The researchers have not yet done a head-to-head comparison of different interventions, but one is planned for the future. The effectiveness of a strategy will depend on how well it can be implemented and whether the appropriate sub- populations are targeted for example high consumers of sugar-sweetened beverages. Key discrete strategies, identified from the literature, to reformulate or reduce discretionary foods would in theory have small to moderate impacts on the diet quality of the overall population and a subset of those who self-report having diabetes. The impact of these strategies in combination, or for sub-populations with proportionally higher discretionary food intake may be more substantial. While it is clear that most overweight individuals would benefit from consuming fewer calories, diet quality goes beyond total calories, and simply reducing food from the diet may result in nutrient deficits, and is usually not sustainable since people can experience hunger and subsequently reduce compliance. Replacing some discretionary choices with less energy-dense core foods is likely to be a more sustainable option to improve diet quality and reduce daily calorie intake without resulting in increased hunger.
