re: Intermittent Fasting

I didn't want to start an entire new thread so hopefully someone with experience can answer this. I have been intermittent fasting for a couple of years now. I use the 16-8 window basically skipping breakfast and not eating after 8 pm. I recently started working out in the morning at 5 am (have always worked out after work). Am I jeopardizing my health/gains by not having a meal until noon after doing pretty taxing HIIT, cardio, and weights? Current goal is to lose about 8 lbs and maintain strength. Current routine HIIT/Crossfit type workout 3 days a week and weights/40 minutes on open stride (elliptical style machine) 2-3 days a week.
