Studies Raise Questions About Keto's Impact on Liver and Heart Health

While short-term ketogenic diets may aid weight loss, new research links prolonged ketosis to liver stress, impaired insulin secretion, and cardiovascular problems Long-term fat reliance increases circulating free fatty acids, burdening the liver, disrupting glucose regulation, and weakening metabolic flexibility — key factors in overall energy stability and heart health Elevated liver enzymes and triglyceride levels on keto indicate hepatic overload. This signals that the body is struggling to manage excess fat turnover and oxidation Treat keto as a short-term metabolic intervention, not a lifestyle diet. Gradually reintroduce whole-food carbohydrates to support steady energy, hormonal balance, and overall metabolic health To support balanced metabolism and long-term liver and heart health, keep total fat below 30% of daily calories, eliminate seed oils from your diet, and consume sufficient dietary fiber
