In ice, molecules are strongly bonded to each other, and
they form a rigid solid. When heat is added, water is formed. The bond between
molecules is broken and their state is changed. To stay in this changed state,
the temperature of the water needs to be kept just warm enough.
To lose weight, you also need to break a bond—between you
and overeating. This puts you in a new state—of mind. To maintain this new
state, the behaviors you changed need to be kept up just enough.
