Lysosomal Acid Lipase As A Molecular Target Of The Very Low Carbohydrate Ketogenic Diet In Morbidly Obese Patients The Potential Effects On Liver Steatosis And Cardiovascular Risk Factors

This study examined how a very low-carb ketogenic diet (VLCKD) affects severely obese patients who were preparing for weight-loss surgery. The researchers focused on an enzyme called lysosomal acid lipase (LAL), which helps break down fats in our cells. When this enzyme doesn't work properly, it can contribute to fatty liver disease - a common problem in obese individuals that makes surgery riskier.

The study followed 52 severely obese patients who followed a strict ketogenic diet for 25 days. This type of diet is extremely low in carbohydrates and higher in protein, forcing the body to burn fat for energy instead of sugar. The researchers measured various health markers before and after the diet, including blood sugar, cholesterol levels, body weight, and the activity of the LAL enzyme.

The results were encouraging across multiple measures. Patients lost significant weight and showed improvements in blood sugar control and cholesterol levels. Importantly, the activity of the LAL enzyme increased substantially, and fewer patients had severe fatty liver disease after the diet. The improved enzyme function likely helped their bodies process fats more efficiently, contributing to better liver health.

These findings suggest that short-term ketogenic diets may help prepare severely obese patients for surgery by improving their metabolic health and reducing liver fat accumulation. For patients considering metabolic interventions, this research highlights how targeted dietary approaches can activate beneficial cellular processes and improve multiple health markers simultaneously, potentially making surgical procedures safer and more effective.
