Receiving a handful of microorganisms that inhabit the digestive system of lean people , obese individuals could lose weight. This is clear from the work of a group of scientists from the universities of Washington, Colorado and Stanford, all of them in the United States, that after implanting bacteria from the human intestine in mice they have managed to alter their metabolism and accelerate their metabolic rate, causing a loss of weight.
The researchers also showed that by extracting fecal bacteria from the stools of adult twins in which one sister was obese and the other thin, and transplanting the germs into rodents, mice with microbes from obese individuals gained more weight than those receiving bacteria from subjects. thin. "In other words, weight gain can be transmitted from humans to mice through their digestive microbes ," concludes Rob Knight, co-author of the study published in the journal Science, which could lead to a new remedy for overweight and obesity. .
The content of the diet also influences the effect of this therapy. Specifically, in the experiment, the scientists observed that the colonization process did not take place when the animals were fed a diet low in fiber and high in carbohydrates and fat .
