· An imbalance of the gut microbiota with a relative increase in Firmicutes versus Bacteroidetes is associated with the pathogenesis of obesity.
· Dysbiosis is associated with microbial genes associated with short-chain fatty acids (SCFA) production and increased colonic SCFA levels. SCFAs have also been shown to regulate appetite and satiety hormones, which can affect food intake and energy balance.
· A dietary high-fat intake is reportedly associated with increased plasma lipopolysaccharide. Altered Toll-like receptor-4 signaling leads to propagating the cascade of further inflammation and promoting insulin resistance. |

∙ Microbial colonization primarily occurs after birth but there may be some colonization in utero, although this remains highly controversial.
∙ Maternal factors during pregnancy affect the infant microbiota: diet, weight, gestational weight gain, and antibiotic usage.
∙ Microbes are passed from mother-to-infant during and after birth. Delivery mode, breastfeeding, early life antibiotic, and proton pump inhibitor treatment have the largest effects on microbial composition in early life.
∙ The early life gut microbiome plays an important role in the development of the immune system and metabolism. |
