While its possible to lose fat and gain muscle at the same time, it is extremely difficult, since you need a surplus to gain weight and a defecit to gain muscle, to repeat evrything LD has just said

. I would eat to maintain muscle mass, and see if your lifts keep going up or not, or wheather you make signifcant body comp changes...if either is not to your satisfaction...reevaluate and try it again...i found the best way i got results was to experiment and find what works for my body the best, after all not everyone will respond the same to the same stimulus
