![]() So the first signal that water needs are being met is mediated by receptors in the throat Water is absorbed much more quickly than food, but too much water can also be harmful. An increased understanding of these factors and the mechanisms whereby they exert their effects on satiety may offer a food-based So the first signal to indicate satiety is fullness of the stomach, as indicated by the stretch receptors native to the organ. The interplay of gut hormones affects the brain directly, as most gut hormones cross the blood-brain barrier and bind to their respective receptors in the central nervous system This was quite unexpected, because the dogma in the field for decades has been that stomach stretch receptors sense the volume of food being eaten and the intestinal hormone receptors sense its energy content, said postdoctoral researcher Ling Bai, PhD, who is first author of the team's published paper in Cell, which is titled, Genetic identification of vagal sensory neurons that control feeding Satiety, which is the inhibition of eating following the end of a meal, is influenced by a number of food characteristics, including compositional and structural factors. ![]() The satiety-hunger balance is kept in check by many anorexigenic gut hormones among which is the deacylated form of ghrelin-desacyl ghrelin. When small amounts of food are consumed, the stretching of the stomach is minimal however, as the volume of food increases, the stretch receptors are stimulated The actual stretching of the stomach after consuming a meal sends a message to the brain, which then tells the body it's full. XTREME ENDORPHIN WRESTLING FULL(C) Time-resolved responses following alternating perfusions of glucose (1 M in saline, green, 240 s) and sodium chloride (500 mM in saline, pink, 240 s) 14 The human stomach holds about 3‐4 cups of volume There are stretch‐receptors that tell the brain we are satisfied or full when the stomach is stretched, so for long‐term weight loss or satiety we want to aim for 3‐4 cups of volume per intake Ideal balance would be 2‐3 cups of non‐starchy vegetables (10‐25 calories each), 2/3‐1 cup protein (40‐120 calories), 1/3‐1/2 cup carbohydrates from fruit/starch/liquid dairy (60‐120 calories) to yield balance with sustainable results Gastric Stretching. Intestinal stretch was achieved by inflation with isotonic saline (green bars 30 s, 200 μl, 400 μl, 600 μl, 800 μl, 1 mL). Most of the calories found in a typical North American diet are made up of animal products and processed foods, meaning that most people are severely nutrient and fiber deficient Satiety signals are generated in the gastrointestinal (GI) tract during meals and provide information about mechanical (e.g., stomach stretch, volume) and chemical properties of the food (as indicated by CCK release) Stomach stretch was achieved by inflation with nitrogen gas. In our stomachs, we have nutrient (or caloric) sensors and stretch receptors.
