Are intervention effects maintained for the diet change group?
Overall, this indicates that intervention effects were maintained for the diet change group at 3-month follow up. Of the 33 individuals who were able to be contacted, 7 (21.2%) said they had maintained the diet, 19 (57.6%) reported they had maintained some aspects of the diet and 7 (21.2%) reported they had not maintained the diet.
Can a low-cost diet intervention improve diet adherence among young adults?
The fact that this relatively low-cost intervention can result in a population of young adults adhering to diet recommendations is very promising. Furthermore, it is important to consider that participants in the current study did not need to adhere strictly to the diet recommendations to derive benefit.
Is there a randomized controlled trial of diet in young adults?
To our knowledge, there is only one other randomized controlled trial of a diet intervention in young adults, which included mood as an outcome.
