Hormonal

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.
