This page exists for two reasons. Keeping weight off is the harder half of the task and gets a fraction of the attention. And stability is the single thing that determines whether any decision about skin can sensibly be made.

What “stable” actually means
It does not mean an unchanging number. Weight fluctuates by one to two kilograms across a week in everybody, from fluid, food volume and hormonal cycling. That is noise, not change.
Stable means the trend is flat over months. A practical definition: your weight has stayed within about two to three kilograms of the same figure for at least six months, without active dieting to hold it there.
Six months of that gives a reasonable picture of your final shape. Twelve gives something close to final.
Plateaus are not regain
A plateau is weight loss stopping while you are still trying. It is the expected consequence of a smaller body needing less energy, and it happens to everyone.
Regain is weight going back up. Different thing, different response.
The common error is treating a plateau as failure and responding by cutting harder, which increases lean tissue loss and makes the eventual maintenance harder. A plateau is usually the point to stop losing and start practising maintenance, which is a separate skill.
Some regain is normal
Most people who lose a large amount of weight regain some of it. That is the expected pattern rather than a failure, and the meaningful question is whether it settles at a new, lower level or continues upward.
For the purposes of this site, it matters for one reason: a plan made about skin while weight is climbing is a plan made on the wrong body. That is not a judgement, it is arithmetic.
What maintenance actually requires
The uncomfortable finding from the research on people who maintain large losses long-term: it takes ongoing, active effort, more or less permanently. Regular weighing, continued resistance training, sustained protein intake, and a level of attention that does not switch off.
Where medication is part of the picture, whether to continue is a conversation for your prescriber. What is well established is that stopping is frequently followed by regain.
Why this page pairs with the assessment
Every timing question on this site reduces to whether the weight has settled. If you are unsure, the readiness assessment works through it — and a result of “not yet” is a useful answer, not a disappointing one.
More on keeping muscle, which is the part of maintenance that most affects how the final result looks.
