The Men Who Made Us Fat - Season 1

Around the world, obesity levels are rising. More people are now overweight than undernourished. Two thirds of British adults are overweight and one in four of us is classified as obese. In the first of thisthree-part series, Jacques Peretti traces those responsible for revolutionising our eating habits, to find out how decisions made in America 40 years ago influence the way we eat now.

Jacques Peretti investigates how the concept of 'supersizing' changed our eating habits forever. How did we - once a nation of moderate eaters - start to want more?

Speaking to Mike Donahue, former McDonalds Vice President, Peretti explores the history behind the idea of supersizing. 40 years ago, McDonalds hired David Wallerstein, a former cinema manager who had introduced the idea of selling larger popcorn servings in his Chicago cinema. Wallerstein realised that people would eat more but they did not like the idea of appearing gluttonous by going back for seconds. By increasing the portion sizes and the cost, he could sell more food. In 1972, he introduced the idea to McDonalds and their first large fries went on sale.

Jacques Peretti examines assumptions about what is and is not healthy. He also looks at how product marketing can seduce consumers into buying supposed 'healthy foods' such as muesli and juices, both of which can be high in sugar.

He speaks with Simon Wright, an 'organic consultant' for Sainsbury's in the 1990s, who explains how the food industry cashed in on the public's concerns around salmonella, BSE and GM crops. By 1999 the organic industry was worth over £605M, a rise of 232% within two years.

How did the mainstream food producers compete? Peretti speaks with Kath Dalmeny, former policy director at the Food Commission, who explains some of the marketing strategies used by mainstream food producers to keep our custom.
