high fat diet and slow gut

The small intestine has two types of motility patterns: fasting pattern which has three phases and occur slow cyclical style and diet responsible for slow the upper gut and food residues, and do diet sodas affect self control pattern which has unpredictable style similar to phase Gtu and serves to transit the food at a rate fat gives enough time for proper digestion and absorption. Dig Dis Sci ; 34 The proximal small intestinal transit seems to be increased in obesity and this may be secondary to efficient nutrient absorption and subsequent lack of nutrient-induced satiety signals conveyed from the small intestine.

The presence of fat in the small intestine slows gastric emptying, stimulates the release of many gastrointestinal hormones, and suppresses appetite and energy intake as a result of the digestion of fats into free fatty acids; the effects of free fatty acids are, in turn, dependent on their chain length. Given these effects of fat, it is paradoxical that high dietary fat intakes have been linked to increased energy intake and body weight and are considered to play a significant role in the pathogenesis of obesity. However, increasing evidence indicates that a chronic increase in dietary fat is associated with an attenuation of the feedback signals arising from the small intestine induced by fat, with a consequent relative acceleration of gastric emptying, modulation of gastrointestinal hormone secretion, and attenuation of the suppression of energy intake. This review addresses the gastrointestinal factors involved in the regulation of appetite and energy intake, with a particular focus on 1 the gastrointestinal mechanisms triggered by small intestinal fat that modulate energy intake, 2 the potential role of a high dietary fat intake in the development of obesity, and 3 implications for the prevention and management of obesity. Obesity can, in the broadest sense, be considered to be the result of an energy intake that exceeds energy expenditure. Signals arising from the gastrointestinal tract play a fundamental role in the regulation of appetite and energy intake, and evidence indicates that the gastrointestinal and hormonal mechanisms involved in the suppression of appetite and energy intake are compromised in obesity 1, 2. Hence, obesity may, at least in part, reflect a decreased sensitivity to the gastrointestinal effects of nutrients, particularly in the face of excessive calorie intake. Studies in animals and, to a much more limited extent in humans, indicate that consumption of a high-fat diet has the capacity to modulate the gastrointestinal responses to ingested fat and, thereby, leads to impairments in appetite regulation that favor the development of obesity. This review summarizes current knowledge about the gastrointestinal regulation of appetite and energy intake, with a particular focus on 1 the mechanisms triggered by fat in the gut that modulate energy intake, 2 the potential role of a high dietary fat intake in the pathogenesis of obesity, and 3 implications for the pathophysiology and prevention and management of obesity. Although an increased dietary fat intake apparently contributes to overconsumption 11, 12, it is pertinent to recognize that fat has effects in the gastrointestinal tract that favor the suppression of appetite and energy intake.

Furthermore, there is evidence that obese subjects have an increased preference for the consumption of fatty foods 86 and that fat proportion of dietary fat is high in obese, than in lean, individuals Physiol Behav slow 77 : 85 — Peptides ; 19 : — Gastroenterology ; : — 4. The hypertrophy of the high mucosa, and increased capacity for fat digestion, would and be expected to enhance the absorption of fat from the proximal small intestine and result in a decreased length of small intestinal exposure, which could, potentially, influence gut gastrointestinal diet and energy intake.
