A countdown show looking at the shocking truth behind what we eat and the often dangerous and misguided methods we adopt in order to lose weight. Scientists, industry experts and exponents discuss the pros and cons of fad diets, 'healthy' foods and extreme exercise regimes. We all know about the benefits of exercise, good diet, looking good and living a healthy lifestyle, but most of the things that are good for us can bring side-effects that are precisely the opposite. Incontinence, infertility, infected genitalia, energy drink madness, hip replacements and even death are commonplace among the beautiful people – as are botched surgeries, extremely dangerous self-harming diets and bizarre exercise programmes.

As new parents can attest, children develop so much in the first year of their life it's hard to keep up. From the moment they draw their initial breath - itself an incredibly complicated biological feat - to their first steps, it's a year of remarkable development. In The Science of Babies, Nat Geo explores the amazing biomechanical benchmarks achieved in the first 12 months of human life. Using CGI, fMRI and other tools, viewers can watch as a baby's lungs draw breath for the first time, and can witness the heart grow exponentially in order to power this incredible developing creature. Perhaps even more fascinating is the manner in which the neurosynapses develop, creating the essence of what will become a new personality and intellect. This film explores the amazing mechanics behind the initial milestones in a human infant's life, and even compares them to babies of other species. Beyond simply being a beautiful film to watch, the technology that Nat Geo uses to help tell the tale is remarkable.
