High fat foods can slow down stomach emptying (e.g. fried foods, pastries, baked foods, fatty meats). Fats in liquid form (e.g. full cream milk, nutritional supplements, or yoghurt) are usually better tolerated.
Fat naturally slows stomach emptying. Consuming foods labeled “low fat,” “nonfat,” or “fat-free” may help with symptoms. Avoid all high fat, fried or greasy foods.
The rate of gastric emptying is decreased by the temporary occurrence of gastric dysrhythmias, modulation of the amplitude and the propagation distances of antral contractions, enhanced contractions of the pylorus, and reduced antropyloroduodenal coordination.
Leptin interacts with the vagus nerve and cholecystokinin to delay gastric emptying.
A number of factors have been identified that influence the rate of gastric emptying (Brouns et al., 1987), including: CHO concentration (osmolality), CHO source (osmolality), exercise intensity, meal volume, meal temperature, fat and protein in the ingestate, particle size, and dietary fiber.
Meat, milk, hard cheese and refined carbohydrates, such as white sugar, white flour and instant oatmeal pass slowly through the digestive tract and can slow peristalsis.
An anti-inflammatory diet, regular exercise, good quality sleep, and probiotics are all strategies to put in place before trying antimicrobials or antibiotics to get rid of bad bacteria.
Oats. Oats contain a unique type of fibre that nourishes and restores healthy gut bacteria. This makes oats a great food to eat every day and they are especially suited to breakfast – porridges, muesli or a smoothie with oats.
Prebiotic foods (whole grains, bananas, greens, onions, garlic, soybeans, and artichokes) act as food for healthy gut bacteria. Probiotic foods like yogurt are full of good bacteria already.
Increasing the number of daily meals and decreasing the size of each one can help alleviate bloating and possibly allow the stomach to empty more quickly. Some medical professionals recommend that people eat three small meals and two snacks throughout the day.
Pro-inflammatory foods include the following: simple and refined sugars (high glycemic carbohydrates), unhealthy fats, ultra-processed foods, charred foods, excessive alcohol, conventional corn-fed meat and dairy, and processed food chemicals and artificial sweeteners.
Plain water empties rapidly from the stomach, while increasing the energy content of ingested solutions slows the rate of gastric emptying.
Rapid gastric emptying is a result of stomach surgery such as surgery for gastric or abdominal ulcers, anti reflux surgery or gastric bypass. The condition is also seen in people with Zollinger-Ellison syndrome, a rare disorder involving extreme peptic ulcer disease and gastrin-secreting tumors in the pancreas.
Eat less fiber and fat. These can slow stomach emptying. You may feel OK if you stay under 2-3 grams of fiber with each meal. You might need to try to keep your fat between 30 and 50 grams or less per day.
Loss of strength or organization of contractions of the peristaltic pump leads to poor mixing and slow gastric emptying, while the increased strength of peristaltic contractions leads to the fast gastric emptying of the digestible solids20 (Table 1).

We conclude that meal volume has a major effect on gastric emptying; in contrast posture has only a minor impact on intragastric meal distribution, which is observed only after a large meal, and no effect on gastric emptying.
Conclusion: Extended fasting durations decrease the rate of gastric emptying and colonic motility.
