Hitting protein macros

Hey,

I feel like this is something I should really know the answer to, but google is conflicting and my brain is tired. Anyway...

I'm wondering how important it is to be hitting my protein goal every day? I know the importance of protein for muscle growth and repair, but at the moment I'm not doing any strength training, but obviously I don't want to lose any of the muscle I have so I'm guessing that eating protein is pretty important.

At the moment I'm eating 2000 calories. I used scoobys calculator to get this figure as I do insanity max30 5x per week, kickboxing 2x per week and I have a fairly active job. I weigh 183lb/170cm/29yo female (incase you wondered!) I am set to lose 1lb/week and macros are set at carbs 40% protein and fat 30%.

So at the moment I'm not hitting the protein, it's more carbs. Looking back at my diary over the last few days (since I started insanity and increased my cals) I've eaten an average of 120g per day. Should I add in a protein shake after my workout or is it not so important that I hit the protein ratio given that I'm not strength training right now?

Thanks.
