So we neglected to state how old you are, but overall I'd stick with a diet that keeps your weight right around 185-7 at first while you do the first month of LP like your life depends on adding weight to the bar every session. After that, we may consider pulling carbs by 20-30g but honestly- my money is on the probability that if you were to weigh/measure and be compliant with about 2500kCal day in and day out for 3 months whilst training your ass off doing strictly the novice/advanced novice LP that you'd look like a different person on the other end of it.
