A low carbohydrate diet, often abbreviated as low-carb, is a nutritional approach that restricts the intake of carbohydrates, emphasizing foods high in protein and healthy fats instead. This dietary strategy typically limits carb consumption to around 20-150 grams per day, significantly lower than the average intake in a standard diet. The primary goal of a low carb diet is to reduce reliance on carbs as the body's primary fuel source, prompting it to enter a metabolic state called ketosis. In ketosis, the body burns stored fat for energy, leading to efficient fat loss and potential weight management benefits. Foods allowed in a low carb diet typically include lean meats, fish, eggs, non-starchy vegetables like leafy greens, nuts, seeds, and healthy fats such as olive oil and avocados. Conversely, high-carb foods like bread, pasta, rice, sugary snacks, and some fruits are restricted or limited. Advocates of low carb diets suggest benefits such as improved blood sugar control, reduced cravings, and enhanced satiety due to stabilized insulin levels. Moreover, some studies indicate potential advantages for individuals with conditions like diabetes, metabolic syndrome, and certain neurological disorders. However, it's important to note that individual responses to low carb diets can vary, and some people may experience initial side effects like fatigue, known as the "keto flu." Consulting a healthcare professional before starting any significant dietary changes is advisable, especially for those with underlying health concerns.
