Which of the following tracking methods requires training, use of estimates, and nonjudgmental feedback?

A) Journaling
B) Checking off
C) Electronic monitoring
D) Using art
E) Empty bowl

Journaling requires training in terms of knowing what information to track, use of estimates for portion sizes and nutrient content, and involves nonjudgmental feedback as it is a means of self-reflection and analysis. Checking off and electronic monitoring may also require training but do not involve as much estimation or personal reflection as journaling. Using art and the empty bowl method are not tracking methods and do not involve training or estimation.
