Talk Synopsis: Are Microbes Making You Fat?

Atkins, SlimFast, low-fat, high-protein, 5:2, and plain old cabbage soup – how many of these diets have you tried? And are you now slim? Despite over seven decades of popular diets, nutritional science, and exercise videos, six out of ten of us are still overweight. What’s more, obesity is spreading like an infectious disease, catching us younger and making us fatter.

But what if it’s not all about food and exercise? What if being fat can be transferred from one person to another via their gut microbes? Alanna Collen unravels the incredible role that the body’s microbes play in controlling appetite and regulating body weight.
