Should you eat before travel if you get motion sick?
Verdict: Untested
Do not travel on an empty stomach — the widespread advice to skip food before a journey appears to be backwards, though the trial evidence for what to eat instead is thin.
What it's claimed to do
Two pieces of folk wisdom in direct contradiction: skip food so there is nothing to bring up, versus line your stomach so you have something to settle it.
- YesTested for motion sickness and it held up.
- ProbablyReal trial support, but modest or from a single study.
- MixedTrials disagree — some found an effect, better-designed ones did not.
- Untestedthis remedyNo one has tested this for motion sickness. It may still be sensible.
- NoTested for motion sickness and it did not beat a placebo.
Levels describe the state of the published research on motion sickness specifically — not on nausea in general, and not how well something worked for any individual. “Untested” means no trial has looked; it is not the same as a remedy having been tested and failed.
What the research actually says
We have not found a controlled trial that randomized travelers to eat or fast before a journey, so nobody can claim this is settled. What exists is consistent guidance in the other direction: an empty stomach is not protective, and hunger itself tends to make nausea worse. Clinical and travel-medicine advice generally converges on a light meal rather than either extreme. There is a related and better-established thread in the ginger research, where the measurable effect was on gastric rhythm rather than on the inner ear — evidence that the stomach's state genuinely participates in motion sickness rather than merely receiving the consequences of it. That makes it plausible that arriving at a journey with a settled, moderately full stomach is better than arriving hungry, but plausible is the right word. The practical advice below is the conventional guidance, offered as sensible rather than as demonstrated.
The studies, in full
Am J Physiol Gastrointest Liver Physiol 284(3):G481-9 · PMID 12576305
Participants: 13 volunteers with a history of motion sickness
Showed that motion sickness involves measurable disruption of gastric rhythm, and that an intervention acting on the stomach reduced nausea — indirect support for the stomach's state mattering, though it tested ginger rather than food.
Read the source →Safety & what to watch for
- This is conventional guidance rather than a trial result. Anyone stating it with certainty is overreaching.
- Individual triggers vary a lot. If a particular food reliably precedes a bad journey for you, your own experience beats general advice.
- None of this applies to managing nausea in pregnancy, which has its own guidance — speak to a midwife or doctor.
- If nausea is stopping you from keeping food or fluids down for a prolonged period, that is a reason to seek medical advice rather than adjust your snacks.
If you want to try it
- Eat something light an hour or two before you set off rather than immediately before or not at all.
- Plain, dry, low-fat foods are the usual recommendation — bread, crackers, plain rice, banana. Heavy, greasy and strongly spiced meals are the usual things to avoid.
- Alcohol before or during a rough journey is worth avoiding; it affects the vestibular system directly and tends to make matters worse.
- Keep sipping water. Dehydration makes nausea harder to tolerate, and people who feel sick tend to stop drinking.

Frequently asked questions
Is it better to travel on an empty stomach?+
The general guidance says no. Hunger tends to worsen nausea, and an empty stomach does not prevent sickness — it mostly changes what happens if you are sick. A light meal beforehand is the conventional recommendation.
What should I eat before a ferry crossing?+
Something light, plain and low in fat, an hour or two before boarding, and enough water to stay hydrated. Avoid a heavy fried breakfast and alcohol. This is standard advice rather than a tested protocol.

When it isn't motion sickness. Severe or lasting dizziness, a spinning sensation at rest, hearing loss, ringing in one ear, double vision, a bad headache, chest pain, fainting, or vomiting you cannot stop are not motion sickness. Seek medical care rather than a travel remedy.
