New Delhi: On the occasion of World Liver Day, medical experts are urging a shift in public understanding of liver disease, highlighting that blaming dietary fat alone is both outdated and misleading. Instead, growing scientific evidence points to poor metabolic health and excess calorie intake as the primary drivers behind the alarming rise in fatty liver disease.
A recent global study published in The Lancet Gastroenterology & Hepatology estimates that nearly 1.3 billion people were living with metabolic dysfunction-associated steatotic liver disease (MASLD) in 2023, with projections indicating a rise to 1.8 billion by 2050. The surge is closely linked to increasing rates of obesity, diabetes, insulin resistance and sedentary lifestyles—trends that are becoming increasingly prevalent in India.
Experts warn that India is facing a silent liver health crisis, as early-stage liver disease often presents no visible symptoms. Many individuals remain unaware of fat accumulation in the liver until the condition progresses to serious complications such as inflammation, fibrosis, cirrhosis or even liver cancer.
“Fatty liver disease is not just about consuming fats. The real issue lies in excess calorie intake and poor metabolic health,” said Dr Saurabh Bansal, Gastrointestinal, Laparoscopic, Cancer and Robotic Surgery Specialist. “When the body consistently consumes more energy than it burns, the liver stores the excess as fat, regardless of whether those calories come from carbohydrates, sugars or fats.”
While dietary composition plays a role, experts emphasize that overall calorie balance and lifestyle choices are more critical. Scientific studies indicate that individuals with fatty liver often consume more total calories, even if the proportion of fats, carbohydrates and proteins in their diet is similar to that of healthy individuals.
At the same time, the quality of fats consumed remains important. Nutrition experts recommend incorporating healthier fat sources such as nuts, seeds, fish and vegetable oils like mustard and groundnut oil in moderation and rotation. These contain beneficial fatty acids and antioxidants that support lipid balance and metabolic health when part of a balanced diet.
Health professionals stress that protecting liver health does not require extreme dietary restrictions but rather sustainable lifestyle changes. Regular physical activity, maintaining a healthy weight, limiting alcohol intake and routine screening for blood sugar and cholesterol are key preventive measures. Research shows that even a 5–7% reduction in body weight can significantly reduce liver fat and improve inflammation.
As India grapples with rising metabolic disorders, experts call for stronger public awareness, improved food labelling and healthier food environments in schools and workplaces.
“A healthy liver is built through balanced habits, not fear of a single nutrient,” Dr Bansal added. “It is time to move beyond myths and adopt a science-based approach to long-term health.”
