How Much Energy Can I Burn by Thinking?

BBC World Service - CrowdScience, How Much Energy Can I Burn by Thinking?

Could we lose weight just by exercising our brain?

CrowdScience joins listeners from around the world to discover how effort and energy affect our lives.

Wouldn’t it be great if you could lose weight and stay fit just by exercising your brain?  Trouble is everything takes so much effort - from burning off excess weight to powering our cars.  But why?

Presenter Marnie Chesterton rummages through the CrowdScience inbox to tackle all your energy-expending queries. Is the entire universe spinning?  How much energy do we expend when sleeping? Can I think myself thinner?  Scientists Helen Czerski, Andrew Pontzen and Andrea Sella join listeners from around the world to discover how effort and energy affect our lives.
