When trying to follow a low-carbohydrate diet, eating fruit can be tricky because they vary widely in carbohydrate and sugar content. As a general rule, berries and summer fruits have the lowest amount of carbohydrates, while dried fruit and tropical fruit are extremely high in carbohydrates. Winter fruits have a moderate amount of carbohydrates. The key to eating fruit on a low-carbohydrate diet is moderation.
One fruit that is very low in carbohydrates and high in fiber is avocado; however it is often not considered a fruit at first glance, since it is not sweet. Avocados are the only fruits allowed in Phase 1 of the Atkins Low Carbohydrate Diet. Without taking into account the grams of fiber, and assuming that the serving size is 1/4 cup, here are some fruits that contain fewer than 5 net carbohydrates per serving: apricots (3.1), cantaloupes (3), starfruit (3), cherries (4.2), coconuts (1.3), honeydew (3.6), lemon (3.8), passionfruit (2), pineapple (4.3), watermelon (2.6), blackberries (2.7), blueberries (4.1), cranberries (2), currants (4), elderberries (4), raspberries (1.5), and strawberries (1.8). Some other fruits that are a little bit higher in carbohydrates but still under 15 net grams include apples, grapes, grapefruit, kiwis, mangoes, oranges, peaches and plums.
