This latest offering from David Gillespie explodes the myths about diet, exercise and vitamin supplements, examining the latest scientific evidence and exposing the role the multibillion-dollar food, health and diet industries have played in promoting the health messages we follow or feel guilty about not following. Eat less, exercise more, eat less saturated fat, eat more polyunsaturated oils, take vitamin and omega-3 fatty acid supplements - this is what we are told (and the statistics even show it is what we do) - but the rates of obesity, heart disease, type 2 diabetes, dementia and cancer have never been higher. The real culprits, Gillespie says, are sugar and polyunsaturated oils. He outlines a plan to avoid them without missing out or 'dieting', and to improve our health, happiness and life-expectancy.

David Gillespie is a recovering corporate lawyer, co-founder of a successful software company and consultant to the IT industry. He is also the father of six young children (including one set of twins). With such a lot of extra time on his hands, and 40 extra kilos on his waistline, he set out to investigate why he, like so many in his generation, was fat. He deciphered the latest medical findings on diet and weight gain and what he found was chilling. Being fat was the least of his problems. He needed to stop poisoning himself.
