Summary  Obesity is the leading public health problem in the 21st century, both in its own right and as a risk factor for many chronic diseases, and it occurs when there is an imbalance between energy intake and expenditure. This review will focus on the role of energy density, protein, fat, carbohydrate, fruit and vegetables, and alcohol in weight loss and weight management, and the biochemical, social and behavioural factors that influence dietary intake.
