Most of us would say that obesity is a consequence of eating too much, exercising too little, and an unfortunate combination of genes, but things might not be so simple. A new study suggests that the microbes in our gut can influence how we put on weight, and because these organisms can move from one person to another, it might be possible to literally ‘catch’ obesity from others.
For the first time, scientists in the UK have shown that a third of the spores produced by bacteria in the human gut can survive out in the open air. This implies that the people we come into close contact with could influence our own gut bacteria as these spores spread through the air.
