That's a pretty difficult path to follow. Chances are you'll end up not eating enough, and start burning muscle in addition to fat. If you lose more than about 1 kg / ~2.2 lbs a week, you're at risk of doing just that. On the other extreme, you can easily wind up eating too much, and gaining more than fat than actual muscle. To really know what's going on, you'd of course have to measure actual body fat lost, rather than just weight lost. Muscles weigh more than fat, some build muscle more easily than others, etc. Generally I'd say there's a reason most body builders bulk up for months, then spend time dropping excess weight, rather than aiming for a steady increase in muscle mass with zero fat gain. For the most, my experience is that aiming for slow weight / fat loss through any muscle exercise is also bound to provide some muscle build up. That seems adequate for most people.
