Gut microbiota-derived short-chain fatty acids (SCFAs), specifically propionate, improve insulin sensitivity and glucose homeostasis by stimulating intestinal gluconeogenesis via the GPR43 receptor and a gut-brain neural circuit.
Consuming prebiotic fibers that generate propionate (a type of SCFA) can help improve your body's ability to manage blood sugar. This happens through a communication pathway between your gut and brain. Focus on foods rich in resistant starches and inulin to support this natural glucose-regulating mechanism.
Specifically, they found that propionate acts on GPR43 in the periportal afferent neural system to induce intestinal gluconeogenesis via a gut-brain neural circuit and, eventually, has beneficial effects on host physiology [13].

More from this paper
- Dietary prebiotics (non-digestible carbohydrates) improve leptin sensitivity and reduce food intake in diet-induced obesity by modulating gut microbiota to increase short-chain fatty acid (SCFA) production, which activates GPR41/43 receptors and reduces low-grade inflammation.Moderate
- Gut microbiota composition influences the secretion of anorexigenic gut peptides (GLP-1 and PYY) and reduces orexigenic ghrelin, thereby reducing food intake and body weight, mediated by microbial fermentation of non-digestible carbohydrates.Moderate

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
