I need help. I'm confused. Please respond

So right now. I'm cutting and I'm thinking of bulking in about a week. Right now am around 12-13 % body fat. So my question is why do I need eat a surplus to build muscle. Thnx

    The Muscle has to be created from something. Physics, Dear Watson. Physics.

    Essentially this. Without additional energy, how would one grow?

    Be basically said it all. Everything needs to be made from something.

    Think of it this way: You have a 3-foot high brick wall in front of your house (your existing muscle mass). You want to make it into a 5-foot high brick wall (add muscle mass). Problem is, somebody is coming and stealing bricks from your 3-foot wall every night (calorie deficit), and you don't have any money (calories/protein) to buy enough bricks to even replace the ones that are being stolen, let alone buy more bricks (muscle) to build the wall higher. How are you going to build that wall (muscle) up without more bricks (calories/protein)?

    If you're going to build something, you need building materials. Calories and protein are the building blocks of muscle.

    To give a much abridged version, your skeletal muscles are the only ones that build up a substance called AMPK that actually reduces synthesis of protein in skeletal muscles. The two main ways to overcoming this are to workout and to eat more. Working out creates a powerful varient of IGF-1, called MGF, locally but also increases AMPK so you need to eat more to overcome this as IGF-1 and leucine are the main systemic compounds to overcome the AMPK buildup in your muscles. It is possible to eat at a very small deficit and gain some muscle but it's really hard so just eat a little more and you'll have to do a bit of a cut but it's not a huge deal.

    because you can't build a 5000 square foot house if you only have the materials to build a 2500 square foot house...
