How to Calculate Lean Body Weight Formula


body fat measurement

body fat measurementWant to calculate your lean body weight and the amount of fat you still need to lose to achieve your desired lean body mass? Here’s an easy formula to help you calculate this in no time at all.

All you need to perform these calculations is your current body fat percentage. This is the total percentage of fat in your body and includes body fat as well as essential fat. If you’ve never checked your body fat levels, we suggest a simple pair of AccuMeasure fat calipers which can be had for less than $10.

If you know your body fat percentage already, you’re one step ahead of the game. Here’s the formula you need to shred all the body fat you desire and look lean and ripped this year.

The Formula:

Desired Body Fat % = Current Lean Body Mass  / Desired Lean Body Mass

First, make note of your current body fat percentage.

Let’s say you’re 200 lbs and 20% body fat.
200 x 20% = 40 lbs of fat. Your lean mass in 160 lbs.

Your wish to be 9% body fat so that you can really show those sculpted abs off and look like Wolverine.

Take your lean body mass and divide by 91%
(you want to be 91% lean and have 9% fat).

160/.91 = 175.8. This is the weight you would need to achieve to be at 9% body fat (assuming no loss of muscle).

Now, calculate the time it will take you toe reach your goal when losing 1-2 lbs of fat a week. The slower you lose weight, the more muscle you maintain and the better chance of keeping the weight off.

And finally… Eat right by calculating the amount of daily calories you need and workout hard.

    I’ve been overweight all my life and tried so many things. Different things work for different people and I was lucky enough to find one that worked for me. I lost 25 pounds in one month without exercise and it’s been a life changer. I’m a little embarrased to post my before and after photos here but if anyone actually cares to hear what I’ve been doing then I’d be happy to help in any way. Just shoot me an email at oceanflowers82@gmail.com and I’ll show you my before and after photos, and tell you about how things are going for me with the stuff I’ve tried. I wish someone would have helped me out when I was struggling to find a solution so if I can help you then it would make my day
