The Atkins diet is a well known low-carb, high protein diet. Its fame comes from the fact that it allows you to eat all the protein and fat that you wish to eat and still loose weight. It claims that without carbohydrates you will loose weight. This process is a metabolic state called Ketosis. Ketosis is where the bodies carbohydrate levels drops so much that your muscles have to burn body fat to give you energy.
To start with nearly all carbohydrates are cut out from your diet, except certain vegetables, steak and eggs. Then in the following weeks you reintroduce carbohydrates to your diet little by little until you no longer loose any weight so as to know your limit for loosing weight.
This diet has been criticised by many specialists who suggest that it can put a huge strain on the body and especially the kidneys. It also has few success stories. People who have participated in this diet say that the initial weight loss is great but does not last. Some essential nutrients are restricted and the diet does not reach nutritional needs, meaning that a severe lack of vitamins could occur. Obviously when there is a high protein intake, there is more risk to the heart.
