This is the ledger the guides are written from. Each entry says what we claim, what that claim does not extend to, and which source it rests on. It is here so a statement can be checked one claim at a time rather than by reading an article and hoping.
Meals built soft and small-particle, which is the dietary lever a recipe can genuinely control and one current guidance supports. Portion size is yours to set: these are written at an ordinary serving and divide in two if you are eating smaller and more often. Diagnosing, curing or treating gastroparesis is not something food does. If eating is not going in, if you are dehydrated or losing weight without meaning to, that needs a clinician rather than a different recipe.
Statements this site makes, each with the source behind it.
Gastroparesis is identified with tests that measure how fast the stomach empties rather than from symptoms alone, and the standard gastric emptying scan takes about four hours.
How we use it: Symptoms alone do not establish gastroparesis, and this site must not diagnose it or invite a reader to self-label from how food feels. Which test is appropriate is a clinical decision.
“Gastric emptying scan, also called gastric emptying scintigraphy. For this test, you eat a bland meal—such as eggs or an egg substitute—that contains a small amount of radioactive material. A camera outside your body scans your abdomen to show where the radioactive material is located. By tracking the radioactive material, a health care professional can measure how fast your stomach empties after the meal. The scan usually takes about 4 hours.. Gastric emptying breath test. For this test, you eat a meal that contains a substance that is absorbed in your intestines and eventually passed into your breath. After you eat the meal, a health care professional collects samples of your breath ove.”
The four-hour figure, from the patient guidance describing the scan.
“Doctors use lab tests, upper gastrointestinal (GI) endoscopy, imaging tests, and tests to measure how fast your stomach is emptying its contents to diagnose gastroparesis.”
Replaces an earlier claim that the 2025 AGA guideline requires a four-hour test. That guideline is paywalled from here and its research ledger entry records only its dietary statement, so the attribution was dropped rather than left unverified.

Dietary modification with low-fat, small-particle meals is part of initial gastroparesis management in the 2025 AGA guideline.
How we use it: This is a general dietary strategy, not a universal menu, cure or substitute for assessment of nutrition status, diabetes, medicines or severe symptoms.
The guideline’s general implementation considerations state that panel content experts use dietary interventions with small-particle and low-fat, low-residue diets before pharmacological intervention or as a concomitant intervention.
Carried deliberately: this is an implementation consideration, so the claim must not be presented as a separately graded recommendation.
“Six adult studies (185 subjects) met the inclusion criteria, whereas no pediatric study did. The data presented in this review suggest specific dietary interventions could potentially improve Gp symptoms and gastric emptying in adult patients, particularly low-fat and small-particle diets.”

NIDDK guidance describes five or six small nutritious meals, lower-fat and lower-fibre choices, and soft well-cooked foods as common dietary strategies.
How we use it: These are general patient-care strategies. Individual tolerance and nutrition adequacy matter, and more restriction is not automatically better.
“If you have gastroparesis, your doctor may recommend that you eat or drink; foods and beverages that are low in fat; foods and beverages that are low in fiber; five or six small, nutritious meals a day instead of two or three large meals; soft, well-cooked foods. If you are unable to eat solid foods, your doctor may recommend that you drink; liquid nutrition meals; solid foods puréed in a blender. Your doctor may also recommend that you drink plenty of water or liquids that contain glucose and electrolytes, such as; low-fat broths and clear soups; low-fiber fruit and vegetable juices; sports drinks; oral rehydration solutions.”

Repeated vomiting and poor intake can lead to dehydration, malnutrition, low calorie intake and unintentional weight loss in gastroparesis.
How we use it: Red-flag and nutrition-risk content should direct readers to medical care rather than offering a cookbook workaround for severe or worsening intake problems.
“You should seek a doctor’s help if you have any signs or symptoms of dehydration, which may include; extreme thirst and dry mouth; urinating less than usual; feeling tired; dark-colored urine; decreased skin turgor, meaning that when your skin is pinched and released, the skin does not flatten back to normal right away; sunken eyes or cheeks; light-headedness or fainting.”

What we say with conditions attached
Statements that hold only within stated limits. The limits are the point.
A randomized trial found that a small-particle diet improved key upper gastrointestinal symptoms in people with diabetic gastroparesis.
How we use it: The trial population had diabetes. Do not generalize its effect size to every cause of gastroparesis or claim that particle-size modification corrects gastric emptying.
Fifty-six insulin-treated participants with diabetes and gastroparesis were followed for 20 weeks in a dietitian-directed intervention. The small-particle group had greater reductions in several upper-gastrointestinal symptoms including nausea and vomiting, postprandial fullness and bloating.

A systematic review found limited evidence supporting strategies including low-fat and small-particle diets for gastroparesis.
How we use it: The evidence base is small and heterogeneous; do not present one restrictive diet as proven best for every person.
“Six adult studies (185 subjects) met the inclusion criteria, whereas no pediatric study did. The data presented in this review suggest specific dietary interventions could potentially improve Gp symptoms and gastric emptying in adult patients, particularly low-fat and small-particle diets.”

When solid food is poorly tolerated, clinical guidance may use liquid nutrition or puréed foods to help maintain intake.
How we use it: Do not prescribe an all-liquid diet or imply that blending is required for everyone. Persistent inability to meet nutrition or hydration needs needs clinical and dietetic review.
“If you are unable to eat solid foods, your doctor may recommend that you drink; liquid nutrition meals; solid foods puréed in a blender.”

Higher-fat solid meals can provoke more gastroparesis symptoms than lower-fat or liquid meals in a small randomized meal study.
How we use it: The study was small and tested acute meal responses. It does not justify eliminating fat or assuming all liquid high-fat foods will be tolerated.
A high-fat solid meal produced the greatest symptom increase and a low-fat liquid meal the least; liquid meals were better tolerated than solids for nausea.
A small meal study; supports fat burden and physical form, not a menu.
“Six adult studies (185 subjects) met the inclusion criteria, whereas no pediatric study did. The data presented in this review suggest specific dietary interventions could potentially improve Gp symptoms and gastric emptying in adult patients, particularly low-fat and small-particle diets.”

Diabetes management can become more complex with gastroparesis because glucose and food absorption may become difficult to match.
How we use it: Do not provide insulin timing or dose changes. Glucose-lowering treatment belongs with the person’s clinical team.
“You should seek a doctor’s help right away if you have any of the following signs or symptoms:; severe pain or cramping in your abdomen; blood glucose levels that are too high or too low; red blood in your vomit, or vomit that looks like coffee grounds; sudden, sharp stomach pain that doesn’t go away; vomiting for more than an hour; feeling extremely weak or fainting; difficulty breathing; fever.”

Some medicines can delay gastric emptying or worsen gastroparesis-like symptoms.
How we use it: Do not tell readers to stop, start or change prescribed medicines. Medication review belongs with the prescriber.
“Certain medicines may delay gastric emptying or affect motility, resulting in symptoms that are similar to those of gastroparesis. If you have been diagnosed with gastroparesis, these medicines may make your symptoms worse.”

A registry of 305 people with gastroparesis found average intake at 58% of energy needs and 2% following the recommended diet. What that does to how the usual advice should be read.
Low fat and low fibre travel together in every gastroparesis handout, as though they had the same evidence standing behind them. They do not, and knowing which is which changes how tightly you should hold each one.
Liquid and blended meals get treated as the bottom of a ladder people feel ashamed to be standing on. The clinical logic runs the other way, because the realistic alternative to a blended meal is very often no meal at all.
One randomised trial sits underneath the advice, and what it randomised was not a menu. It was twenty weeks of teaching people to change what their food does after they have swallowed it.
The advice is one line long and its consequences fill a week. Splitting a day of nutrition across six sittings changes shopping, cooking, work and appetite, and the word doing the heavy lifting in it is nutritious.
Small meals, low fat, low fibre, small particles: the gastroparesis diet is four rules that get handed over as one. Only one has a randomised trial behind it, two are guideline implementation notes, and all four take food away from people who, in the largest registry study, were already eating far too little. Here is the whole picture on one page.
In diabetic gastroparesis the diet has two jobs that pull against each other: the stomach needs small, soft, low-fat meals, and the blood glucose needs carbohydrate that arrives when the insulin does. The only randomised trial of the small-particle diet was run in exactly this group. What it found, and how to eat so both jobs get done.
