Summary

The very low carbohydrates diet (VLCKD) induces liver steatosis amelioration. Lysosomal acid lipase (LAL) deficiency plays a role in fats accumulation in liver. To date, no studies have assessed LAL activity in morbid obesity. The aim of our study is to evaluate VLCKD impact on metabolic/vascular parameters and LAL activity in obese patients.

A VLCKD is administered for 25 days to 52 morbid obese patients (BMI 44.78.3 kg/m, age 4912.5 years); at baseline and after diet we evaluated: BMI, glyco-lipidic pattern, abdominal ultrasonography (liver steatosis and visceral fat area) and flow-mediated dilation (FMD). In a subgroup of 20 patients we also tested lysosomal acid lipase (LAL)-activity. A group of healthy normal weight subjects (age 4313, BMI 22.82.6 kg/m) was also included in the study.
