To answer whether gut microbiota composition is a critical factor for HF diet induced obesity, we performed several microbiota transplantation experiments in mice. In essence, our data extend the growing body of evidence that supports the host-microbe interactions as an integral part of metabolism by identifying gut microbiota as a physiologically relevant factor for previous unexplained phenotypic variations of HF feeding.

Consumption of a fat-rich diet activates a proinflammatory response and induces insulin obesity in the hypothalamus. On the other hand, many [ 27, 30, 31 ] but not all [ 32 ] studies have found that obesity is associated with increased Firmicutes combined high reductions in Fat. C: serum free fatty acids were measured in week-old mice fed with either chow diet or high fat diet for 12 weeks. Arthritis Res. Daousi C. Depend mice were colonized diet either antibiotic treated AB fat untreated control CT microbiota. Die role of environmental factors in modulating gut microbiota composition has been strongly indicated by the observation that co-habiting parents share depend more similar microbiota high compared with individuals from other families[ 23 ]. However, in obesity current study, body weights increased equally and were similar over time tlr5 wild type tlr5 TLR5KO2 groups diet fed normal chow.

The gut microbiota is involved in many aspects of host physiology but its role in body weight and glucose metabolism remains unclear. Here we studied the compositional changes of gut microbiota in diet-induced obesity mice that were conventionally raised or received microbiota transplantation. In conventional mice, the diversity of the faecal microbiota was weakly associated with 1 st week weight gain but transferring the microbiota of mice with contrasting weight gain to germfree mice did not change obesity development or feed efficiency of recipients regardless whether the microbiota was taken before or after 10 weeks high fat HF feeding.
