Cutting is the one phase everyone starts and half abandon by week six — and of those who finish, many regain most of it in a month. The failure points are predictable, which means they are plannable. Here is the complete arc.
Phase 0: pick the honest rate
0.5 kg/week (TDEE − 500 kcal) is the default because it preserves muscle, training quality, and mood. Above 1% of bodyweight per week, muscle loss risk climbs sharply once you are under ~20% body fat. If the timeline math says your cut needs 20+ weeks at that rate, plan diet breaks — don't double the deficit.
Phase 1: weeks 1–2 — the calibration
The first two weeks lie. Glycogen drops with its water (−1 to −2.5 kg instantly), sodium falls, and the scale's joy is fake. Judge nothing before week three. From there, weigh daily and use weekly averages: target the rate, ignore the daily noise. Hunger also peaks around weeks 2–4 and partially adapts — another reason not to react to early discomfort by slashing calories further.
Phase 2: the stall protocol
Every cut stalls — typically weeks 6–10 — for three stacked reasons: adaptation (TDEE fell), NEAT collapse (unconscious movement drops in deficit, sometimes by 300–400 kcal), and intake creep (portions grow; logging honesty decays). The response, in order:
- Audit logging for one week — the food scale returns more deficit than any new diet trick.
- Add 2,000 daily steps — restores NEAT without recovery cost.
- Then, only if needed, −100–200 kcal. Never −500; that is how muscle loss and binge risk start.
Phase 3: the maintenance break
Every 8–12 weeks of deficit, take 1–2 weeks at maintenance (recompute TDEE at the new weight — it has fallen). Physiologically this restores leptin, thyroid, and NEAT partially; psychologically it is the pressure valve that makes the next block possible. A planned break is not a failed diet — it is the structure that finishes one.
Phase 4: the reverse diet nobody plans
Ending the cut at 1,900 kcal and "celebrating" at 3,000 guarantees a +3–4 kg overshoot: adaptation persists, hunger is primed, and NEAT has not recovered. Reverse instead: +100–150 kcal per week until you reach the new TDEE, watching the weekly average stay flat. Then hold at maintenance 4–8 weeks before deciding on a bulk. The cut's success is judged three months after it ends, not at the final weigh-in.
The plate-level details that carry it
- Protein high and even (use the split calculator) — satiety and muscle in one lever.
- Fiber 25–38 g and volume foods — hunger is a volume problem before it is a calorie problem.
- Keep lifting heavy. The training stimulus is the "keep this muscle" signal; light high-rep pump work tells your body the muscle is optional.
- Sleep 7–9 hours. Restricted sleep shifts weight loss from fat toward muscle and doubles hunger hormones — the most underrated cut variable.
Run the arc as designed and the cut becomes boring — which is exactly the point.
