There is M-: (setq olivetti-body-width N), which has the same effect,
but I guess you mean that you've set `olivetti-body-width' and it
appears to have no effect, in which case you need to trigger
`window-configuration-change-hook' by changing or resizing the window
somehow. Even just switching away to another buffer and back will
trigger this, or you could run
(run-hooks 'window-configuration-change-hook)

Or, if you mean something that gives a +/- increment akin to `C-x }', no
sorry, but good suggestion.
