Trying to lose weight? According to one study, eating half a grapefruit before each meal may help you slim down faster, thanks to the fruit’s fat-burning properties and its beneficial effect on blood sugar and insulin levels. Grapefruit is also hydrating, filling, and packed with immunity-boosting antioxidants.
For a well-rounded breakfast, pair it with protein—such as yogurt or an egg, Giovinazzo suggests. But check with your doctor first if you take any medications, as grapefruit and grapefruit juice can interfere with some prescription drugs.
