Muscle does weigh more than fat

Muscle does weigh more than fat.

I have been in training for a 10k for about 5 weeks now, going out for a run 3 times a week. Also, watching my diet on non-running days. Beer consumption is restricted to weekends only.

My clothes are looser; my beer belly has nearly gone. My face is less bloated. And when I am running I feel that I am not lugging as much weight around.

but my weight hasn't changed as much as I expected: 13st - 12st9. I was expecting around 12st4.

A pound of muscle weighs the same as a pound of fat!  Muscle is just more dense than fat.

Mike,

a kilo of muscle weighs exactly the same as a kilo of fat.  However, a kilo of muscle is more dense than a kilo of fat, so if you are losing fat and building muscle you will see the effects you describe.

EDIT: x-post, great minds and all that

Ooh, it's been a while since I saw the 'muscle weighs more than fat' debate. Cinder's has it right with 'dense'. 

Now, where me popcorn

There's another myth about muscle "turning to fat" - that can't happen either.

Muscle is more DENSE than fat therefore 1kg of fat will have a bigger volume than 1kg of muscle which explains the reduction in size but constant weight you describe.  In order to be correct you should state that 1m^3 of muscle weighs more that the same volume of fat.

Please could people learn the basics of Physics?

Or just use the laymans terms already used above

A pound of one thing always weighs exactly the same as a pound of anything else and, therefore, everything weighs exactly the same...  Or something...

It does in zero gravity

When I started training about 5 years ago I lost 1.5 stone over 3months then started to put weight back on while still appearing to lose weight.

I weigh less than I did before. It's still me. Whether my volume is different or I'm more dense is a pointless observation and difficult to measure outside of a physics lab. I weigh less.

Well yes, I suppose it is a pointless observation Tim - but what people are saying that Mike's assertion about muscle weighing more than fat is wrong - and explaining why.

23/10/2013 at 13:17

Semantics. You don't need to quantify by stating volume as that's already implied in the statement. I weigh less that the person sitting next to me.

Pulls up a chair... and pops some pringles into the thread.

How is it semantics Tim?

Mike opened his post with "Muscle does weight more than fat" - it's just not true.

His later comments about his own weight loss may or not be true, I don't know, I don't know him but the two things aren't necessarily related. He could have gone on to talk about rising gas prices or the Finnish weather and it would have been equally irrelevant to his opening assertion. 

23/10/2013 at 14:05

Isn't the point of the OP that he doesnt really weigh a great deal less than before which is the opposite of Tims situation?

Though I would make the point that extra weight, even if predominantly made up of extra muscle, is not neccessarily conducive to distance running.

Did you know that a pounds worth of gas is cheaper than a pounds worth of electricity?

Yes I agree but it's not the same with Kilos

My guess is you watch Ster Trek

So a kilo of fat doesn't weigh the same as a kilo of muscle???

He's yanking your chain Cinders
