Definition of «fast»

"Fast" refers to a period of intentional abstinence from food, often discussed in online communities focused on fitness, weight loss, or "pro-ana" subcultures. While it has traditional religious and medical meanings, in contemporary internet slang, it is frequently used to describe a self-imposed challenge to see how long one can go without eating. It is often discussed alongside "counting calories" or "binging" as part of a structured, though sometimes unhealthy, lifestyle regimen. Users may track their "fasts" using apps and share their progress or "trips" to stay motivated.
