I am 5'6 and weigh 150 pounds. I have been working out for four months consistently. I was eaten a lot of protein and drinking protein shakes. I have gotten bigger, but I feel like I am getting fatter in the lower stomach area. I did have a visible six pack, but now only four abs are visible. I have cut back on eaten hoping it would make the fat go away. Now, I am losing my muscle more than I expected. I need advice on what I need to eat and what vitamins to take to keep my muscle, but to loose any fat that I have.
