So i know this chick who is the same height as me (5'5) and weighs about the same (180). The only difference is i have fat thighs and a belly and she has a pretty flat stomach and slim thighs. Nice's arms ect. She lifts weight's. With that being said if I continue to lift weights and do cardio should I be less concerned about the scale and more focused on the measurements? I plan on replacing most of my fat with muscle.

    Muscle does not weigh more than fat. A pound of fat weighs the same as a pound of muscle.

    Muscle is more dense, taking up less space in the body hence a muscular person could weigh the same as a person who is flabby but look completely different. Fat is spread out further in the body.

    No. A pound of muscle and a pound of fat weigh the same. What most people mean when they say that is that muscle is more compact and dense than fat. And yes, if you focus on body recomposition you can trim the fat down.

    If you continue to lift weights using progressively heavier weight, and do cardio, and are not eating at a surplus, you will let smaller looking. If you are also eating at a small deficit (small, to support your maintaining muscle mass), you will reduce body fat as well. The key to the weight training, as I see it, is to move beyond a gazillion repetitions of light weights that isolate muscle groups and into full body lifts.

    You can't replace fat with muscle.

    Yes, for a given volume, muscle weighs more than fat.

    If you are eating at a deficit, the scale is a fairly good meter of how you are doing in terms of fat loss. If you are eating at maintenance (or surplus) and lifting heavy, I would rely more heavily on the tape measure.

    Yes muscle, by volume, weighs more than fat, by volume.

    Since you compare things of the same volume to determine if something weighs more than something else the "by volume" is implied.

    All this means is that muscle has a higher density than fat.

    Because of this fact

    Muscle, by weight, takes up less volume than fat, by weight.

    In this case I can take 1lb of muscle and 1lb of fat and observe that the lb of muscle looks smaller even though it weighs the same.

    These are two sides to finding the same information which is which object is denser. In this case it is still the muscle.

    One day this thread is going to happen and people aren't going to correct what doesn't need correcting

    PEOPLE KNOW THAT THE OP MEANS BY VOLUME ...

    eat at a calorie defecit and lift heavy

    Once you've lost enough body fat, eat at or above maintenance and lift heavy

    +1 to all of that but especially the first part.

    Will people please get over this thing of telling people that muscle doesn't weigh more than fat? It does no good to point out that a pound of fat weighs the same as a pound of muscle. That's like saying that a pound of lead weighs the same as a pound of feathers. Of course that is true, but they take up different amounts of space. That is all people mean when they say muscle weighs more.
