I have done Atkins also and can attest to its effectiveness. First google it and learn all about what happens. Yes you will bonk a little in the first day or so, but the body is very effective at compensating. It starts to burn fat to make up for the lost carb sourced glycogen. It does not go into survival mode because calories are still going in.

My experience...works well but is not a true lifestyle. Use it to jump start the weight loss and then change your eating habits and exercise routine to maintain a healthier lifestyle.

Now if I could only cut out all those beers......
