Shopping, cooking and storing food when there is only one person eating.
Last revised
Key takeaways
- Freezer life for most cooked dishes: up to 3 months
- Fridge life, cooked leftovers: 3 days
- Most useful single change: Cook a normal quantity and freeze in single portions.
- Commonest mistake: Buying fresh produce in family quantities.
- See a doctor if any of the signs under "When to get help" below apply to you.
Why it matters
Portioning, waste and motivation all work against single households, and the usual advice assumes a family.
The numbers, in one place
| Measure | Figure |
|---|---|
| Freezer life for most cooked dishes | up to 3 months |
| Fridge life, cooked leftovers | 3 days |
| Frozen and tinned | nutritionally comparable and waste far less |
| Cool cooked food within | about 1 hour |
| Eggs, tinned fish and pulses | single-portion protein with long shelf lives |
What helps
- Cook a normal quantity and freeze in single portions
- Buy frozen vegetables, which portion exactly as needed
- Keep long-life protein sources for days you cannot face cooking
- Label and date everything you freeze
What to avoid
- Buying fresh produce in family quantities
- Skipping meals because cooking for one feels not worth it
- Reheating a portion more than once

When to get help
See a GP for unintentional weight loss or a persistent loss of appetite, which is common in older adults living alone and should be assessed rather than accepted. Ask about social prescribing if isolation is affecting your eating.

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.
