When a host experiences increased energy demands, do the gut microbiota help maintain homeostasis? In a recent Cell article, Chevalier, et al. showed that mice who were exposed to cold temperatures experienced a shift in microbiota composition. Transplanting this 'cold microbiota' into germ-free mice resulted in increased insulin sensitivity and white fat browning, with increased energy expenditure and fat loss.…

Liping Zhao and colleagues, in their recent paper on a dietary intervention for simple and genetic obesity, discussed evidence for the existence of gut microbiota 'guilds': bacterial genomes within the gut ecosystem that responded to the dietary intervention as a group. Zhao further explains to GMFH editors, "Guilds are functional groups formed by different species in an ecosystem. Members in…

Previous studies have shown both genetics and the gut microbiome influence a host's metabolic phenotype. By analyzing the fecal samples of twins, researchers found that the abundance of many microbial taxa in the gut were influenced by genetics. The family Christensenellaceae was the most heritable, and co-occurred with a group of other microorganisms. This heritable group was associated with a…

His main interests are gut functions in health and disease, including functional and inflammatory bowel disorders, the role of the gut microbiota, regulation of eating and food intake and its disorders, of nausea, vomiting and motion sickness, and the psychophysiology and neurobiology of the placebo response, with specific emphasis on age and gender contributions. He has published more than 170 original data paper in scientific, peer-reviewed journals, and more than 250 book chapters and review articles. He is board member/treasurer of the European Society of Neurogastroenterology and Motility and of the German Society of Neurogastroenterology and Motility, and has served as reviewer for many international journals and grant agencies.

A recent study lent insight into the role of the microbiota in both diet-related and genetic obesity in humans. This Chinese study, led by Prof. Liping Zhao, Prof. Aihua Yin, and Prof. Huiru Tang, involved 17 children with Prader-Willi syndrome (PWS) -- the most common genetic cause of morbid obesity in children -- and 21 with simple (diet-induced) obesity. The…

Tremaroli et al. reported that bariatric surgery for obesity, whether gastric bypass or vertical banded gastroplasty, induced a significant and sustained change in the gut microbiome of 14 women for at least a decade.   The researchers observed that both surgical procedures induced similar and durable changes, and were found not dependent on body mass index. Among the changes in…

Prebiotics and probiotics are food components that directly target the gut microbiota. This recent human study investigated their effects on gut microbiota and metabolic risk markers in obesity. In this trial, researchers tested the probiotic Lactobacillus paracasei, which has been associated with a healthy metabolic profile in previous research. They also tested flaxseed -- composed of 30% dietary fibres, including…

Obesity and type 2 diabetes mellitus (T2DM) are complex chronic diseases with rapidly growing prevalence across the world. Human studies have found that both genetic and environmental factors contribute to T2DM; the clearest lifestyle factors are high caloric intake and low physical activity. The mechanisms by which human T2DM arises is still unclear, but obesity, insulin resistance and ß-cell dysfunction…

Scientists aren't clear on the exact relationship between the Firmicutes to Bacteroides/Prevotella (F:B) ratio, fecal short-chain fatty acid (SCFA) levels, and obesity. This observational human study analyzed 3-day dietary intakes, physical activity levels, body mass index, fecal microbiota, and SCFAs in both lean and overweight/obese research participants (n=94).   They found that diet and physical activity levels were similar between…
