Stomachs: does the size matter? Aspects of intestinal satiety, gastric satiety, hunger and gluttony
Many surgeons and most laypeople think that there is a strict correlation between the size of the stomach and the size of the meals. The term ‘‘stomach reduction’’ became a synonym for weight loss surgeries, as if by reducing the stomach, all meals would automatically be small. However, there is no strict correlation between the size of this organ and the size of meals. Some morbidly obese pati...
متن کاملChemical specificities and intestinal distributions of nutrient-driven satiety.
We measured intakes of sham- and naturally feeding rats during gut perfusions of nutrients. Our objectives were to determine 1) which nutrient products in gut lumen suppressed intakes; 2) how suppression by various nutrients is distributed along gut; and 3) whether time courses of suppression were similar among different nutrients. We found that satiating nutrients consisted of fatty acids only...
متن کاملLength of intestinal contact on nutrient-driven satiety.
Chemosensors throughout small bowel and colon inhibit food intakes when contacted by monomeric nutrients. We postulated that calorie-dependent inhibition of food intakes depended on additions of feedbacks from sensors in proximal and distal bowel contacted after high intakes of nutrients. Therefore, we determined how feedback from sensors in proximal gut interacted with feedback from simultaneo...
متن کاملAccumbal Cholinergic Interneurons Differentially Influence Motivation Related to Satiety Signaling
Satiety, rather than all or none, can instead be viewed as a cumulative decrease in the drive to eat that develops over the course of a meal. The nucleus accumbens (NAc) is known to play a critical role in this type of value reappraisal, but the underlying circuits that influence such processes are unclear. Although NAc cholinergic interneurons (CINs) comprise only a small proportion of NAc neu...
متن کاملApoA-IV: current and emerging roles in intestinal lipid metabolism, glucose homeostasis, and satiety.
Apolipoprotein A-IV (apoA-IV) is secreted by the small intestine on chylomicrons into intestinal lymph in response to fat absorption. Many physiological functions have been ascribed to apoA-IV, including a role in chylomicron assembly and lipid metabolism, a mediator of reverse-cholesterol transport, an acute satiety factor, a regulator of gastric function, and, finally, a modulator of blood gl...
