Why is cardio important?

[/ QUOTE ]

I personally don't know whether it is or not. Once I drop a few more pounds and get to the desired weight, I wonder whether lifting without cardio (except for tennis) will suffice just to maintain my weight. I suppose this depends upon whether I stick to my current high-protein, low carb approach. And even if my diet stays the same, I guess I can't really know for sure whether cardio or HIIT will be necessary for weight maintenance until I try SS alone.
