Muscle weighs more than fat and you have more than likely increased your protein if you are following the recommended meal plan, so you will gain muscle. Give it time because the more muscle you have the more fat you will burn.
Preparing for my own photo session with top fitness photographer Noel Daganta, I was eating so clean and so perfect that I gained 4 pounds of muscle in a month but my body fat went down 3% yet I weighed more. This is a perfect example. Body fat % is whats important not so much what the scale says.
