Will I achieve a sub-17 BMI? I can't seem to break past 18.6 and I want a slimmer waist and thinner thighs, it's killing me.

Get a body fat scale. BMI isn't a good metric. Also low/no carb + intermittent fasting is the best bet for reducing body fat. You don't want to lose muscle mass.

I want to so bad but they're expensive. I've already lost a lot of muscle mass I think, I've lost 60 lbs this year 

Thank you
I mistyped btw, I want a sub 18 BMI, I think 17.5 is ideal. Still healthy by asian standards, I can fit in their smalls.. I think I just need to eat smarter if I want it since I've found I'll plateau but I'll eat like a normal person for a night and find I dropped 2 lbs.
