Stopping treatment without losing the ground

What happens if you just stop

Two trials answer this directly, and they answer it in the same direction.

And it is not only the weight. Waist, blood pressure, non-HDL cholesterol and fasting insulin all moved back towards where they started, roughly in proportion to how much weight came back. The metabolic benefit is rented, not bought.

Then why does anyone stop?

Because they are real reasons. Cost, most commonly and by a long way. A planned pregnancy, which requires stopping about two months beforehand. Side effects that did not settle. Reaching a weight where the risk that justified the treatment has gone. Or simply having decided that indefinite treatment is not what they want, which is a legitimate choice for a patient to make.

Real world data are worth knowing here: somewhere between a third and a half of people are no longer on treatment at one year, and the dominant reasons are cost and supply rather than side effects. If you stop, you will be in ordinary company.

A structured stop

There is no trial telling us the best way to come off these treatments. Nobody has run it. What follows is a practical protocol built on what is known about how regain happens, and it is what we use. Treat it as considered clinical practice, not as proven fact.

1. Do not stop from the top dose Step down through the doses rather than dropping off a cliff, spending four to six weeks at each. Appetite comes back gradually instead of all at once, which is the difference between managing it and being ambushed by it.
2. Fix the protein and the training first, not afterwards Before the first reduction, the protein target should already be habitual and resistance training should already be happening twice a week. Muscle is what defends your resting energy expenditure, and you cannot build it during a taper. Anyone who has not done this work by the time they taper will regain faster.
3. Expect hunger to return, and know what it is It is not weakness and it is not a relapse. It is the same defended physiology that made you heavy in the first place, uncovered again. Naming it in advance is genuinely protective.
4. Weigh weekly, and set a line in advance Pick a number, usually two or three kilograms above where you finish, and decide now what happens if you cross it. A pre-agreed line turns a slow drift into a decision.
5. Come back at three months, whatever is happening Not only if it goes wrong. The three month visit after stopping is when it is still easy to intervene. The visit people actually make is at twelve months, by which time most of the ground is gone.
6. Restarting is not a failure If the weight and the risk come back, restarting is the correct clinical response, in the same way a blood pressure tablet is restarted. Coming back should not require an apology and will not receive a lecture.

What genuinely improves the odds

• Muscle kept during the losing phase. The single biggest modifiable factor.
• How long you were on treatment. Habits built over eighteen months hold better than habits built over four.
• Structured nutrition support alongside the medicine. People who had both lost more, adhered better, and were more likely to sustain the loss after stopping than people who had the medicine alone.
• Sleep and treated sleep apnoea. Untreated apnoea makes regain substantially more likely.
• A plan made before stopping rather than after.
