Cutting Without Losing the Bar
The fear that stops most lifters cutting is losing strength. It is a reasonable fear — some loss of absolute strength during a deficit is normal. But the amount is usually smaller than expected, and a fair bit of what looks like loss on paper is not loss at all once bodyweight is accounted for.
The measurement problem first
Suppose you squat 170kg at 83kg bodyweight, cut to 75kg, and your squat comes back at 163kg. Seven kilos gone. Most people read that as a failed cut.
Run both through the Wilks Calculator and a different picture appears. At 83kg the coefficient is 0.6675, so 170kg scores 113.47. At 75kg the coefficient rises to 0.7126, so 163kg scores 116.15. The score went up. You are producing very nearly the same force from eight kilos less body, which is exactly what a well-run cut is supposed to achieve.
This is the main reason to compute Wilks at all. During bodyweight change the raw number on the bar is a misleading progress metric, and the scaled one is not.
What the numbers look like
An 80kg lifter training moderately, cutting, gets roughly 2,312 kcal, 160g protein, 274g carbohydrate and 64g fat from the macro calculator. The protein figure is identical to what the same lifter would get while gaining — it is scaled to bodyweight, not to calories, and the case for holding it steady is strongest precisely when energy is short.
A heavier lifter at 95kg on lighter activity lands near 2,503 kcal with 190g protein. The pattern holds: calories move with the goal, protein does not.
What to change in training, and what not to
The instinct in a deficit is to train more — more sets, more sessions, more conditioning. This is usually the wrong direction, and it is where cuts go wrong.
- Keep the intensity. The weight on the bar is the signal that tells your body to hold onto muscle. Keep training near the percentages you were using; the percentage calculator will tell you what those are.
- Let volume come down. Recovery is compromised in a deficit and total work is what your capacity limits. A tonnage log that drifts down 10–20% during a cut is expected. Do not fight it.
- Expect flat weeks. Progression usually stalls in a deficit. Maintaining the bar weight through a cut is a success, not a plateau.
- Do not re-test your max mid-cut. You will get a number depressed by fatigue and low glycogen, and then build the rest of the block on it. Estimate from a submaximal set with the 1RM calculator if you need a figure.
Pace
Roughly 0.5–1% of bodyweight a week is the range most lifters can sustain without training falling apart. For an 80kg lifter that is 400–800g a week. Faster is possible and generally costs more: worse sessions, worse recovery, and a larger share of the loss coming from somewhere other than fat.
Judge it on a weekly trend rather than daily readings. Day-to-day bodyweight moves several hundred grams on water and food volume alone, and reacting to that noise is how people end up cutting far harder than they meant to.
When to stop
Some honest signals that a cut has run long enough: sessions that used to feel routine now feel heavy at the same percentages, sleep getting worse, persistent irritability, and a tonnage log that keeps falling after you have already reduced it deliberately.
None of those is a moral failure or a sign you need more discipline. They are the ordinary cost of running an energy deficit, and the correct response to accumulating them is to eat at maintenance for a while.
As with the rest of this: an estimate is a starting point, the scale and the logbook are the evidence, and anything involving a medical condition or a specific clinical goal belongs with a registered dietitian rather than a calculator.
Water, glycogen, and why the scale lies for a fortnight
Reduce carbohydrate intake and bodyweight drops quickly for reasons that have little to do with fat. Muscle glycogen binds water — roughly three grams of water per gram of glycogen — so depleting stores sheds a noticeable amount of weight in the first week or two.
This produces two predictable illusions. Early in a cut, progress looks miraculous. Later, when the glycogen loss has finished and only fat loss remains, progress looks like it has stalled even though nothing has changed.
The same mechanism runs in reverse and explains a common panic: eat one high-carbohydrate meal after weeks of restriction and the scale can jump a kilo or more overnight. That is water and food in transit, not fat gained. It is arithmetically impossible for a single meal to add a kilo of fat.
The practical response is to judge everything on a weekly average and to ignore the first fortnight of any cut as a measure of fat loss. It is real weight, it is just not the thing you were trying to lose.
Strength in a deficit is partly a glycogen story too
Some of the strength you appear to lose while cutting is not lost capacity. Depleted glycogen affects how a set feels, particularly in the higher rep ranges, and low-carbohydrate days often produce sessions that feel heavy at weights that were routine.
Two useful consequences. First, do not re-estimate your max on a low-carbohydrate day and then rebuild your programme on the result — you will lock in a number depressed by fuel rather than by strength. Second, if a cut is going long, placing your higher-carbohydrate days on your heaviest training days costs nothing and makes those sessions considerably more productive.
Refeeds, diet breaks, and knowing which you need
These get conflated and they do different jobs.
A refeed is a day or two at higher carbohydrate, roughly at maintenance calories. It restores glycogen and generally makes training feel normal again. Useful before a heavy week.
A diet break is one to two weeks at genuine maintenance. It addresses the accumulated cost of a long deficit — sleep, mood, and the general grind — rather than just fuel. If you have been in a deficit for two or three months and everything feels harder than it should, this is the one you need, and a single high-carbohydrate day will not substitute for it.
Neither is a cheat day, which is a different thing again and mostly a psychological framing rather than a physiological tool.
The order of operations
If your cut is going badly, work through it in this order rather than adding more restriction.
First, check the pace — more than about one percent of bodyweight a week is where training reliably deteriorates. Second, check protein is actually at target; it is the intake most likely to slip when total food is low. Third, check whether volume has come down at all; most people cut calories and keep training identically, which is asking recovery to do two hard jobs at once. Fourth, take a diet break.
Only after all four would it make sense to conclude that something is genuinely wrong — and at that point the answer is a conversation with a professional rather than another adjustment to the numbers.
