You need to get some calipers and determine what your actually BF%. The way I tell if I am dieting to "extreme" is by testing my bodyfat on a weekly basis and if I am loosing to much lean body mass i'll increase cals or decrease cardio. Scale weight may not change much but if I am dropping BF I know I am on the right track then.

I think you are to low for 9 weeks out , this is too much like rushing imo. My wife and I start prep 20 weeks out so that we do not lose a ton of muscle, that and the first 2 to 3 weeks are slow progress wise and than your metabolism speeds up and you start burning , but 150 grams of carbs to do 60 mins of cardio , plus training, plus im sure you work and are on your feet all day etc that's a very low amount. The last 2 weeks should be minimum being on your feet and running around because you will hold more water in your legs due to inflammation that's what I was taught. To be at your starting point if you were 16 to 18 weeks out would be optimal , and the last 4 to 6 weeks would be minor tweaking so that peak week would be an all out success, if your not at a low enough bf and you haven't been dieting out for 18 weeks prior peak weak will be tough and you will come in too flat from crashing your carbs or you will come in too smooth, because when you go into your last week you should be working out Monday through wens having thurs and fri to recover , than fri night start your carb up for your Saturday show. Theres a science behind it, for example if your class roughly goes up around 3 or 4 pm for pre judging all your prior days of diet for the past few months should be designed so that your carbed up for that time so your body is already in tune with this. When you try to rush things like this and throw your body into something so drastic it will fight back and hold bf due to coming down too fast diet wise. You can take my opinion for what it is , im just trying to help and wish you the best.

EDIT: just saw your pictures! didn't realize you were going for physique. You look better than your stats say, but if you could find a show that gives you an extra 4 weeks of prep then I think youd KILL IT!

Are you going for figure or bikini? If you are going for figure youll definitely need more time, if bikini then you might have just enough time but come in with a softer look (depending on the judges this may be a good or bad thing).

I think you started a little late IMO

if you were 23-25% I would have suggested a 20 week prep or at least getting down near 18% before starting a prep. I try not to let the female competitors I work with go above 19-20% bf.

as a male and bigger than you (usually around 225lbs 15-16% bf) but trying to get to 195lbs 3-4%
My coach is a firm believer in high protein/low fat/moderate carb diets. He pulls carbs or adds cardio depending on how fast I lose weight.

It seems that you are doing a lot of cardio 60min fasted every day! and at very low calories

im currently down from 225 to 212 but calories are still about 3200-3300. Cardio 6x a week but less than half the time you are doing It for.

IMO choose a show that's a later date. if youre at 18%bf and only 1500 calories you will more than likely be burning muscle along with your fat.

I have bikini girls that I help with prep (that are on stage at 115-120) and they are at higher calories than you throughout their prep. Typically beginning prep around 2200 and ending around 1500.

STATS:
173 lbs at 25% = 43 lb fat 130 lb lean
163 lbs at 18% = 29 lbs fat 134 lb lean

That is great progress, but I think you need more time.

GOOD LUCK and keep us posted!!
