If your stomach is running on GLP-1 diarrhea, eat small, bland, low-fat meals built on bananas, white rice, applesauce, toast, broth and lean protein, and pause fried food, sugar alcohols, caffeine and raw roughage until things settle. By the end of this page you will have a two-column swap list you can paste into your phone and a rule for when it is a food problem and when it is a call-your-prescriber problem.
Keep eating, but change what is on the plate
Loose stools are not a reason to stop eating, and with a shrunken appetite you cannot afford to skip meals. The goal is the same plate, rebuilt. Bland, low-fat, binding foods such as bananas, rice, applesauce, toast and broth are usually easier to tolerate until symptoms settle. Small, frequent meals of easy-to-digest food beat three big ones, which suits you anyway when four bites is your limit.
So the first rule is simple. When stools are loose, shrink the portion, lower the fat, and eat more often.

Category
Reach for
Pause for now
Fat
Skinless chicken or turkey, white fish, egg whites, nonfat plain yogurt
Fried food, fast food, fatty cuts, processed meats, cream sauces
Fiber
Oats, bananas, applesauce, beans, apples (soluble)
Raw vegetables, vegetable skins and stalks, whole-wheat bread (insoluble)
Drinks
Water, broth
Caffeine, alcohol, sugary juice, anything sweetened with sorbitol or xylitol
Seasoning
Salt, mild herbs
Spicy dishes
The “pause” column is not a ban list. It is what GoodRx and Ro both flag: greasy or fried foods, spicy dishes, full-fat dairy, caffeine, alcohol, sugary juices and sugar alcohols. Put the foods back one at a time once your stools firm up, so you know which one bit you.
Fiber is where people get this wrong
If you read the constipation page last week and loaded up on chia and bran, stop. Fiber comes in two kinds, and they pull in opposite directions during diarrhea.
Insoluble fiber hurts. Vegetable skins, stalks, whole-wheat bread and most raw vegetables can speed intestinal movement and make things worse.
Cruciferous vegetables add gas. Broccoli, cauliflower and cabbage go on the pause list, and the gas and vegetables page has swaps.
The rule: when stools are loose, lean on soluble fiber and pause the insoluble kind. When they firm up, bring the roughage back slowly.
Watch the sugar-free stuff, especially protein bars
This one catches people who are trying hard to hit protein. Sugar alcohols such as sorbitol and xylitol are on the list of things to pause, and they show up in “sugar-free” bars, shakes, gum and candy. Read the ingredient list before you rely on a bar for protein this week. If you see a word ending in “-ol”, set it aside.
Keep protein up with the lowest-fat options
Protein still matters on a bland plate. Pick the lean end: skinless poultry, white fish, egg whites, nonfat plain yogurt, tofu. Fatty cuts, processed meats and cream sauces are on the pause list, so the usual shortcuts (sausage, cheese sauce, fried chicken) are out for now.
For gram numbers per cup, use the protein density chart and sort by what you can tolerate today. A small bowl of something lean and soft, eaten every couple of hours, does more than one big plate you cannot finish.
A sample day on the bland plate
Example: say your stools are loose and you can manage about five small stops across the day. Here is how the swap list turns into food.
Morning: a small bowl of oatmeal made with water, half a banana.
Mid-morning: nonfat plain yogurt with a spoon of applesauce.
Lunch: white rice with skinless chicken, salt and a mild herb, plus broth.
Afternoon: two scrambled egg whites on a slice of toast.
Dinner: baked white fish with rice. No cream sauce, no fried coating.
Nothing on that list is fancy, and that is the point. Water or broth between stops, not with a big gulp at the table.
How common is this? Here is what the labels say
You are not unusual. The prescribing information for each product lists diarrhea among its most common reactions. These are trial rates from two different labels, so they are not a head-to-head comparison and not a forecast for you.
Do the subtraction yourself to read a label honestly. Wegovy: 30 minus 16 is 14 points above placebo. Zepbound 15 mg: 23 minus 8 is 15 points. The placebo column matters, because some people report loose stools with no drug at all.
One more number from the Wegovy label: diarrhea led to stopping treatment in 0.7% of Wegovy patients, against 0.1% on placebo. It is common, and it rarely ended treatment in the trials. That is a label fact, not a promise about your case. This site is independent of Eli Lilly and Novo Nordisk, and the product names are here only to say which label a number came from.
Fluids come first when you are losing them
Put water ahead of the food list. Diarrhea takes fluid with it, and the Zepbound label warns that dehydration from nausea, vomiting and diarrhea can lead to acute kidney injury. It also says kidney function should be monitored in people with reactions that could cause volume loss. If you want a timing rule for fluids around meals when your stomach is small, the 30-minute water rule covers it.

Do this in the next ten minutes
Copy the swap table into your phone notes.
Check your protein bars and shakes for sorbitol and xylitol.
Put out a banana, a pot of cooked white rice or a cup of applesauce, and a jar of broth so the easy option is the close one.
Set a timer for a small portion of something lean every two to three hours.
Write down the first food you add back when stools firm up, and the day you did it.

Common questions
What should I eat when GLP-1 gives me diarrhea?
Small, frequent, bland and low-fat meals: bananas, white rice, applesauce, toast, broth, plus lean protein such as skinless poultry, white fish and egg whites. Add soluble fiber like oats and apples, and sip fluids through the day.
Is fiber good or bad for GLP-1 diarrhea?
It depends on the kind. Soluble fiber from oats, beans and apples can absorb excess water in the intestines. Insoluble fiber from raw vegetables, skins and whole-wheat bread can speed movement through the gut, so pause it until stools firm up.
Can I still hit my protein with diarrhea?
Yes, by choosing the lowest-fat protein you tolerate: skinless chicken or turkey, white fish, egg whites, nonfat plain yogurt or tofu. Eat small portions every few hours instead of one big plate.
Do sugar-free products make GLP-1 diarrhea worse?
Sugar alcohols such as sorbitol and xylitol are on the lists of things to pause. They hide in sugar-free bars, shakes, gum and candy, so check ingredient lists on your protein products.
How common is diarrhea on GLP-1 medications?
The Wegovy label reports diarrhea in 30% of people on 2.4 mg versus 16% on placebo. The Zepbound label reports 19% to 23% across its doses versus 8% on placebo. These are separate trials, not a head-to-head comparison.
When should I call my prescriber about diarrhea?
Call if diarrhea comes with vomiting, if you cannot keep fluids down, or if it keeps going or is severe. The Zepbound label warns that dehydration from diarrhea can lead to acute kidney injury.
Before you go
Severe abdominal pain that goes through to your back, vomiting you
cannot stop, or an inability to keep fluids down are not food problems.
