False. ‘Fat free’ doesn’t mean ‘kilojoule free’. Although low fat or fat free foods are often lower in kilojoules than full-fat equivalents, many contain added sugar or starch thickeners to improve flavor and texture after the fat has been removed. These ingredients add kilojoules. So sweets like jelly babies may be fat-free, but they still pack a kilojoule punch at 1 600kJ per l00g of product – the same as six slices of bread.
