Adherence
Modifying the composition of existing foods (e.g., reducing energy density) is a faster and more feasible way to change population dietary intake than attempting to change eating behaviors or beliefs directly.
If you want to improve your diet, modify the foods you already eat (e.g., lower fat/sugar versions) rather than trying to learn entirely new recipes or habits. This leverages existing habits and requires less cognitive effort.
GoodSupportsHIGH confidence
The accumulated experience from nutrition education and health promotion research strongly suggests that it is faster and more feasible to change food (Keenen et al. 1996; Sigman-Grant, 1997).
