I need to buy a new scale. Is there any one under $200 (preferably under $100) that really tells you your body fat percentage and lean muscle mass in real time? Not just based on an algorithm of what 1000 people my size and weight have (such as the Tatiant scale as understand it, if I am wrong please correct me). I enjoy fasting but I am always afraid that I will lose bone, calcium or muscle (I know I have read the science!) I have started feeling shorter lately but that may just be my kids growing or paranoia. I have started to take calcium when I fast which I am not too comfortable with as the studies for SAD women do not support this. Example

I do not want to rely on tape measures or calipers because I am not comfortable having anyone else measure me and when I did measure I noticed it really depended on where you put the tape measure to get an accurate reading. Plus I like scales! Dexa scan is not an option for me. Also, it would not tell me what is happening that week as I am fasting or immediately after a fast.
One other thing, I would like my weigh in information kept private from other family members, is that possible? However that is a lower priority than being able to accurately calculate lean muscle
