Why sleep matters
Sleep is often the forgotten part of weight management. Regularly sleeping too little is linked with changes in appetite, more snacking and lower energy for activity.
How poor sleep can affect weight
- Tiredness can make high-energy foods more appealing.
- Late nights add more time for eating.
- Low energy makes activity harder to keep up.
Practical steps
- Keep regular sleep and wake times, including at weekends.
- Build a wind-down routine and keep the bedroom dark, quiet and cool.
- Limit caffeine later in the day and avoid large meals just before bed.
- Get daylight and activity earlier in the day.
When to get help
If you often struggle to sleep, snore heavily or feel very sleepy in the day, speak to your GP — conditions such as sleep apnoea are more common with excess weight and are treatable.
