To find out why I was having an increasingly difficult time adjusting, I reached out to Ben Michaelis, a psychologist and author of “Your Next Big Thing: Ten Small Steps to Get Moving and Get Happy.”
Michaelis chalked up my feelings to a concept known as “hedonic adaptation,” the tendency of humans to adapt to their circumstances, no matter how good or bad they are. In other words, I had become used to my premium fitness lifestyle, so cutting it made me feel deprived—and resentful.
“We get used to things at a certain level, and as human beings sensitive to loss, the idea that you have to give up something you achieved can feel like you’re going backwards in life,” Michaelis explained. “It can lead to some negative feelings.”
