The effects of volume and posture on gastric emptying and intragastric distribution of a solid meal and appetite were evaluated. Eight normal volunteers were studied on four occasions, on each of which a meal comprising ground beef mixed with tomato sauce of either 650 g ("large") or 217 g ("small") was eaten. Two studies were performed while the subject was lying in the left lateral decubitus position, and two studies were performed while the subject was sitting so that in each subject data…

Effects of posture on gastric emptying and satiety ratings after a nutritive liquid and solid meal.
TLDR
The results suggest that posture did not affect the intragastric distribution of the sandwich but affected propulsion of the meal into the intestine and that postprandial satiety was enhanced by the cumulative effect over time of a 20-min "head start" in stimulation of intestinal receptors by emptying of the soup.
The effect of body position on postprandial perceptions, gastric emptying, and intragastric meal distribution: An ultrasonographic study in reclining healthy subjects
TLDR
The results suggest that lying on the left side after a meal may be a measure to reduce postprandial dyspepsia and gastric emptying is faster, and antral area is wider in the RLR position compared to the LLR position.
Comparison of gastric emptying of a solid and a liquid nutritional rehabilitation food
TLDR
Attempts to replace liquid nutritional rehabilitation foods by a solid food in malnourished patients should take into account a possible slower gastric emptying, according to a significant interaction term between the type of food and time indicating a delayed elimination of 13CO2 for the solid food.
Effect of postprandial posture on digestion and absorption of dietary carbohydrate.
TLDR
It is suggested that the postprandial supine position is preferable to the sitting position for the digestion and absorption of dietary carbohydrate and the hypothesis that there was a marked effect of postpr andial body posture on the function of the digestive system is supported.
Gastric and intestinal satiation in obese and normal weight healthy people
Effect of Meal Volume on Hunger and Satiety in Obese Subjects
TLDR
Food volume has only limited influence on satiety state directly after meal consumption but not glucose and insulin plasma concentrations, which is significant more satiating efficiency of bigger than smaller volume.
Effects of meal size and proximal-distal segmentation on gastric activity.
TLDR
Intragastric distribution of the meal between the proximal and distal compartments was strongly influenced by the way in which the stomach was divided, showing greater proximal retention after the 180 mL.
Does body posture affect the parameters of a cutaneous electrogastrogram?
TLDR
By carefully observing procedural guidelines, good quality electrogastrograms can be obtained with a sitting subject, enabling the provision of comparable parameters to those achieved from standard examination in a recumbent position.
Slower eating rate is independent to gastric emptying in obese minipigs
Effects of the amount of rice in meals on postprandial blood pressure in older people with postprandial hypotension: a within-subjects design.
TLDR
Reducing the amount of rice intake per meal prevents postprandial blood pressure decreases in the older people, and small and frequent meals with decreased carbohydrate content are recommended to prevent postPRandial hypotension and its complications in the elderly people.

Effect of the energy density of a solid-liquid meal on gastric emptying and satiety.
TLDR
It is shown that satiety depends on gastric emptying of energy and is not affected by the energy density of food intake.
Effect of meal volume on gastric emptying
TLDR
Meal volume accelerated gastric emptying provided the process is not rate‐limited by trituration, and steak emptying was independent of meal volume while sphere empties was affected by the number of spheres in the stomach and that liquid emptied was dependent on the meal volume.
Relationships between gastric emptying of solid and caloric liquid meals and alcohol absorption.
TLDR
It is concluded that gastric emptying of liquid may be influenced by solid food and that the rate and pattern of solid emptying may be modified by the presence of liquid.
Effects of posture on gastric emptying of nonnutrient liquids and antropyloroduodenal motility.
TLDR
It is concluded that the effects of gravity on gastric emptying of nonnutrient liquids are likely to reflect changes in both antropyloric motility and intragastric distribution.
Effect of meal volume and energy density on the gastric emptying of carbohydrates.
Gastrointestinal correlates of the development of hunger in man
Effects of small intestinal nutrient infusion on appetite and pyloric motility are modified by age.
TLDR
The effect of small intestinal lipid infusion on hunger is attenuated, and the stimulation of phasic pyloric pressure waves increased in healthy older persons compared with healthy young males, which does not appear to be responsible for the physiological anorexia of aging.
Inhibition of gastric emptying by glucose depends on length of intestine exposed to nutrient.
TLDR
It is concluded that glucose sensors are present in both the proximal and the distal gut and the inhibition was related to the length of the small intestine exposed to glucose.
Gastric volume rather than nutrient content inhibits food intake.
TLDR
Although both limited gastric distension with the pylorus occluded and intestinal nutrient stimulation with the cuff open effectively reduced intake, cuff-closed gastric loads of mixed macronutrients or carbohydrate solutions of 2-8 kcal, pH from 5.8 to 6.7, and osmolarities between 117 and 2,294 mosM/kg produced only the distension-based suppression generated by the same volume of saline.
