Something to explain the myth that "muscle weighs more than fat"....

But isn't this article saying that muscle does weigh more than fat therefore it isn't a myth. If a lb of fat takes up more space than a lb of muscle, then surely that means muscle weighs more for the same volume.

Nevertheless, this is a very useful article and shows that if we are exercising and sticking to plan we should never get upset by a slow down in weight loss or even a gain.

Teresa - I agree, for the same volume muscle does weigh more than fat, but 1lb of muscle is still the same weight as 1lb of fat, you'll just look smaller!

My point was more that we place so much reliance on the number on the scale (and so does SW) that if we hit a plateau it's really easy to get downhearted. I'd suggest that we take measurements so that we can see that we might be losing inches (and therefore changing the ratio of fat to muscle), rather than weight. After all, some Olympic athletes are classified as obese, yet they're pure muscle!
