A new study from the Institute for Systems Biology compared people who lost 1% or more of their weight each month on a weight loss diet, compared with those whose weight didn’t budge–finding that the groups had different microbial DNA and bacteria in their microbiome. Those that lost weight had microbial DNA that allowed bacteria (especially Prevotella) to grow fast (these bacteria ate more sugar/nutrients before the body could absorb them), while the weight-loss-resistant group had gut enzymes better at breaking down starches/fiber into sugars. More evidence that altering the microbiome is a path to weight loss.
