Abstract

Abstract: Young residents of the European North of Russia with normal body weight ( n = 66) were divided into three groups, SJL ≤ 1 h, 1 < SJL ≤ 2 h, and SJL > 2 h, using the Munich ChronoType Questionnaire. Participants consumed a breakfast consisting of pizza ad libitum and rated their appetite sensations using visual analog scales. Participants in three SJL groups consumed the same amount of the ad libitum meal and reported similar levels of satiety and fullness right after food intake (intra-meal satiation). However, participants with SJL > 2 h were found to feel significantly hungrier in comparison with participants with SJL ≤ 1 h. In addition, participants with SJL > 2 h reported a diminished satisfaction with food consumption (inter-meal satiety) during 120 min after test breakfast. Thus, the study demonstrates that SJL appears to be associated with disturbance of appetite regulation in young northerners with normal body weight.
