This pilot study suggests that the administration of a multi-strain probiotic containing lactobacillus and bifidobacterium species can help reduce body weight and cardiovascular risk factors in obese patients. This effect may be related to the production of short-chain fatty acids.
Previous data suggested that anti-obesity interventions, such as percutaneous electric neurostimulation and probiotics, could reduce body weight and cardiovascular (CV) risk factors by attenuation of microbiota alterations. However, potential mechanisms of action have not been unveiled, and the production of short-chain fatty acids (SCFAs) might be involved in these responses. This pilot study included two groups of class-I obese patients (N = 10, each) who underwent anti-obesity therapy by percutaneous electric neurostimulations (PENS) and a hypocaloric diet (Diet), with/without the administration of the multi-strain probiotic (Lactobacillus plantarum LP115, Lactobacillus acidophilus LA14, and Bifidobacterium breve B3), for ten weeks. Fecal samples were used for SCFA quantification (by HPLC-MS) in relation to microbiota and anthropometric and clinical variables. In these patients, we previously described a further reduction in obesity and CV risk factors (hyperglycemia, dyslipemia) after PENS-Diet+Prob compared to PENS-Diet alone. Herein, we observed that the administration of probiotics decreased fecal acetate concentrations, and this effect may be linked to the enrichment of Prevotella, Bifidobacterium spp., and Akkermansia muciniphila. Additionally, fecal acetate, propionate, and butyrate are associated with each other, suggesting an additional benefit in colonic absorption. In conclusion, probiotics could help anti-obesity interventions by promoting weight loss and reducing CV risk factors. Likely, modification of microbiota and related SCFA, such as acetate, could improve environmental conditions and permeability in the gut.
