Background: Hunger has often components that are conditioned by time, social behavior and sight of food. Blood glucose concentration (BG) is a biomarker of current energy availability and of hunger.
Objectives: Investigating whether energy per meal reduction may allow BG to fall to low levels, when feeding behavior is (mostly) unconditioned and can be recognized.
Methods: Subjects of experimental group (trained; n = 80) were trained to ignore meal times and to pay attention to their earliest sensations of hunger or discomfort, so to measure glucose (blood glucose,BG) with glucometer for two weeks. The control group was untrained; n = 78). After 7-week, all subjects were asked to estimate their preprandial
