Do understand that it's definitely not muscle gain. The most you can hope for while eating at a deficit is the preservation and improvement of the quality of the lean muscle you have. It's nearly impossible to build measurable amounts of muscle mass at a calorie deficit. You need a calorie surplus to do that, and even then it takes months or years... not days. :)
So while kind-hearted people often tell you that it's muscle gain, and muscle weighs less than fat, that's not what's happening here.
Your weight isn't a static number... it goes up and down throughout the day and week. :)
