For the millions of people globally, "healthy eating" is a privilege rather than a default choice. From high costs of healthy foods to nutritious food systems that favor profit over health, the obstacles to a liver-supportive diet are real. Among popular diets, the ketogenic diet, or keto, has become extremely popular for its fast weight loss advantages but beneath its high-fat, low-carb framework is a less-discussed issue—how prolonged ketosis can silently burden the liver.Your liver is your body's control center for detoxification and metabolic regulation. It processes toxins, digests nutrients, produces bile to break down fats, stores energy, and even produces blood-clotting factors.“While many factors shaping our diet lie outside personal control—like zoning laws, school meal policies, and labeling—what remains in our hands is the knowledge of how our food choices impact our health,” says Nutritionist and Diabetes & Inflammation Specialist, Khushboo Jain Tibrewala.However, these processes can be easily undone by modern lives—too much booze, sweet diets, lazy lifestyles, and, ironically enough, some hardcore dietary regimes like prolonged keto. The liver's tough, true, but get it working around its metabolic tipping point for sustained periods, and it begins to exhibit symptoms—a lot of which come in the form of abnormal liver enzymes and inflammation.What Is Ketosis?Ketosis is a metabolic process by which your body shifts from glucose (carbohydrate) to fat fueling. Carbohydrates in your diet, under normal conditions, get digested into glucose, which gets utilized by the body as fuel. In ketosis, fats are metabolized into ketone bodies—an additional fuel for brain and muscle tissue.As per Tibrewala, this condition can be triggered by, "A ketogenic diet—intentionally low in carbohydrates and high in fat, or in severe cases of uncontrolled diabetes, where glucose metabolism is disturbed."Although created initially to control epilepsy, the keto diet is today mainstream. Individuals remain in ketosis for weeks, months, even years. But is such long-term adaptation liver-friendly?Overburdening the Liver"The liver is at the center of making ketones," Tibrewala says. "And that process of metabolism is taxing." Sustained levels of ketosis lead to the liver breaking down fats continuously, which in turn increases liver enzymes—namely ALT (alanine aminotransferase) and AST (aspartate aminotransferase).Clinical research indicates that keto dieters who eat this way in the long term tend to develop signs of hepatic stress even when they do not have fatty liver disease. High enzymes don't necessarily mean instant damage to the liver—but they do signal that the liver is burning out. Left untreated, this can result in inflammation, fibrosis, or even non-alcoholic steatohepatitis (NASH) in vulnerable people.Low-Carb, Low-FibreA significant downfall of ketosis is the drastic reduction of dietary fibre, a substance which is rich in carb-foods such as fruits, whole grains, and legumes. "Fibre is not only for digestion—it's food for your gut microbiome," adds Tibrewala.A fiber-deficient diet upsets the balance of bacteria in the gut, permitting deleterious strains to dominate. The outcome? Increased permeability of the gut, systemic inflammation, and toxic load—altogether placing further stress on the liver. The organ is thus forced to struggle even harder to detoxify these toxins, added to its already high workload under ketosis.Hidden Harm of Processed Keto ProductsIronically, most keto believers resort to processed foods to fulfill their macronutrient needs. From protein powders and MCT oils, snack bars, to exogenous ketone supplements, they are filled with preservatives, additives, and in some, heavy metals."These artificial substances are processed through the liver, which is yet another source of stress," Tibrewala observes. Gradually, this higher toxic load—combined with compromised gut integrity—can drive the liver toward pathology, even if there are no obvious symptoms.Therapeutic vs. Trendy: When Does Ketosis Make Sense?It’s important to acknowledge that ketosis, in short, supervised intervals, may have therapeutic potential—particularly for managing epilepsy, obesity, or insulin resistance. But long-term, unsupervised ketosis can be a slippery slope.A liver in constant ketone-production mode is analogous to a machine running non-stop—it wears out faster. “Our liver thrives on balance, moderation, and nourishment—not on extremes,” emphasizes Tibrewala.What Can You Do for Your Liver?Select balanced nutrition: Eat whole grains, plant protein, and high fibre foods.Steer clear of ultra-processed keto treats and go for whole-food fats such as avocado, nuts, and seeds.Restrict ketosis to short cycles, if at all, and always after consulting a health professional.Emphasize gut health with probiotics, prebiotics, and fermented foods. A healthy gut lightens the burden on your liver.Drink water and move around—two simple but potent aids to liver detox and metabolic equilibrium.In the quest for weight reduction or "biohacking," extended ketosis has been hailed as revolutionary but your liver- the powerhouse of your metabolism tends to take the hit.Khushboo Jain Tibrewala is a Nutritionist and Diabetes & Inflammation specialist at The Health Pantry in India
