The phrasal verb "cut down on" is commonly used in both informal and semi-formal speech, though it is often avoided in more formal contexts where a more precise term might be used, such as "reduce" or "decrease." Generally, it is employed when discussing the reduction of something, typically in reference to quantities, frequency, or intensity. For instance, one might "cut down on sugar" or "cut down on expenses." It implies a deliberate effort to lessen the use or consumption of something, often due to health, financial, or environmental reasons. Notably, while "cut down on" is very common in conversation and can appear in both spoken and written communication, its informal tone makes it less suitable for formal reports or academic writing. The phrase suggests an act of moderation or restraint rather than complete removal, making it versatile for discussions about changing habits or practices.
