Splitting up a larger unit into smaller units can create additional decision moments for a person. Instead of continuing with something, a person has to make an active choice to open or start an additional unit. Being forced to make that active choice may make it more likely that they make a choice to stop that behavior.
To encourage someone to consume less of something, break it up into units that are split apart.
For example, breaking up a bag of cookies into smaller bags creates a decision moment when a person has to make an active choice to open another packet of food.
Netflix allows you to change the default setting of having a new video automatically play after you finish a video. This creates a moment when you decide to continue watching or do something else.
Creating specifically timed periods for a behavior, for example an app that closes automatically after 30 minutes. The individual can reopen the app so choices aren’t being eliminated, but they have to actively choose to reopen.
