You need to drop cals to below maintenance to cut effectively but for some, it is possilbe to lose body fat while gaining muscle. This is the testimony of many while using Fina. I think that by staying right at maintenance you could have a good chance, depending on your metabolism, to accomplish this as well while on some 1T/1, 4 or some 3 Alpha.
In general however your diet and your routine (for many) does change while cutting. Many people add in small amounts of cardio as well to the routine when usually they do none.
