Typical foods for a low-carb diet. In general, a low-carb diet focuses on proteins, including meat, poultry, fish and eggs, and some nonstarchy vegetables. A low-carb diet generally excludes or limits most grains, legumes, fruits, breads, sweets, pastas and starchy vegetables, and sometimes nuts and seeds. Some low-carb diet plans allow small amounts of certain fruits, vegetables and whole grains.
Other diets (Atkins, South Beach) don't allow fruit at all in the first phase. Not all low-carb diets limit fruit, however. Diets like the Paleo diet, Whole30, and even Weight Watchers (although it's not necessarily a low-carb diet) do not place a limit on fruit. In general, if you are following a low-carb diet, you should try and eat fruits that are low in sugar.
