Many Britons enter the festive period ready to pile on a few pounds, but there may be ways to minimise the side effects of festive indulgences. Five foods could help Britons control their Christmas appetite as effectively as popular weight loss drugs like Ozempic and Wegovy, a nutritionist has shared.These seasonal favourites naturally boost levels of GLP-1, a hormone that signals fullness to the brain and helps control appetite, according to Professor Franklin Joseph of Dr Frank’s Weight Loss Clinic.The foods work similarly to weight loss medications by slowing digestion and increasing feelings of fullness.Turkey is a particularly effective weight loss stapleGETTY”GLP-1 signals fullness to the brain, which is why certain foods that boost this hormone can help curb appetite, especially at Christmas,” the expert explained.While Ozempic can supplement GLP-1, adding these foods to holiday meals offers a natural alternative.Turkey, a Christmas dinner staple, is particularly effective as a lean protein that promotes GLP-1 release.”Protein takes longer to digest, keeping GLP-1 levels elevated and reducing hunger,” noted Joseph.Cranberries also play a key role, with their high fibre content helping to raise GLP-1 levels.”The fibre in cranberries not only promotes GLP-1 but helps balance blood sugar, preventing hunger spikes,” Joseph explained.Chestnuts offer another natural way to boost GLP-1, as they’re rich in fibre and complex carbohydrates.”Chestnuts offer fibre and steady energy, preventing overeating later,” the professor pointed out. The fibre in Brussels sprouts promotes fullnessGETTYBrussels sprouts also support appetite control through their high fibre content, with Joseph noting: “These veggies are fantastic for managing appetite because their fibre content helps keep you feeling fuller for longer.”Cinnamon rounds out the list of natural GLP-1 boosters, helping to regulate blood sugar levels.”Adding cinnamon to your meals has metabolic benefits and helps the body process sugars more efficiently, keeping GLP-1 levels balanced,” noted Joseph.He recommended sprinkling it on oatmeal, baked goods, or coffee for a festive and health-supportive addition to holiday meals.
