I don't know...this formula puts me at just above 4%. I don't think that is possible. :noway:

I think you made the mistake I first made. Reread this line: "Lean Body Mass Factor 1 + Factor 2 - Factor 3 - Factor 4 + Factor 5". They're not all plus signs.

Haha!! You're right...that's what I did! I knew I had to have done SOMETHING wrong to get 4%!!! Thanks!!

Thanks for this!! I added all the factors first too, but once I fixed it I was much lower in body fat than I thought I would be! :laugh:

Ack! Fitwatch looks like the proper successor to Nutrawatch which was my favorite cal tracker of all time. I may have to switch. :sad:

This website gave the same BF% as the formula listed if anyone is curious!

Or you could use one of the dozens of bodyfat calculators on the internet and use one of them. A whole lot easier

Bingo!

Except most of them do not take build into account.

Being the nerdy engineer that I am, I converted these to spreadsheet formulas that automate the process and give color coded indications of where you stand.

Message me, and I'll try to send it to anyone interested.

Yea the not taking into account your size is the reason I posted that one...all the other ones are lame in my opinion. Every BODY is different and it needs to take into account different things. Like the one I used to use that says I am Obese with a healthy waist line...ummm ok. So am I healthy or obese?

Wow, so the body fat scale I just bought recently is like 10% more than this calculation and the calculators online..is the scale that far off? I thought it must be, since I find it hard to believe at 140lbs I'm obese as my scale would indicate.

The formula for men can be reduced to just one line:

-0.082 - 94.42/[Weight] + 4.15*[Waist]/[Weight]

FWIW, I measure my body fat on a BIA analyzer and it says I'm about 18-19%. This tells me I'm 19.7%. Whatever, still interesting to look at.

Ha, using that formula, I decided to see what my waist would be if I went down to 11% body fat while losing only fat and maintaining the same lean mass. It calculated my waist to be just a hair over 30, which is what pants I wore when my body fat was that low. Interesting!
