Losing the last 10 pounds (support needed!)

I'm on the last 10 as well, it is very slow-going. You just don't have the body fat to carry a large deficit and your tracking has to be more on the ball.

My recommendation is to set your goal for 0.5 lbs per week, and make sure to do some strength training so you retain muscle while burning fat. Not sure how everyone physically looks right now, but if it's no so much scales weight but measurements you are after, might want to consider a recomp or bulk/cut cycle. At this point the number on the scale and the body we want is not always the same thing.
