Placebo Comparator: Placebo
Inactive ingredients include maltose, lemon flavoring (or corn starch if unflavored), and silicon dioxide.
Dietary Supplement: Placebo
A matched placebo to VSL#3 will be provided. The placebo will be identical to the active VSL#3 probiotic in aspects such as packaging, color, taste, texture, shape, and odor. The placebo will not contain active ingredients. The study team will supply each participant with all necessary packets on a weekly or bi-weekly basis within 1-2 weeks after their first visit. The placebo is provided in powder form and needs to be mixed with liquid for consumption. For this reason, the study team will also provide participants with zero calorie sugar fee beverages to mix their packet with (e.g., vitamin water zero).
Active Comparator: VSL#3
VSL#3 is classified as a medical food that is specially formulated and processed to provide a precise mixture of 8 strains of bacterial species with potential synergistic relationships. These strains include Streptococcus thermophilus, Bifidobacterium breve, Bifidobacterium longum, Bifidobacterium infantis, Lactobacillus acidophilus, Lactobacillus plantarum, Lactobacillus paracasei, and Lactobacillus delbrueckii subsp. bulgaricus.
Dietary Supplement: VSL#3
VSL#3 will provide active packets. Subjects will take 2 to 3 packets per day with for 16 weeks. The study team will supply each participant with all necessary packets on a weekly or bi-weekly basis within 1-2 weeks after their first visit. VSL#3 probiotic is provided in powder form and needs to be mixed with cold, non-fizzy liquid for consumption. For this reason, the study team will also provide participants with zero calorie sugar fee beverages to mix their packet with (e.g., vitamin water zero with stevia).
- Change in abundance of gut microbiome and gut hormones measured pre and post blood and stool sample collections. [ Time Frame: 16 weeks ]To determine whether probiotic (VSL#3) supplementation affects gut microbiome and gut hormones involved with appetite regulation in obese young Hispanics.
- Interaction between gut microbiome and liver fat, fibrosis, obesity, and glycemia measured pre and post blood and stool sample collections and through Dxa and MRI scans.. [ Time Frame: 16 weeks ]To determine whether there are any relationships between changes in the gut microbiome and changes in liver fat, fibrosis, obesity, and glycemia after 16 weeks of probiotic supplementation.
