Cut progress and evaluation

Current Weight: 142lbs
Body Fat Estimate: 20-25%. I going to worst case is and say 25% to "pad" your cut time a bit in order to account for any roadblocks
Desired Body Fat: 15%
25% * 142lbs = 35.5 lbs body fat
(35.5-x)/(142-x)=15%
> solve for x
> ~16.5lbs
Alot 1 week for every pound of fat you want to lose. Any more and you are risking muscle losses
Your cut should take roughly 4 months
this is great btw, thanks a lot

Yeah I can see how that would work. I think the whole being in better cardiovascular shape could also have a snowball effect because the body would function better as a whole.

This isn't quite right, as your LBM will also decrease while you lose weight, so to get to 15% BF% assuming you are 25% now you will most likely have to lose 18-25 lbs, depending on how much LBM you lose. A rule of thumb could be 1 lb lbm lost for every 3-4 lbs of fat lost, like on a bulk where you aim for 1:1.
So the Calculation should be more like LBM = 106.5 (.75*142) to get to 15% assuming no lbm lost you do the find for X which is about 16.5 lbs, but if you lose 1 lb of lbm per 4 lbs lost that means you lbm is now:102.5 (106.5-4), so at the 125.5 lbs (142-16.5) you will have a BF% of about 18% (1-102.5/125.5) not 15%.
If you aim for a 24lb loss, say 6 lbs of LBM that would put you at a bf% of 14.8% (100.5/118), so to get to 15% BF% you will have to lose 18-26lbs. to limit lbm loss you will want to get enough protein, take part in a progressive strength training program, and have a relatively small deficit.0 -

Yeah I figured that. Regardless,weighing 125lbs is ridiculous and I won't cut below 130lbs. At that point I'm probably just gonna look to slowly gain and cut again in the future.0 -

You are totally right. Not sure what you did with the math tho......but its an easy fix:
(35.5-x)/(142-x-0.25x)=15%
x=17.47
So really not all that different from my original estimate, adds maybe two weeks0 -

so 142-17.5 = 124.5 at 15% that would be 105.8, only a loss of 0.7 lbm, he would more than likely lose much more than that!
My math was saying for every 4 lbs lost one would be lbm (3:1 ratio), then workout out how much they would have to lose to be close to 15%, the answer was just under 20, not 17.5.
Your calculation should be
(35.5-0.75x)/(142-0.25x) = 19.9 lbs or if 4:1 would be (35.5-0.8x)/142-0.2x) 18.4 lbs

ahh. yup, I see now. Can't use "x" as fat lost anymore once you factor in lbm too. "x" becomes weight, so you have to throw the correct percent it comes out on the top and bottom of the fraction.0
