enter
Body measurements
- Age — risk rises after 45
- Sex — men have higher NAFLD rates
- Height & weight — BMI with Asian cutoffs
- Waist circumference — ≥90 cm men / ≥80 cm women
Metabolic & medical history
- Diabetes status — none, prediabetes, type 2
- High blood pressure
- Elevated liver enzymes (prior ALT/AST)
- PCOS (women), sleep apnea, hypothyroidism
- Family history of diabetes or fatty liver
Lifestyle inputs
- Alcohol consumption — none, moderate, heavy
- Physical activity — active, moderate, sedentary

Example (Very High risk — man, 48, Delhi)
Age 48, male, BMI 31, waist 98 cm, type 2 diabetes, sedentary, poor diet, daily sugary drinks, elevated ALT on past labs → Very High risk, ~8 kg weight-loss target, get-tested prompt for LFTs + ultrasound.
Example (Low risk — woman, 35, active)
Age 35, female, BMI 22, waist 72 cm, no diabetes, active lifestyle, healthy diet, no alcohol, no symptoms → Low risk, maintain current habits, routine screening if family history present.
2Scoring Logic — Weighted Risk Factors
High-weight risk factors
The score increases most for: type 2 diabetes (+18 pts), obesity (BMI ≥30) (+18 pts), heavy alcohol (+18 pts), high waist (+16 pts), elevated liver enzymes (+14 pts), prediabetes (+14 pts), and overweight (BMI 25–29.9) (+12 pts). Moderate weights apply to PCOS, sedentary lifestyle, poor diet, Asian overweight (BMI 23–24.9), moderate alcohol, and metabolic comorbidities.
Risk level thresholds
- Low — 0–20 points
- Moderate — 21–45 points
- High — 46–70 points
- Very High — 71+ points
Weight-loss target
We recommend 7–10% body weight loss based on your BMI—7% for overweight, 10% for obesity. This is the most proven intervention to reverse early fatty liver.

Understanding NAFLD, MASLD & NASH — Disease Stages
NAFLD (non-alcoholic fatty liver disease) is the older term for excess liver fat without heavy alcohol use. In 2023, global guidelines introduced MASLD (metabolic dysfunction-associated steatotic liver disease)—same core condition, emphasising the metabolic drivers (obesity, insulin resistance, diabetes). Simple steatosis means fat accumulation without significant inflammation—often reversible. NASH/MASH (steatohepatitis) adds liver inflammation and cell injury; without treatment it can progress to fibrosis, cirrhosis, and liver failure.
| Stage | What happens | Reversible? |
|---|---|---|
| Simple steatosis | Fat in liver cells; enzymes may be normal | Yes — with lifestyle change |
| Steatohepatitis (NASH/MASH) | Fat + inflammation; ALT/AST often elevated | Often — early stages respond to weight loss |
| Fibrosis (F1–F3) | Scar tissue replaces healthy liver | Partially — specialist care needed |
| Cirrhosis (F4) | Advanced scarring; liver function impaired | Limited — focus on preventing progression |
Most people with fatty liver are in early stages and never develop cirrhosis—but diabetes, obesity, and alcohol accelerate progression. Early screening with this calculator plus liver tests catches disease when reversal is still possible.
Symptoms of Fatty Liver — What to Watch For
Early / often silent
- No symptoms in 70–80% of cases
- Mild fatigue or low energy
- Vague right upper abdominal discomfort
- Elevated ALT/AST on routine blood tests
- Fatty liver found incidentally on ultrasound
Advanced / urgent signs
- Unexplained weight loss
- Yellow eyes or skin (jaundice)
- Abdominal swelling (ascites)
- Dark urine or pale stools
- Easy bruising or bleeding (urgent care)
Symptoms overlap with diabetes, thyroid disorders, and anaemia—liver function tests and imaging confirm the cause.
Liver Test Reference — ALT, AST & Ultrasound
| Test | Normal range | Elevated / concerning |
|---|---|---|
| ALT (men) | 7–40 U/L | >40 U/L |
| ALT (women) | 7–35 U/L | >35 U/L |
| AST | 10–40 U/L | >40 U/L |
| GGT | 9–48 U/L (varies by lab) | Elevated with alcohol or bile duct issues |
| Abdominal ultrasound | Normal liver echotexture | Increased echogenicity = fatty liver |
Elevated ALT/AST with ultrasound showing hepatic steatosis confirms fatty liver. Normal enzymes do not rule out NAFLD—up to 30% of cases have normal ALT. This calculator screens risk—it does not replace these tests.
Fatty Liver in India — Key Statistics
- Prevalence: NAFLD/MASLD affects an estimated 25–30% of Indian adults—higher in urban populations
- Diabetes link: Up to 70% of type 2 diabetics have coexisting fatty liver
- Lower BMI risk: South Asians develop fatty liver at BMI ≥23—Asian overweight cutoff, not Western ≥25
- Lean NAFLD: 10–20% of cases occur in people with normal BMI but high waist or poor diet
- Silent disease: Most cases are discovered on routine health check-ups, not from symptoms
- Leading cause: MASLD is now the top cause of chronic liver disease worldwide, surpassing viral hepatitis in many regions
- Diet drivers: High refined carbs, fried snacks, sugary beverages, and sedentary urban lifestyles are major modifiable factors
BMI & Waist Cutoffs — Asian vs Western Standards
| Measure | Asian cutoff (WHO) | Western cutoff |
|---|---|---|
| Overweight (BMI) | ≥23 kg/m² | ≥25 kg/m² |
| Obesity (BMI) | ≥25 kg/m² | ≥30 kg/m² |
| Waist (men) | ≥90 cm | ≥102 cm |
| Waist (women) | ≥80 cm | ≥88 cm |
This calculator uses Asian-Pacific BMI and waist thresholds because South Asians accumulate visceral fat at lower body weights. Pair with our BMI Calculator and Waist-to-Height Ratio for deeper body composition screening.
Risk Scoring Points Reference
| Factor | Points | Why it matters |
|---|---|---|
| Type 2 diabetes | +18 | Insulin resistance drives hepatic fat |
| Obesity (BMI ≥30) | +18 | Strongest lifestyle driver of NAFLD |
| Heavy alcohol (>14 units/week) | +18 | Alcoholic + metabolic liver fat overlap |
| High waist (≥100 cm M / ≥90 cm F) | +16 | Central adiposity predicts liver steatosis |
| Elevated liver enzymes (prior labs) | +14 | Suggests active hepatic inflammation |
| Prediabetes / borderline sugar | +14 | Insulin resistance precedes frank diabetes |
| Overweight (BMI 25–29.9) | +12 | Metabolic risk even below Western obesity cutoff |
| PCOS (women) | +12 | Insulin resistance cluster with fatty liver |
| Elevated waist (≥90 cm M / ≥80 cm F) | +12 | Abdominal obesity per Indian guidelines |
| Sedentary lifestyle | +10 | Inactivity independent of diet risk |
| Poor diet (fried/refined carbs) | +10 | Fructose and maida drive liver fat |
| Asian overweight (BMI 23–24.9) | +8 | South Asians develop NAFLD at lower BMI |
Fatty Liver Risk Tiers (Educational)
| Level | Score | Action |
|---|---|---|
| Low | 0–20 | Maintain healthy lifestyle; screen if family history |
| Moderate | 21–45 | Optimise diet & exercise; consider LFTs in 3–6 months |
| High | 46–70 | Book LFTs + abdominal ultrasound; target 7–10% weight loss |
| Very High | 71+ | Urgent liver evaluation; rule out advanced fibrosis |
Worked Example — Step-by-Step
A 52-year-old man in Hyderabad: BMI 28.4, waist 94 cm, type 2 diabetes, moderate alcohol, sedentary, poor diet, daily sugary drinks, previously elevated ALT:
- Age 52, male: +8 pts (45–59) + 6 pts (male) = +14 pts
- BMI 28.4 (overweight): +12 pts
- Waist 94 cm (elevated): +12 pts
- Type 2 diabetes: +18 pts
- Moderate alcohol: +10 pts
- Sedentary + poor diet + daily sugary drinks: +10 + 10 + 8 = +28 pts
- Elevated liver enzymes: +14 pts
- Total score: ~108 points → Very High risk
- Weight-loss target: ~8 kg (7%); get-tested prompt for LFTs + ultrasound
Diet for Fatty Liver — Indian Food Guidance
Eat more
- Whole grains — bajra, jowar, brown rice, oats, dalia
- Vegetables and salads at every meal
- Legumes — masoor dal, chana, rajma, sprouts
- Nuts, seeds, and healthy oils (mustard, olive, groundnut)
- Fatty fish if non-vegetarian — bangda, surmai
- Green tea instead of sugary chai
Limit or avoid
- Refined flour (maida), white bread, bakery items
- Fried snacks — samosa, pakora, bhatura, chips
- Sugary drinks — soft drinks, packaged juices, sweet lassi
- Sweets, mithai, and excessive jaggery
- Repeatedly heated cooking oil (trans fats)
- Alcohol — especially if enzymes are elevated
Sample Indian Meal Plan for Fatty Liver
| Meal | Example | Why it helps |
|---|---|---|
| Breakfast | Vegetable upma (oats/dalia) + sprouts + green tea | Whole grains, fibre, no added sugar |
| Mid-morning | Handful of almonds or roasted chana | Healthy fats, protein, stable blood sugar |
| Lunch | Brown rice + masoor dal + mixed sabzi + salad with lemon | Low-GI carbs, legumes, vegetables, fibre |
| Evening | Buttermilk (chaas) or green tea — no biscuits | Probiotics; avoids refined snack calories |
| Dinner | 2 multigrain rotis + palak paneer + cucumber raita | Early light dinner; vegetables and protein |
Aim for 25–30 g fibre daily, limit dinner to 70% of lunch portion size, and finish eating 2–3 hours before bed. Non-vegetarians can add grilled fish (bangda, surmai) 2–3 times weekly.
Exercise Prescription for Fatty Liver
| Type | Target | Indian examples |
|---|---|---|
| Aerobic | 150–300 min/week moderate | Brisk walking, cycling, swimming, dancing |
| Resistance | 2–3 sessions/week | Bodyweight squats, resistance bands, gym weights |
| NEAT (daily movement) | 8,000–10,000 steps/day | Walk after meals, take stairs, stand every hour |
| Intensity guide | Talk-test moderate | Can speak in sentences but not sing during activity |
Studies show exercise reduces liver fat even without weight loss—but combining both gives the best results. Start with 20–30 minutes daily walking if currently sedentary. Use our Calories Burned Calculator to estimate activity energy expenditure.
Reversing Fatty Liver — Lifestyle Interventions
Weight loss of 7–10% is the most effective treatment— reduces liver fat, inflammation, and fibrosis progression. Exercise (150+ min/week moderate activity plus resistance training) reduces hepatic fat even without major weight change. Diet changes—Mediterranean pattern adapted to Indian foods—cut refined carbs and fructose. Alcohol reduction is essential if you drink regularly.
Advanced fibrosis (NASH/MASH) may need specialist care including medications under trial or approved in some regions. Early detection through this screening plus liver tests gives the best chance of reversal.
Lean NAFLD — Fatty Liver at Normal BMI
Lean NAFLD affects 10–20% of fatty liver patients who have normal BMI but carry excess visceral fat, insulin resistance, or poor dietary patterns. South Asians are especially prone—thin arms and legs with a protruding abdomen ("thin-outside-fat-inside") is a classic pattern. Waist circumference above 80 cm (women) or 90 cm (men) at normal BMI still warrants liver screening.
If your BMI looks healthy but you have prediabetes, high triglycerides, PCOS, or a family history of diabetes, run this calculator and consider our Insulin Resistance (HOMA-IR) Calculator with fasting glucose and insulin lab values.
How to Prepare for Liver Blood Tests & Ultrasound
- Request liver function tests (ALT, AST, GGT, bilirubin, albumin) plus fasting glucose and HbA1c
- Request lipid profile (triglycerides, HDL, LDL)—dyslipidemia clusters with NAFLD
- Fasting 8–12 hours (water only) is usually required for glucose and lipids—confirm with your lab
- Abdominal ultrasound needs no fasting—drink water for a full bladder if instructed
- Avoid alcohol 48–72 hours before LFTs for a clearer baseline
- Bring previous reports for trend comparison
- Cost: approximately ₹800–2500 for LFTs + ultrasound at Thyrocare, Dr Lal PathLabs, SRL, Metropolis
- Ask about FibroScan if enzymes are persistently elevated—quantifies fibrosis without biopsy
- Rule out hepatitis B (HBsAg) and hepatitis C (anti-HCV) if cause is unclear
Who Is at Highest Risk in India?
Lifestyle risk
- Overweight or obese (BMI ≥23 by Asian criteria)
- Central adiposity — large waist despite normal weight
- Sedentary desk jobs with minimal physical activity
- High intake of fried food, maida, sweets, sugary beverages
- Regular alcohol consumption above safe limits
Medical risk
- Type 2 diabetes or prediabetes
- PCOS, hypothyroidism, obstructive sleep apnea
- Hypertension and metabolic syndrome
- Family history of diabetes or liver disease
- Previously elevated ALT/AST on health check-ups
When to Get Tested & See a Doctor
Book liver tests if
- Calculator result is High or Very High
- Type 2 diabetes plus overweight or obesity
- Previously elevated liver enzymes
- Waist above 90 cm (men) or 80 cm (women)
- Family history of liver disease or diabetes
Seek urgent care if
- Yellow eyes or skin (jaundice)
- Severe right upper abdominal pain
- Vomiting blood or black tarry stools
- Rapid abdominal swelling
- Confusion or extreme fatigue with known liver disease
Common Mistakes When Managing Fatty Liver
- Relying on "liver detox" supplements or kadha without medical evidence—they do not reverse steatosis
- Crash dieting or very-low-calorie diets—these can worsen liver stress; aim for 0.5–1 kg/week sustainable loss
- Ignoring fatty liver because ALT is normal—up to 30% of NAFLD cases have normal enzymes
- Continuing moderate alcohol while treating metabolic fatty liver— alcohol adds direct hepatotoxicity
- Skipping follow-up tests after lifestyle changes—retest LFTs at 3–6 months to confirm improvement
- Focusing only on BMI and ignoring waist circumference—central fat drives liver disease even at "normal" weight
