Why lift weights when losing weight if not to build muscles?

Ok I've read a lot of threads about it and I know it's important to lift weights while losing weight so we don't lose muscles... but I've also read that you can't build muscles on a calorie deficit (although the nurse calculated that I gained 2lbs of muscles in 3.5 months, but I was obese then and 2 lbs is really not much out of 118 lbs).

So, what's the point? Wouldn't a protein rich diet be enough to maintain our muscles then? Can someone explain to me the logic behind it?

    if your muscles aren't sufficiently challenged while you're losing weight then they will atrophy. it's possible to lose lean body mass at the same ratio that you lose fat mass so a 30 pound loss will be 15 pounds of fat and 15 pounds of LBM. a proper lifting routine will help you spare the muscle and keep the losses primarily to fat. that would be the point

    Lifting weights leads to greater amounts of fat (weight) even with no increase in muscle mass.

    Don't over think it--just lift it.

    The point is that when you do shred the fat, what's underneath it will look fantastic

    The point is that lifting heavy things will give you the shape and definition most people want. Just dropping weight through a protein-rich diet won't make your fanny look good on the beach and you could end up a skinny-fat person!

    You can gain mucle in a deficit. I'm quite noticeably larger but much leaner.

    sure you are...

    For those reading this. It _may_ be possible. but ONLY under 4 conditions

    1) you're very fat.
    2) you're utterly untrained.
    3) You used to be trained, but are now untrained for long period of time. muscle memory
    4) You're on gear

    And even then if these conditions are true, there is no guarantee. The simple fact is for most people losing fat requires a calorie deficit and gained muscle mass requires a calorie surplus. these are very opposing conditions.

    Gaining muscle does not necessarily translate into weight gain.

    Cause I don't wanna be skinny fat?

    I know I know, people hate that term. Still, that's what I *don't* want.

    of course it does. muscle has mass. thus weight will go up when you gain it.

    I've been wondering this, too. I spent three months sick in bed a few years ago and have very little muscle mass, but I don't really see a reason to try to regain it until I finish losing my weight.

    I kind of took it as getting leaner, thus having the appearance of more muscle. My bad.

    Because if you wait until you've lost all your weight and reach goal you may find that you need to eat at a surplus to gain muscle just to look how you *thought* you would look at that weight. And it's not as if gaining and building muscle is easy work--it's tough and takes a lot of hard work. It's beneficial for you to maintain the little muscle you do have NOW rather than try to rebuild it later.

    it's far easier to retain rather than rebuild...

    As far as I know (From my personal trainer, Lindora, My own research and stuff they told me in the Army) Muscle burns calories. A person with more muscle will have a higher resting metabolic rate than someone without. When you are burning fat if you do not lift weights or weight train then you will lose muscle mass and after losing the fat you want your resting metabolic weight will decrease with the loss of muscle and since you burn less calories it will be harder to keep the weight off.

    When you lift or do exercises that tire your muscles it breaks them down and the rich protien diet helps rebuild them. If you do not want to bulk up you do less weights and more reps... (That is what I do) If you want to be like Arnold was "Ill be back" then more heavy weight and less reps.

    Hope that helps. I am not professional but I have had a lot of experience and plan to get into the field of weightloss at some point so I hope this helps. That is as accurate as I can get. If anyone finds inaccurate information in here please contact me so I can make sure to learn what is true and not! ;)

    I'm fully aware that I'm going to need to eat a surplus to look good when I reach my goal weight. I'm not going to look good at my goal weight because my body behaves like silly putty and I'm going to look like a puddle of goo still. It just seems like a good benchmark.
