Is your purpose health/personal-desires, or competition?
If competition isn't the reason, then in your circumstance -- having dropped from 300 lb to 188 and now seeing the body highly resistant to further fat loss -- my advice really would be to train for strength and muscle for at least the next six months while not worrying at all about dropping more fat, but being sure not to add new fat. You can hold the line at this weight plus or minute a small amount to account for fluctuations, but don't let yourself, seriously, drop substantially below where you are now.
I don't know the mechanism where the body operates as if it had a set-point for bodyweight but this absolutely does seem to exist.
My expectation is that your body is not now using your present weight as its setpoint, but "thinks" it should be some considerably higher weight. When this is the case, fat loss becomes much harder and lean mass tends to be lost instead.
Allowing your body time at the lighter weight typically results in a readjustment where the body will no longer consider loss of some fat to be a major departure from setpoint.
Now of course if you've been at this weight already for the last year, then none of the above would apply.
