Sir, Your article 'Calorie counting won't work, warns industry' (8 October) suggests there is an "IGD-spearheaded strategy" concerning the energy density of foods. This is not really the case.

IGD works with the food and grocery industry to develop guidance and best practice on diet, nutrition and health. We recently published a report on 'The role of energy density in helping consumers make healthy choices'. It provides food businesses with information on energy density and its role in achieving energy balance.

The report makes no claim that low-calorie foods were a major turn-off for customers and that people would be better in some cases eating higher calorie portions that satisfied their appetites. This part of the article was inaccurate.
