I started Atkins and Curves on the same day. Yes, I was concerned being so heavy and working out, being tired, etc., but I stuck with it. IMO starting both at the same time complimented each other. The results are:

In 11 months:

I have lost 59.5 inches
81 pounds

Started at 276, now at 195...

I started in a size 24...now wear a size 16/Misses Large. NO MORE PLUS SIZES FOR ME!

I had to have my wedding rings sized...I went down 2 ring sizes too!
