Low carb diets have gained popularity for their potential to promote weight loss and stabilize blood sugar levels. These diets, which restrict carbohydrates found in foods like pasta, bread, and sugary items, emphasize protein, fats, and vegetables. While guidelines can vary, the core principle involves limiting foods high in carbs or added sugar. This article delves into the details of a low carb diet, including what to eat, what to limit, examples of popular low carb eating patterns, and a sample menu.
Understanding Low Carb Diets
Low carb diets have been associated with several health benefits, particularly in supporting weight loss and managing blood sugar levels. The amount of carbs permitted each day can vary depending on the specific type of low carb diet. Typically, a low carb diet contains less than 26% of total daily calories from carbs. For someone consuming a 2000-calorie diet, this equates to fewer than 130 grams (g) of carbs per day.
While low carb diets generally limit foods high in carbs or added sugar, the specific foods allowed can vary based on your daily carb allotment. Even higher carb foods like fruits, starchy vegetables, and whole grains can be incorporated in moderation into some low carb diets.
Popular Low Carb Eating Patterns
Several popular low carb eating patterns exist, each with its own approach to carb restriction:
Ketogenic (keto) diet: This high-fat, very low carb diet limits daily carb intake to less than 5-10% of total calories, or around 20-50 g of carbs.

Atkins diet: The first phase of this diet restricts carb intake to about 20 g per day, depending on the chosen plan. Over time, the intake gradually increases but usually doesn’t exceed 100 g per day.
South Beach diet: In addition to reducing carb intake, this diet promotes lean meats and heart-healthy fats. During the initial phase, grains and fruits are also restricted.
Paleo diet: Mimicking the eating patterns of hunter-gatherer ancestors, this diet is naturally low in carbs.
Dukan diet: This diet restricts carbs while emphasizing high protein and low fat intake. It’s divided into four phases to help individuals reach their weight loss goals.
