What is a ketogenic diet?
A ketogenic diet, often referred to as keto, is a high-fat, very low-carbohydrate eating plan that has gained popularity for its potential weight loss benefits. By drastically reducing carbohydrate intake, typically to less than 50 grams per day, the body enters a metabolic state called ketosis. In ketosis, the body starts burning fat for energy instead of glucose from carbohydrates, producing ketones as a byproduct. This shift in fuel source can lead to appetite suppression, increased energy levels, and reduced cravings. Popular keto-friendly foods include avocados, nuts, fatty fish, eggs, and leafy greens, while fruits, grains, and sugary beverages are strictly limited. While the keto diet can be effective for some, it’s essential to consult with a healthcare professional before making any drastic dietary changes.
How does a ketogenic diet work?
A ketogenic diet is a highly effective eating plan that has gained significant popularity in recent years due to its impressive weight loss results and potential health benefits. By drastically reducing the intake of carbohydrates and replacing them with a diet rich in fats and moderate protein, the body is forced to enter a state of ketosis – a metabolic process where the liver converts stored fat into molecules called ketones, which are then used as a primary source of energy instead of glucose. When carbohydrate intake is low, the body can no longer use glucose for energy, and as a result, it begins to break down fat cells to produce the much-needed ketones. This shift in metabolism has a profound impact on the body, leading to increased energy levels, reduced inflammation, and improved mental clarity. To achieve and maintain a state of ketosis, it is essential to follow a well-planned ketogenic diet, which typically consists of 70-80% of daily calories coming from fat, 15-20% from protein, and only 5-10% from carbohydrates.
What does a low-carbohydrate diet entail?
A low-carbohydrate diet, also known as a low-carb diet, is a type of dietary approach that restricts the intake of carbohydrates, such as sugar, bread, and pasta, in favor of protein-rich foods and healthy fats. This eating plan entails limiting or avoiding foods high in carbs, like grains, starchy vegetables, and legumes, and instead focusing on whole, nutrient-dense foods like lean meats, fish, eggs, dairy products, and non-starchy vegetables like leafy greens and broccoli. By drastically reducing carb consumption, the body is forced to switch from relying on glucose (sugar) for energy to burning stored fat for fuel, a process known as ketosis. A well-structured low-carb diet can be an effective way to promote weight loss, improve blood sugar control, and enhance overall health, especially for individuals with insulin resistance or type 2 diabetes.
