...microbes, which live and thrive in the human intestinal tract and colon and most of which survive without oxygen. These microbes perform an enormous range of vital functions, including helping regulate the calories the body obtains from food and stores as fat. In other words, they may help regulate weight. And a new study published on Nov. 12 in Science Translational Medicine suggests that the particular type and balance of bugs you harbor in your gut may help push your body toward either obesity or leanness and that these microbe populations might even be manipulated to potentially change your weight...
...calories in), the more fat you gain - an equation that may be heavily influenced by your particular genes. But scientists have long known that these three factors do not adequately explain every case of obesity, and now researchers are discovering increasingly convincing evidence of another important contributor to body weight, one that until recently has been almost completely ignored: the bacteria that live in your...
...Louis, Mo., who conducted the previous research, experimented again with mice for the new paper. This time, however, he and his team used human microbiota to colonize mouse guts and then fed the rodents the equivalents of typical human diets to see how their microbes - and their weight - changed...
That diversity and its impact came into plain view when the researchers started experimenting with the rodents' diet. When one group of mice was fed a typical Western diet, high in fat and sugars, they tended to gain weight and grow more Firmicutes gut bacteria and fewer Bacteroidetes. In mice given a low-fat plant-based chow, the distribution of the two groups of bugs flipped and the animals remained lean. It's not clear whether the balance of gut bugs causes weight gain or is a result of it, but the findings suggest that a "gut profile" could potentially...
...better manage the energy it has. There was no need for so much of the populous southern and central Brazil to be taking energy from Itaipu at the same time, Schechtman says. "The whole point of the grid system is to provide balance so that all the weight is not hanging from one line," he says. "If you have lots of lines and one breaks, the others pick up the strain. What I want to hear from the government is why so much pressure was on Itaipu." He is not the only one. The government has a lot of explaining...
