Final answer:
In the Minnesota Starvation study, the men reduced their energy expenditure by decreasing physical activity levels, limiting calorie intake, and losing body mass.
Step-by-step explanation:
In the Minnesota Starvation study, the men reduced their energy expenditure in several ways:
- They decreased their physical activity levels.
- They limited their calorie intake to mimic conditions of starvation.
- They lost body mass, which resulted in a decrease in metabolism.
These measures were taken to simulate the effects of starvation and study its physiological and psychological impacts.
