Stuck in a rut? Persistant wt stall

mtnmuse

I am a sr disabled lady living in a rural mtn state. Most of my life i have been over weight to morbidly obese.
I managed to drop from a high of 234* to lowest adult wt of 141. The usual restarts but never to t hff e previous higer ranges.
Now for the past 3 yrs stuck around 160
Its like maintenance instead of wt loss.
average.
Grrr
Really struggling to regain some momentum downward -again.
