Adherence
Manipulating energy density does not significantly alter the total amount of food consumed (in grams), meaning volume intake remains constant.
Do not worry about shrinking your portions. When you lower the energy density of your food (e.g., by adding vegetables), you can eat the same amount of food by weight. This helps maintain satiety and makes the diet easier to follow long-term.
GoodSupportsHIGH confidence
Dietary ED did not affect the amount of food intake.
Why this rating
Based on meta-analysis of 26 studies, though heterogeneity was moderate.
