Prebiotics and Weight Management
Non-digestible fibres that feed beneficial gut bacteria and may support weight management through the gut-brain axis.
Plain English
Patient-Friendly Explanation
Prebiotics are special types of dietary fibre that feed the good bacteria living in your gut. Foods rich in prebiotics — such as garlic, onions, bananas, asparagus, and oats — help these beneficial bacteria thrive, which in turn may support healthier metabolism and easier weight management.
Medical
Clinical Definition
Prebiotics are non-digestible food ingredients, primarily oligosaccharides and inulin-type fructans, that selectively stimulate the growth or activity of beneficial gut microorganisms, particularly Bifidobacterium and Lactobacillus species. Through fermentation to short-chain fatty acids (SCFAs) such as butyrate, propionate, and acetate, prebiotics influence GLP-1 secretion, improve insulin sensitivity, and modulate appetite-regulating pathways via the gut-brain axis.
Key Insight
Why It Matters
Incorporating prebiotic-rich foods into your diet is a natural, food-based approach to improving gut health, which research increasingly links to successful long-term weight management. Dr Joseph Wang and the Accord Medical team include gut health assessments as part of a comprehensive weight loss strategy.
