New studies show that losing weight may be harder than you think. A high fat, high-sugar diet alters the composition of bacteria in your intestines. This bacteria makes it easier to gain weight and harder to lose it.
According to the new journal Science Translational Medicine, research in mice shows that this changeover can happen as quick as 24 hours.
There are many factors to weight gain, including genetics, physical activity, the environment, and food choices. Dr. Jeffrey I. Gordon of Washington University in St. Louis has taken the lead on accumulation of evidence that puts bacteria in the intestines on the list of factors.
Why does this bacteria form? Simple, the human body needs such bacteria to help convert otherwise indigestible foods into digestible form.
This bacteria falls into two major divisions, the Firmicutes and the Bacteroidetes. Previous research had shown that obese mice had higher levels of Firmicutes, and lean ones had more Bacteroidetes.
