Fatigue, sleep and nutrition
Chronic fatigue first has medical causes to rule out. Once that has been done, meal distribution, caffeine and timing genuinely affect daytime energy and sleep quality.

Rule out medical causes with your doctor
Meal regularity, caffeine, adapted dinner
Structuring the day
Skipping meals then compensating in the evening degrades both daytime energy and sleep. A dinner that is too late, too heavy or too alcoholic also fragments sleep, even when falling asleep feels easy.
- Even distribution of intake through the day
- Caffeine: last intake in the early afternoon
- A lighter, early-enough dinner
- Specific organisation for shift or night work
Situations commonly supported
Mid-afternoon energy dips, late-evening hunger, a skipped breakfast followed by a very large lunch, shifted hours or shift work: these patterns come up often in consultation.
- Spreading energy and protein across the day
- Caffeine, alcohol and the evening meal
- Meal organisation with shifted schedules
When medical advice is needed
Persistent fatigue can have a medical cause: anaemia, thyroid disorder, sleep apnoea, depression, a medication effect. These must be investigated by your doctor; dietetic work then contributes, alongside, on meal rhythm and intake coverage.
What belongs to your physician
Diagnosis, tests and medical treatment remain your doctor's responsibility. Dietetic support adapts to them and, with your agreement, a report is sent to your doctor.
Circadian rhythm and meals

Morning: metabolic wake-up
