Less kcals on non training days?

[luquillo78]

I'm eating 3100 kcal ED. Same amount on training and non training days. My question is if should I take less kcal on non training days? I'm gaining weight, about 2 lbs per month, but I think that maybe it's half muscle half fat. I was asking if by reducing the kcals on non training days maybe I could keep de BF as low as possible.
The 3100 kcal came out with the "harris-eliot" excel program for a moderate activity level (training 3-5 days per week).

I'm eating about 1250 kcals from proteins, 1250 from carbs and the rest from fats.

Stats:
27 years old
5'8
158,5 lbs
bulking natural

Please advice!

I'm posting the excel program I used to calc the kcals.
