In the prior blog I reported on the physical changes in 32 men in the Minnesota Study reported by Ancel Keys. Now I will report the psychological changes noted by Keys.
These changes include:
- fatigue, apathy, and feelings of sadness, gloominess, feeling blah, depressed.
- concentration, alertness, self-discipline and comprehension decreased.
- irritability, moodiness, tension, anxiety, and restlessness increased.
- spontaneous activity and interests declined.
- reduced ambition, interests and pleasure.
- feeling ineffective.
- self-perceptions were skewed to the negative and performance declined in a variety of pursuits.
- reduced libido
- reduced self-care
- some violence
- sensitivity to noise
- poorer work performance.
Clearly there are prominent changes in emotional modulation with an overall depression in a number of functions.
