Can building muscle help you lose weight? Absolutely. For every 10 pounds of fat you burn 500 more calories each day. Added up over a week you have burned 3500 extra calories. This puts your body in a deficit. Which leads to you losing one pound per week.
Now as you begin to gain muscle right off the bat you won’t see much change in your weight. Sure you are going to be losing fat, but gaining muscle will result in not many changes to your scale right off the bat. But stick with it. This is a process. It doesn’t happen overnight.
So keep lifting, this is going to change you. You will get those muscles you want and lose the fat. And as you do lose the fat, those muscles will start popping.
