See the gadget/widget on the bottom right?

The one with the virtual model in the red dress? I'm a bit pudgier than that, even though I popped my height and weight accurately into the page.

Notice how the model's shape doesn't change until it loses 48 pounds.

Now THAT is accuracy! I had to lose 50 pounds before I saw any change in my body shape when I went down from 296 to 245, and it was still barely noticeable. I wore the same size clothes, they were just a bit looser. Now that I'm 30 pounds higher, 8 years older, menopausal and officially hypothyroid, my clothing size is larger than it was at 296 because the weight didn't go back where it came from, it went to the butt and waist, instead.

I should have left well enough alone.
