In the US, 80% of girls have been on a diet by the time they're 10 years old. In this honest, raw talk, neuroscientist Sandra Aamodt uses her personal story to frame an important lesson about how our brains manage our bodies, as she explores the science behind why dieting not only doesn't work, but is likely to do more harm than good.

She suggests ideas for how to live a less diet-obsessed life, intuitively and explores "mindful eating" which she says is to "eat when you are hungry and stop when you are full".

This 12 minute talk from TED.com is well worth a watch.
