Many studies have identified that obesity is associated with a multitude of non-communicable diseases, such as cardiovascular disease, renal diseases, hypertension and type 2 diabetes Whitlock et al. Long-term body weight management could be improved by an increased intake of dietary fibre, as prospective cohort studies have shown that high-fibre diets are associated with lower weight gain Reynolds et al. In the United Kingdom, for instance, average daily fibre intake is A growing body of evidence suggests that the positive effects of dietary fibre on body weight gain may be due to the metabolites produced from microbial fermentation in the gut. Short-chain fatty acids SCFAs are the major metabolic end products of gut microbial fermentation of dietary fibre with acetate, propionate and butyrate, generated in an approximate molar ratio of Whilst acetate is synthesised in the liver following a prolonged fast or alcohol consumption, systemic SCFAs arise principally in mammals from the fermentation of dietary fibre in the gut Scheppach et al.

Medium chain triglycerides MCT have unique metabolic properties which may improve insulin sensitivity Si and beta cell function but data in humans are limited. We conducted a 6-week clinical trial of MCT oil supplementation. Dietary intake, PA data, body composition, and resting energy expenditure REE were obtained through dietary recall, international PA questionnaire, dual x-ray absorptiometry, and indirect calorimetry, respectively. Insulin-modified frequently sampled intravenous glucose tolerance tests were performed before and after MCT to measure changes in Si, acute insulin response AIR , disposition index DI , and glucose effectiveness Sg. MCT were well tolerated and weight remained stable mean change 0. Fasting REE, respiratory quotient, and body composition were stable during the intervention. There were no significant changes in mean fasting glucose, insulin, insulin resistance, fasting total ketones, Si, AIR, DI, Sg, leptin, fructosamine, and proinsulin.
The connection between the gut microbiota and the aetiology of obesity and cardiometabolic disorders is increasingly being recognized by clinicians. Our gut microbiota might affect the cardiometabolic phenotype by fermenting indigestible dietary components and thereby producing short-chain fatty acids SCFA. These SCFA are not only of importance in gut health and as signalling molecules, but might also enter the systemic circulation and directly affect metabolism or the function of peripheral tissues. In this Review, we discuss the effects of three SCFA acetate, propionate and butyrate on energy homeostasis and metabolism, as well as how these SCFA can beneficially modulate adipose tissue, skeletal muscle and liver tissue function. As a result, these SCFA contribute to improved glucose homeostasis and insulin sensitivity. Furthermore, we also summarize the increasing evidence for a potential role of SCFA as metabolic targets to prevent and counteract obesity and its associated disorders in glucose metabolism and insulin resistance.
SCFA might also indirectly affect muscle insulin sensitivity and glucose metabolism via increased systemic levels of gut-derived PYY and GLP
In recent years, the relationship between intestinal microbiota IM and the pathogenesis of type 2 diabetes mellitus T2DM has attracted much attention. The beneficial effects of IM on the metabolic phenotype of the host are often considered to be mediated by short-chain fatty acids SCFAs , mainly acetate, butyrate, and propionate, the small-molecule metabolites derived from microbial fermentation of indigestible carbohydrates. In this review, we summarize the effects of SCFAs on glucose homeostasis and energy homeostasis and the mechanism through which SCFAs regulate the function of metabolically active organs brain, liver, adipose tissue, skeletal muscle, and pancreas and discuss the potential role of modulation of SCFAs as a therapeutic method for T2DM.
Мидж покачала головой: - Настолько сложной, что она длится уже восемнадцать часов? - Она выдержала паузу. - Маловероятно. Помимо всего прочего, в списке очередности указано, что это посторонний файл.
Это явно не было составной частью плана. - У них там прямо-таки дискотека! - пролопотал Бринкерхофф. Фонтейн смотрел в окно, пытаясь понять, что происходит. За несколько лет работы ТРАНСТЕКСТА ничего подобного не случалось. Перегрелся, подумал .
Поравнявшись с задним бампером, он взял немного правее. Ему была видна задняя дверца: как это принято в Севилье, она оставалась открытой - экономичный способ кондиционирования.
