I think that you should keep doing whatever works for you!! Having a weight to work towards is a good way to work towards something but at the same time continuing to lose and work towards a smaller, fit body is just as rewarding!!!
Congrats on the weight loss though!
You're almost in the 100's!
Body calculator says you should be around 154 for your height and age but I never trust those things, your body type, bone mass, all of that should be weighed in too!
