Background

Previous research (covered in a study summary from last month) has shown a positive effect of garlic on non-alcoholic fatty liver disease (NAFLD). The researchers in this study continued this line of inquiry by investigating the effects of garlic powder on insulin resistance, oxidative stress, and body composition.

The study

This study randomized 90 individuals with NAFLD to supplement 400 mg of garlic powder or placebo four times per day for 12 weeks. The participants’ dietary habits, physical activity, blood markers of glycemic control and oxidative stress, and body composition were recorded at baseline, and 6 and 12 weeks into the study.

The results

The treatment group experienced increased muscle mass and reduced waist circumference, body fat percentage, fasting blood glucose and insulin, and markers of oxidative stress. There was no change in average BMI or body weight.
