Brief Summary

This study aims to evaluate the modifications in body composition and insulin resistance state in patients with grade II and III obesity included in an interventional lifestyle changes program and treated with probiotics (1 x 1011 CFU) or placebo for 16 weeks and its associations with intestinal microbiota behaviour

Detailed Description

A randomized placebo-controlled clinical trial will take place in which both arms will be included in an interventional lifestyle changes program at the Clinic for Integral Treatment of patients with Diabetes and Obesity. The study group will be treated with probiotics (1 x 1011 CFU) for 16 weeks and will be compared to a control group who will receive placebo.

Changes in body composition (weight, BMI, fat percentage, fat mass, lean body mass) and insulin resistance indexes (HOMA, insulin sensitivity index and Quicki) will be evaluated in patients with obesity receiving probiotics (1 x 1011 CFU) for 16 weeks, and compared to a placebo group.

Changes in metabolic profile (glucose tolerance test, glycosylated haemoglobin, lipid profile, leptin and transaminases) in patients with obesity receiving probiotics (1 x 1011 CFU) for 16 weeks, and compared to a placebo group.

Changes in microRNAs profile (miR-133 and miR-27 in patients with obesity receiving probiotics (1 x 1011 CFU) for 16 weeks, and compared to a placebo group.

The threshold for basic tastes will be evaluated (salted, bitter, acid, sweet) and will be evaluated in those patients receiving probiotics (1 x 1011 CFU) for 16 weeks, and compared to the group receiving only placebo.

Changes in intestinal microbiota behaviour will be evaluated in participants with obesity receiving probiotics (1 x 1011 CFU) for 16 weeks, and compared to the group receiving placebo.

Control groupPlaceboSubjects will be randomly assigned to receive a daily nightly dose (4 capsules) of placebo for 16 weeks. Placebo presentation will have the same aspect as those of the probiotic treatment.
Study groupProbioticsSubjects will be randomly assigned to receive a daily nightly dose (4 capsules) of probiotics for 16 weeks. Probiotics (LACTIPAN®) include 2.5 billion CFU of 6 different strains of live microorganisms, such as Lactobacillus acidophilus (1.0 x 109 CFU), Lactobacillus casei (1.0 x 109 CFU), Lactobacillus rhamnosus (4.4 x 108 CFU), Lactobacillus plantarum (1.76 x 108 CFU), Bifidobacterium infantis (2.76 x 107 CFU), Streptococcus thermophilus (6.66 x 105 CFU) and 50 mg of oligofructose enriched inulin.
