If you've been in and out of a weight loss program, you know that losing a lot of fat and gaining a lot of muscle at the same time is very hard to do. You have to have a proper diet program in order for you to do that. We often mistake cutting back on food (protein especially) to help us lose the pounds without realizing that we are also losing muscles in doing so. You want to know how to build muscle fast and lose unwanted pounds at the same time? Movie stars with great-looking bodies didn't do it without help so don't get jealous because you too can have that body. If you're ready to get started, you'll need to do a little work and a little "magic" on your diet and weight training program.
