Im 14% bodyfat and i weigh 170 pounds..does this mean my fat weighs 23.8 pounds?

the way i figure it out is 0.14 x 170 = 23.8 is this the right way to find out how much your fat weighs?..or is there more factors

also (if my method is corect) if i were to loose 16.6 pounds id be 6% bodyfat?
23.8 lbs of fat is correct.

getting down to single digit body fat for the first time is very, very hard for most. the lower the body fat percentage the harder it is to lose fat. the amount of body fat that we all have is regulated by a hormone called leptin found in fat cells. it tells the body how much fat it has.
Yes, your calcualtion are correct. The way you have used the formulas to calculate the weight of your overall fat works out, and I suppose if you lost about 17 pounds you would lose 6% of body fat. However, if you are planning on losing weight, than you shouldn't really think about losing weight that way. You ned to know your weight goal, and go for that, instead of focusing on your BMI and overall fat. However, if you are planning on getting healthier, than that is probably the best way to lose the weight.
If you have 14 percent body fat and you weigh 170 pounds, that does mean your fat weighs 23.8 pounds.

The actual equation for calculating percent body fat is:
% body fat = 100 - (100 * lean body weight)/total weight

However, I don't thing you could calculate this correctly with the only information being a loss of 16.6 pounds accuratlely, unless you are assuming that those 16.6 pounds of lost pounds are purely lost body fat (and nothing else like water weight and so forth). However, if we were assuming this, then:

% body fat = 100 - (100 * [(170-23.8) - 16.6])/(170 - 16.6)

I subtracted 170 and 23.8 to get the initial lean body weight, and subtracted 16.6 to it to get the new lean body weight.

I subtracted 170 and 16.6 to get the overall new body weight

% body fat = 4.802
Your method is correct. It's just that simple calculation. The rest of your weight is muscle, organs, bone, water, etc. 14% body fat is great! at 6% body fat and losing 16.6 pounds you'd be only 153.4 pounds and have only 9.2 pounds of fat.

As a guy, 6% body fat is totally doable and healthy. Women need more body fat to stay healthy or else all sorts of health problems occur.
Yes you have 23.8lb of fat and 146.2lb of lean mass.

However the only way you would have 6% body fat by losing 16.6lb is if you maintained all of your lean mass which is highly unlikey. When you lose weight you also lose water and some muscle, even if you do intense training and eat a high protein diet it is not totally avoidable unfortunately.
Yes, that would be how much fat (in pounds) you have on your body right now.

And if you were to lose only fat and no muscle, then you would take your new amount of fat in proportion to your new weight and that would be your new body fat % (6%).
I think that first part is right, about how much your fat weighs, however by losing 16.6 pounds you don't automatically drop to 6% body fat...you lose more than JUST fat when you lose weight, so you'd have to take your body fat measurement again then.
100% = 170 pounds
1% = 1,7 pounds
14% = 23,8 pounds

Sounds reasonable to me.

Your second question:
1% = 1,7 pounds
16,6 / 1,7 = 9,7%bodyfat loss
14 - 9,7 = 4,3% bodyfat.
Your body fat does way 23.8 pounds, but if you did lose 16.6 lbs, it wouldn't be all body fat. It could be waterweight and stuff.
sounds right to me
idk do u think ur fat
