The lost treasure of the Incas.
You get the idea.
The dictionary lists these definitions for loss:
- Detriment, disadvantage, or deprivation from failure to keep, have, or get: to bear the loss of a robbery.
- An amount or number lost: The loss of life increased each day.
- The state of being deprived of or of being without something that one has had: the loss of old friends.
- Death, or the fact of being dead: to mourn the loss of a grandparent.
Maybe that's one of the reasons why so many gain weight back after they've shed it: Somehow the subconscious mind (which takes things very literally) takes the term "weight loss" as a literal loss - a deprivation - and undermines our efforts in trying to regain that which is lost.
