Weight Maintenance: A Beginner-Friendly Start
Weight Maintenance: the few things that matter most, and the mistakes that catch people out early.
Keeping weight off after losing it, which has its own evidence base and its own skills.
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.
Why bother
Most attempts succeed at losing and fail at keeping, and maintenance behaviour looks different from losing behaviour.
Start here
Start with two. Add the rest once those have stopped taking effort.
- Write the maintenance plan before reaching the target
- Keep weighing at a regular interval as a feedback loop
Then add these
Once the basics are in place, add these.
- Keep activity at the higher level rather than returning to baseline
- Decide in advance what you will do after a bad week
The numbers, in one place
| 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 |
Common early mistakes
- 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

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.
