A bit, but this effect is often overstated for fatties.  Every pound of lean muscle mass you add takes a lot of work and only uses ~10 calories a day.    It helps in the long term because 30+ pounds of muscle mass makes a nontrivial difference in your BMR, but on the short term it's negligible.  In other words, building muscle mass can help you keep the weight off but it won't help you lose it at any decent rate.
