I know everyone looses weight differently according to thier own body. However, I am told on the average that I will loose 60% of my excess body weight after the sleeve surgery. How close to the truth is this assumption???

I am pre-op and will be ready soon for sleeve. I am 215 now down from 232 which i was six months ago when I started the 6mos nutritional log pre insurance. Did anyone ever worry they might loose too much weight? My goal is 150, Id really not like myself less than that, I dont like the way my body would appear too skinny for me below that weight, especially my face. Anyone, had same fear? Makes me second guess the surgery aolt???
