Since your cutting you should get 10-12 calories per pound. So you should aim for 1600 calories a day.
go for
200g of Protein (800 calories, 50%)
140g of Carb (560 calories, 35%)
26g of Fat (240 calories, 15%)
I agree with Hazballs that working 6 days a week is hard. For 12 weeks, you will end up getting very bored, unmotivated and results will be just the same if you go on a 4 maybe 5day workout week.
Go for 2days workout, 1day off, 2days workout 2days off. This should be a very good way. If your doing HIIT Cardio, dont do more than 30min, your muscles will be ripped apart.
Goodluck dude! Im in the exact same boat as you.....
