Is the Atkins Diet ok?

Ok, I am a type 2 diabetic that has struggled with keeping my sugar down and getting healthy. I am overweight, about 60-80 pounds too much. I have been doing the Atkins diet for the last 8 days and have lost around 12 pounds. Is it ok to continue doing this for around 3 months or so, until I lose a good amount of weight, then change my lifestyle to where im eating smaller, healthier portions, and also working out, I am working out now. Thanks in Advance
