Hunger hormones are chemical messengers that regulate appetite, signaling to the brain when to eat or stop eating. The main hunger hormone, ghrelin, stimulates appetite, while hormones like leptin, peptide YY (PYY), and GLP-1 help suppress hunger and promote feelings of fullness. These hormones work together to maintain energy balance and body weight.
Prebiotic foods are basically plant-based foods that feed the good bacteria in your gut, helping improve digestion and overall health.
Jerusalem artichokes, also known as sunchokes, are especially rich in inulin, a prebiotic fiber that supports gut health and keeps you feeling full longer.
Oats are another excellent option, as they contain beta-glucan, a type of soluble fiber that slows digestion and stabilizes blood sugar levels.
Plantains (Cooking bananas) are rich sources of starch that feeds gut bacteria and supports appetite control.
Onions, garlic, and leeks also provide prebiotic fibers that nourish beneficial gut microbes.
Mushrooms and asparagus contain both fiber and water, helping to increase satiety without adding many calories.
Inulin passes through the digestive tract undigested until it reaches the colon, where they are broken down-or fermented-by gut (pro-biotic) bacteria. This fermentation process produces short-chain fatty acids (SCFAs), such as acetate, propionate, and butyrate. These SCFAs trigger the release of appetite-regulating hormones like peptide YY (PYY) and glucagon-like peptide-1 (GLP-1), which help increase feelings of fullness and reduce overall food intake.
