What does a "low-carb" diet typically limit?

A "low-carb" diet typically limits foods high in carbohydrates. The primary goal of such diets is to reduce carbohydrate intake in order to lower insulin levels, promote fat burning, and support weight loss or management. Foods that are high in carbohydrates include grains, legumes, sugars, starchy vegetables, and many fruits. By limiting these foods, individuals on a low-carb diet can help stabilize their blood sugar levels and promote overall metabolic health.

While a low-carb diet may also influence the consumption of fruits and vegetables or potentially lead to a higher emphasis on protein-rich foods, the defining characteristic is the significant reduction of carbohydrate sources. This approach can vary in how strict it is, with some low-carb diets allowing for certain amounts of fruits and vegetables, depending on their carbohydrate content.
