We all have trillions of bacteria living on and inside our bodies – but how can they affect weight loss, diabetes and even your mood.

 In this interview with Dr Lesley Hoyles from Imperial College in London, you’ll hear all about the gut microbiome – the collection of bacteria and other micro organisms that co-exist with us in our guts, and influence so many aspects of our health.

The balance of bugs is affected by countless things, from how you were born, to the antibiotics you’ve taken, and whether you eat live yogurt or onions.

Lesley gives us a tour of research into the gut microbiome and how it’s set to change the medical world.  Plus we talk about getting dirty in childhood, weight gain in farm animals, and the one transplant you don’t want to search for on YouTube…

Lesley runs the Bugs in your Guts Twitter account - well worth following - and the other ones she recommends for great information about microbiology and health are:
