six pounds in ten days?

is this possible? thinking about going on the south beach diet to lose the weight. any advice?

Not possible to do in a healthy way.  At least not unless you are very, very overweight, or retaining 4 pounds of more of water. 

It is only possible to lose fat at about 1% of your body weight per week.  Losing more than that means you are losing muscle.  That's nor usually a goal for most people. 

The fact you had to ask shows you know this isn't healthy. Lost the six pounds over 5 - 7 weeks, using CC + exercise. Then, it's way more likely to stay off.

Why would you want to do this.  You have all the tools right here.  I agree with kiltias92.  Don't spend the money, honey.
