Hi, Karen.

I calc my bodyfat on nocarbzone, and it seems to do fine for that calculation - bodyfat, not BMI. If you're ok posting your measurements, I can run them through some other sites and crosscheck for you. PM me if you like.

Another good place to check is leanandstrong dot com. Look for the link to the calculators on the left. Calculate your current bf%, then go to Optimum Weight. If you enter your current weight, current bf% and desired bf%, it will tell you what you will weigh at that percentage.

Edit: try nocarbzone again. I think you may have typo'd some of your numbers. I put in your height and weight, and to get 40%, I had to give really outlandish measurements for hips and waist (like 42 and 35). Even then the 'ideal wight' listed was 103-111.

Cheers,

Friday
