The main premise of the Atkins Diet is to limit the intake of carbohydrates so that the body burns off fat instead of sugar. When a person consumes sugars and carbohydrates, blood sugar levels fluctuate and the body burns off sugar while storing fat. The Atkins Diet reverses this process.
The Atkins Diet focuses on the consumption of vegetables high in fiber, protein including meats and nuts, and low-glycemic fruits. Legumes, such as beans or peanuts, and whole grains have a higher carbohydrate content, so followers of the diet limit or even eliminate these foods. The Atkins Diet does not allow sugar, refined flour and trans fats.
While some diets focus on limiting overall calories, the Atkins Diet is designed to change the body's metabolism of sugar through limiting the specific types of foods that elevate blood sugar. There are numerous clinical studies that support the fat-burning methods used in the Atkins Diet. By keeping blood sugar levels stable, the body no longer has extra sugar to burn off. This allows the body to burn fat instead of sugar and reduces overall body weight.
The Atkins Diet offers a variety of ways to personalize the diet and attend to a dieter's specific needs. Atkins 20 is a plan for those who have more than 40 pounds to lose, while Atkins 40 is a plan for those who have fewer than 40 pounds to lose.
