See, I'm not lazy!

It's the MICROBES, man...

US scientists have discovered that "gut microbes" - bacteria that live in our digestive tract - could be powerful clues to the cause and treatment of obesity.

This remarkable news was published in Nature this week and conducted at Washington University School of Medicine in St. Louis.

The clue lies in the relative abundance of two major families of intestinal bacteria: Firmicutes and Bacteroidetes. These make up 90 per cent of the bacteria in the gut of humans, and, coincidentally, white mice.

Researchers in the first of two parallel studies found that as obese people lose weight, the balance between the Firmicutes and the Bacteroidetes changes - the latter increasing in abundance as an overweight person gets slimmer. (It would seem that the microbes ending in "cute" are perhaps not as lovable as their name implies!).
