feeding behavior of humans.

Abstract
The role of protein, carbohydrate and fat ingestion on self-rated mood and
subsequent food intake was investigated using self-reports of spontaneous
food intake. Eight male and 30 female undergraduate students were instructed
to list everything they ate, when they ate it, and their mood at the time of
ingestion. They were asked to make these entries in a diary throughout a nine
day period. Mood was rated at the beginning of each meal on three seven point
scales; elated-depressed, tired-energetic, and anxious-tranquil. The amount
of protein, carbohydrate, and fat as well as the total amount of food energy
in each meal and the intermeal intervals (IMIs) prior to and following the
meals were calculated with a computerized analysis. The energy content and
the amount of each of the macronutrients contained in the stomach at the
beginning and end of each meal was estimated with a mathematical model. These
data were then intercorrelated using bivariate and multivariate techniques.
Momentary self-rated mood was not found to be related to prior macronutrient
intake nor was it predictive of subsequent intake. Long term macronutrient
intake, averaged over the nine recording days, was found to be related to the
averaged mood of the subjects. Although no significant relationships were
found between the absolute amounts of the macronutrients ingested and mood,
significant correlations were found between the proportion of each
macronutrient in the diet and the overall self-rated mood.(ABSTRACT TRUNCATED
