Fatty Liver & Cholesterol

A high-protein, whey-concentrate-supplemented diet may reduce the risk of both non-alcoholic fatty liver disease, as well as cardiovascular disease in obese patients, according to Dr. Bortolotti’s study.

Murielle Bortolotti, from the University of Lausanne, and colleagues gave 11 obese, non-diabetic females diet supplementation with three 20 gram servings of whey protein per day for about a month (a total of 60 grams daily). At the beginning of the study, the fat inside the livers of the overweight women (technically known as intra-hepatocellular lipid concentrations, or IHCL) ranged between 1.9 and 20.5%.

After four weeks of consuming whey protein, the women’s IHCL had plummeted by about 21%, fasting plasma triglycerides decreased by 15%, and total plasma cholesterol concentration dropped by over 7%. Dr. Bortolotti and her co-workers pointed out that the IHCL reduction was not accompanied by any major changes in body weight or body fat mass.

“This therefore indicates that the improved IHCL and plasma triglyceride profiles were to be attributed to an effect of protein rather than to changes in body composition,” the research team said in a media statement. They added that their study suggests that a high protein whey supplemented diet may reduce the risk of both non-alcoholic fatty liver disease as well as cardiovascular disease in obese patients
