Prebiotic supplementation with non-digestible carbohydrates (e.g., oligofructose, inulin) improves glucose tolerance and insulin response by increasing GLP-1 secretion and SCFA production.
Incorporate prebiotic fibers like inulin or oligofructose into your diet. These are found in foods like chicory root, garlic, and onions, or taken as supplements. They feed gut bacteria that produce beneficial compounds (SCFAs) and stimulate hormones (GLP-1) that help lower blood sugar and reduce appetite.
GoodSupportsHIGH confidence
The addition of non-digestible carbohydrates, such as oligofructose, in the diet has been shown to improve glucose tolerance, insulin response, and to reduce food intake in mice and humans. These beneficial metabolic effects have been linked to higher plasma GLP-1 levels
Why this rating
Supported by multiple animal studies and some human trials, though human data is less extensive than animal data.

- Gut microbiota composition directly influences host glycemic control and insulin sensitivity through mechanisms including incretin secretion, short-chain fatty acid (SCFA) production, and bile acid metabolism.Good
- Antidiabetic drugs like metformin and liraglutide exert part of their beneficial effects by modifying gut microbiota composition, specifically by increasing the abundance of Akkermansia muciniphila.Good

- 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
