Nausea hits almost everyone starting GLP-1 medications. Up to half of patients feel it in the first few weeks.
The good news: certain foods can help. This guide covers what to eat when your stomach says no.
Why GLP-1s Cause Nausea
GLP-1 medications slow how fast your stomach empties. Food sits there longer. For some people, this feels like fullness. For others, it feels like nausea.
This effect is strongest when you:
- Start the medication
- Increase your dose
- Eat large meals
- Eat fatty or rich foods
The BRAT Diet (And Beyond)
Doctors often recommend the BRAT diet for nausea:
- Bananas
- Rice
- Applesauce
- Toast
These foods are bland, low-fat, and easy to digest. But you can't live on them forever. Let's expand the list.
Best Foods for GLP-1 Nausea
1. Saltine Crackers
The classic for a reason. Plain, dry, and easy.
- Eat 2-3 slowly when nausea hits. Best pick: Premium Saltines - classic, easy to tolerate
- Keep them by your bed for morning nausea
- Avoid flavored varieties (too strong)
2. Ginger
Proven to help with nausea.
- Ginger tea (warm, not hot)
- Ginger Chews - natural ginger, helps settle stomach
- Crystalized ginger (small pieces)
- Ginger ale (let it go flat first). Best pick: Canada Dry Ginger Ale - real ginger taste
3. Dry Toast
White bread, no butter. Keep it simple.
- Eat slowly
- Don't add jam or butter at first
- Works well for morning nausea
4. Bananas
Easy to digest, contain potassium.
- Ripe bananas are gentler
- Start with half if you're sensitive
- Good source of potassium you might be missing
5. Plain Applesauce
The "A" in BRAT.
- Choose unsweetened if possible. Best pick: Mott's Unsweetened Applesauce - no added sugar
- Start with small portions (1/4 cup)
- Avoid if you have sulfur burps (can make it worse)
6. White Rice
Bland and filling without being heavy.
- Cook until very soft
- No butter or oil at first
- Add a tiny bit of salt if needed
7. Clear Broth
Warm liquid that provides some sodium.
- Chicken or vegetable broth
- Sip slowly
- Avoid cream-based soups
8. Plain Oatmeal
Gentle fiber that stays down.
- Cook with water, not milk
- Skip sweeteners at first
- Start with small portions
9. Scrambled Eggs (If Tolerated)
Protein when you can handle it.
- Cook with minimal oil/butter
- Keep portions small (1-2 eggs)
- Skip cheese and spices at first
10. Electrolyte Drinks
Hydration matters.
- Sip slowly throughout the day
- Avoid sugary sports drinks. Best pick: Liquid I.V. Hydration Multiplier - electrolytes without excess sugar
- Clear liquids are easier than thick ones
Foods to Avoid During Nausea
When you're feeling sick, stay away from:
- Fatty foods — fried anything, cheese, cream sauces
- Spicy foods — hot sauce, peppers, curry
- Acidic foods — citrus, tomatoes, coffee
- Strong smells — garlic, onions, fish
- Large portions — eat small amounts frequently
- Carbonated drinks — can cause bloating
Timing Tips
Morning nausea:
- Keep crackers by your bed
- Eat 2-3 before getting up
- Wait 10 minutes before moving
After meals:
- Stay upright for 30 minutes
- Don't lie down right after eating
- Take a slow, short walk if possible
All day:
- Eat small amounts every 2-3 hours
- Don't let your stomach get completely empty
- Sip water constantly, don't chug
How Long Does This Last?
For most people:
- Week 1-2: Nausea peaks, especially after dose increases
- Week 3-4: Still present but improving
- Week 5-6: Much better for most people
- Month 2+: Mild or gone for many
If nausea is severe, persistent, or you can't keep fluids down, contact your doctor. You may need anti-nausea medication or a dose adjustment.
Sample Nausea-Safe Day
Morning:
- 2-3 saltine crackers before getting up
- Half a banana
- Sip water slowly
Mid-morning:
- Small bowl of plain oatmeal
- Ginger tea
Lunch:
- 1/2 cup white rice
- Small portion of scrambled eggs
- Clear broth
Afternoon:
- Applesauce (1/4 cup)
- Electrolyte drink
Dinner:
- Toast with a thin layer of peanut butter (if tolerated)
- Half a banana
This is survival mode. Once nausea improves, you can return to more normal eating.
When to Call Your Doctor
Seek medical help if you:
- Can't keep liquids down for 24+ hours
- Are losing weight too fast (more than 2 lbs/week consistently)
- Feel dizzy or faint
- Have severe stomach pain
- Notice blood in vomit or stool
