A cut

Also known as

calorie deficit · cutting · shred · 500 calorie deficit · fat loss phase

Community talk may be wrong. Not medical, training, or diet advice. Sharp pain, fainting, or disordered-eating concerns need a clinician.

In brief

A cut is a period of eating less energy than the body uses, usually discussed in lifting circles as a fat-loss phase.

The common picture
About 500 kcal underr/loseit still repeats this as ~a pound a week if the number is real.
Protein and lifting staySo the weight that leaves is not all strength.
Weeks, not a weekendThe whoosh after a stall is common talk.
Steps stayNEAT dies on a cut unless they protect walks.
An end date or an end lookA cut without an exit becomes a personality.
Rate discussed: about 0.5–1% of body weight per weekThis is the range in the careful-tracking accounts, distinct from the calorie-deficit estimate.

People compare how a cut fits around training, hunger and ordinary meals, and how they decide when to return to maintenance.

Good to know. 1200-calorie floors copied off TikTok. Eating back every wearable calorie. A cut with no lifting.

What people say

  • The job: A season of less, not a personality.
  • r/loseit 2026 stall threads: “I ate 500 under and nothing moved” usually means the 500 was fiction or they ate the steps back.
  • ACSM 2026 still lists exercise for weight management as a top industry trend. Exercise without a deficit is a different story.
  • Wearables overestimate burn. Eating every “credit” is a classic stall.
  • 1200 is not a universal floor. It is a TikTok number that is too low for a lot of adults.
  • Whoosh: a stall, then a sudden drop after they eat more salt/carbs or just wait. Folk physics, common diary.
  • Lifting on a cut is how they keep the look they wanted the cut for.
  • GLP-1 cuts belong with the drug card on STUDresearch plus Self keep-muscle.
  • Women’s cycle stalls are a weekly thread. They zoom out to months.
  • Reverse diet is how people exit. Later card.
  • It is not “shredded in 30 days.” Those ads are the watch-for.

How people do it

  • Pick a number they can eat, not a dare.
  • Keep the lifting week. Adds may pause. Holding load is a win.
  • Do not eat back every watch calorie.
  • Weigh 2–3× a week or weekly averages. Daily panic is optional.
  • Keep protein and a boring lunch.
  • Protect steps. The couch is a hidden surplus.
  • When they reach the goal or the mood breaks: they stop. Reverse or maintenance.

Amounts people use

  • Deficit people quote: about 500 kcal.
  • Rate talk: about 0.5–1% bodyweight / week in careful rooms.
  • Time: weeks to a few months, then they stop.
  • Protein: they keep the Self target as best they can.
  • Steps: many try to hold 7–10k so the deficit is real.

How people keep it

  • A boring lunch they can repeat.
  • A lift log so the mirror is not the only judge.
  • A date they will stop even if they are not “done.”
  • Social food planned, not surprised.
  • Sleep. Short nights make the deficit feel like a crisis.

How it may feel

  • Two weeks: fine, even smug.
  • Then: hungry, cold, moody. Libido and patience dip in a lot of diaries.
  • A stall: they want to slash calories. Forums say wait or check steps.
  • A whoosh: they feel vindicated and immediately overeat. Classic.
  • Too-deep cut: they are wrecked in the gym and still not “shredded.”
  • The last two weeks: they should have stopped already.

How long

  • A season. Not forever.
  • Shorter if they started lean. Longer if they have more to lose — still with breaks.
  • Diet breaks / reverse exist because forever cuts fail.
  • After: maintenance or a lean bulk. Not another cut Monday.

The longer notes

  • Disordered patterns are a person and a clinician, not a forum macro.
  • Lean vs dirty bulk is the opposite season.
  • Fasted cardio is a ritual some people add. It is not required. See that card.
  • Research fat-burners are a different product. This card is the deficit.
  • Kids / pregnancy / medical conditions: not a forum cut.

More from the community

A cut discussion can begin with competing priorities rather than a target weight. In an August 2026 bodybuilding thread, a lifter liked how training was going during a bulk but disliked becoming softer; replies proposed either maintenance or a mini-cut. The disagreement was partly about whether to interrupt a satisfying training phase, not simply how to lose weight fastest.Source 1
