Vacation Mode
When I'm at home I log everything I eat, rather meticulously. I cook nearly every meal I eat, weighing all the ingredients to the gram--so I can manage my weight. And thus far it has been an incredibly effective tool.
Now that I'm at my target weight I intend to continue doing this.
However, when my wife and I travel, I'd rather set the system to 'vacation mode.' That is, indicate that (say) for the next two weeks I'm not logging my meals, mostly because we're eating out and it's too cumbersome to log meals. And because I'd rather put down the burden of logging while on vacation.
And once I return, vacation mode turns off and I resume normal logging.
