"muscle weighs more than fat"

[StealthPolarBear]

Sounds right, muscle is all dense and hard, fat is flabby, but is it correct? Can anyone quantify it?

Yes, it's correct. I can't remember the actual numbers, but it's something like 1lb of fat is 2.5x the size of 1lb of muscle.

muscle is denser not heavier.

1lb of fat weighs the same as 1lb of muscle, but the muscle takes up less room.

It annoys me when people say it weighs more! that's not possible

Hang on! A pound is a pound. If you're talking mass, which is different, then lean muscle takes up less space than fat.

Like this

1lb of muscle weighs the same as 1lb of fat

But I know what you mean, and you're right. Someone who is a size 10 but very muscly will probably weigh more than someone with the exact same measurements but who has a higher body fat percentage.

What sendcoffee said

What coffee said. It's the same as "starvation mode" - a dieting half-truth. I get so pissed off when somebody says they're not losing weight and people ask "yes, but are you eating enough?"

Sorry I did mean denser yes
Most people use the two interchangeably

Super I am with you on the starvation mode thing. Sounds like bad science to me

A pound of fat will weigh the same as a pound of muscle weight wise, the volume/mass will be different though

1 cubic centimetre of muscle will weigh more than 1 cubic centimetre of fat.

The age old argument. Just depends how you look at it. I see it as if you had a cup of each the muscle would be heavier yes.

Am I allowed to say I weigh more than a new born baby? Pound for pound we weigh the same :)

The argument stems from people obsessing about weight loss rather than fat loss. If you take 2 people who are both 12 stone, one has more lean tissue than the other who is going to look better?

Or lead weighs more than feathers

Can anyone quantify it

Starvation mode is not bad science
Eating too few calories drives cortisol up and disrupts the leptin-gherkin axis so means your body is 'stressed' into maintaining body stores

Hels you're the first person who has given a scientific sounding answer when I've asked. Still not convinced :) but thank you

Isn't ghrelin the hunger hormone, not gherkin...

Fat density: 0.9 grams per ml (g/ml).
Muscle density: 1.1 g/ml.

This means that muscle is around 20% denser than fat, and the same weight will take up around 20% less volume than fat.

I also recall reading somewhere that "starvation mode" only lasts around 3 days and therefore doesn't have a significant effect on weight loss. Can't cite a source though because I can't remember where I read it.

VLCD work-the problem is it's not a sustainable way to diet. You'll get hungry after the initial novelty wears off and potentially binge. They're too restrictive. I think that's where the starvation mode "myth" has come about. "Cheat meals" don't help matters either in some cases-if you eat 1400kcal a day then a 4000kcal "cheat meal" and your BMR is 1600kcal you need to burn another 2600kcal in additional exercise to offset the cheat.

Yes autocorrelation disaster
