Probably not. This is a weight loss method, not a muscle gain method. In fact, you will probably lose some muscle along with the fat. Whether that's something you're willing to accept is up to you. Personally, I don't think putting the muscle back on is all that hard - but losing the fat was almost impossible previously. You can do exercise on the "big breakfast" approach - but you'll find it much easier to do so in the morning. I doubt you'd gain much muscle while in a 500-1000 daily calorie deficit, but you could certainly help maintain it, and after a nice big breakfast you wouldn't be short of energy to lift weights.
