effect of the probiotic sf68® on body composition and low-to-moderate cardiovascular risk

Conditions: Overweight and Obesity

Summary: obesity is a multifactorial disorder of energy balance, characterized by an imbalance between energy intake and energy consumption. in recent decades, the prevalence of obesity has reached epidemic proportions. advances in scientific research have enabled better characterization of the etiology of obesity, highlighting the potential contribution of factors not traditionally considered to be involved in changes in energy balance and body composition, such as the gut microbiota. oral administration of probiotics has been proposed as a valid way to modulate the gut ecosystem to promote weight reduction. preliminary data from a preclinical study in mouse models suggest that the dietary supplement sf68® containing the probiotic enterococcus lactis as well as phytosterols and (6s)-5-methyltetrahydrofolic acid has the ability to significantly counteract weight gain. in addition to modulating the composition of the gut microbiota, it also has an impact on decreasing the levels of total cholesterol, low-density cholesterol (ldl), triglycerides, homocysteine, il-1 β and lps binding protein (lbp). although exercise and diet are the first lines of intervention to be recommended, there are often failures or poor results. there is currently increased interest in alternative and effective shorter-term, non-pharmacological approaches to weight control that involve the use of natural active ingredients. thus, the aim of this intervention study is to investigate whether a supplementation with sf68® could be beneficial for the weight reduction and the improvement of cardiovascular risk profile of people with overweight or obesity.
