What People Get Wrong About Weight Maintenance
Weight Maintenance: what people commonly get wrong, set against what published UK guidance says.
Most attempts succeed at losing and fail at keeping, and maintenance behaviour looks different from losing behaviour.
Key takeaways
- Most common outcome without a maintenance plan: regain
- Associated with success: regular self-weighing and consistent eating patterns
- Most useful single change: Write the maintenance plan before reaching the target.
- Commonest mistake: Treating the target as the end of the process.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
What the guidance actually says
These are the numbers the corrections below are measured against.
| Measure | Figure |
|---|---|
| Most common outcome without a maintenance plan | regain |
| Associated with success | regular self-weighing and consistent eating patterns |
| Activity in maintenance | typically higher than before the loss |
| Clinically meaningful retained loss | 5 per cent or more |
| Best predictor of long-term outcome | the response to a lapse |
Where people go wrong
All of these come up regularly. All of them run against the published position.
- Treating the target as the end of the process
- Returning to the exact eating pattern that preceded the loss
- Abandoning the plan after a single large meal
What to do instead
- Write the maintenance plan before reaching the target
- Keep weighing at a regular interval as a feedback loop
- Keep activity at the higher level rather than returning to baseline
- Decide in advance what you will do after a bad week
The part that is genuinely uncertain
Guidance changes, and it changes because evidence does. The figures above reflect current UK guidance from the bodies named at the foot of this page; where those bodies revise their position, theirs is the account to follow rather than this one.

When to speak to a doctor
Speak to a GP if weight is rising despite consistent effort, particularly with fatigue, cold intolerance or hair changes, which can indicate thyroid problems. Some medicines cause weight gain and are worth reviewing rather than working around.
Where this comes from
How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
