Summarize this article:

If you want to try a low-carb diet that has been around for a while, then the Atkins diet is a great choice. This diet also claims that it will help you lose 15 pounds (6.8 kg) in the first 2 weeks, so Atkins is a great plan if you are hoping to drop a large amount of weight quickly. The South Beach diet was developed by a cardiologist and it claims to help you develop a healthier way of eating while also promoting weight loss. Also, the South Beach diet does not restrict carbs as intensely as some other diets, so it may be easier to follow and stick with it. This diet plan focuses on getting your daily intake to 75% fat, 20% protein, and 5% carbs.  This will force your body to use fat for energy and promote quick weight loss.  A ketogenic diet has long been known as beneficial for people with epilepsy. However, following the diet may also help to prevent Alzheimer’s, stroke, dementia, and traumatic brain injury.  Some people experience negative side effects as they transition to a very low-carb diet, such as brain fog, fatigue, and moodiness. The Dukan diet is one of the most structured low-carb diets, which some people find helpful. In the first 10 days of this diet, you only eat lean protein, oat bran, and water. After that you can include non-starchy veggies, a serving of fruit, a serving of whole grain, and hard cheeses. You may lose 10 pounds (4.5 kg) or more in the first couple of weeks, and then about 2 pounds (0.91 kg) to 4 pounds (1.8 kg) pounds after that. Keep in mind that any time a diet has a lot of restrictions, you are at risk of nutritional deficiencies. You cannot have any dairy, grains, potatoes, or processed foods on this diet, but you can eat lots of meat, veggies, roots, fruits, and nuts. The whole foods approach of this diet is healthy and you will get to eat plenty of food to stay full and satisfied.  The goal of the Paleo diet attributes many of the health issues people have today, including obesity, with the modern agricultural diet that includes dairy and grains.

Summary:
Select the Atkins diet for a classic low-carb diet. Choose the South Beach diet to develop healthier eating habits. Try the Ketogenic diet for a high-fat, satisfying meal plan. Do the Dukan diet if you like structure. Opt for the Paleo diet if you want to emphasize whole foods.
