Thank you for saying 1 lb of fat weighs the same as 1 lb of muscle. I have been so tired of hearing people say fat weighs more than muscle as if they've never heard of volume. I always say to compare how a pound of muscle looks to a pound of popcorn, then they get it. Thanks for the info and comparison.
Even before this, I had heard that cardio doesn't help with weight loss. Yet, at least among the many people whom I've personally known over many decades, _consistently_ the leanest are marathon runners, i.e. people who are engaged in one of the most excessive cardio exercises of our age. So, how is it that they don't have a lot of muscle (i.e. these are _lean_ runners, not body builders) nor do they have a lot of fat, and yet they consistently eat more than most people around them (including me)?
Did you measure their calories in? Eating a ton of healthy food is less Calories than a donut. And how do you know they don't have a lot of muscle? Normal people with a lot of muscle don't look big in clothes. Don't confuse that with instagram models on steroids. Also, the rule of "cardio doesn't burn more calories" breaks down once you get to ultra high volume professional athletes. But being an athlete has to be your job, 8 hours a day.
You are correct, marathon runners don't have a lot of excess fat storage and they don't necessarily have a low body fat percentage either. That last point is related to the fact that excessive cardio increases catabolic hormones (cortisol and adrenaline). These cause the breakdown of muscle tissue for energy and cortisol brings out fat-storing enzymes. Most certainly, marathon runners have developed a high blood volume pump per heartbeat, and increased their stroke volume and red blood cells - this gives them great endurance. They have also built up more slow twitch muscle fibres.But you will won't see a lot of toned (defined muscles) marathoners. Bodybuilders use fat as energy too, but cardio uses more (as long as the person is fit!)
Great explanation. Thank you
Thanks, do have a productive day!🎉
really good , keep going .........
Thanks so much

Yes, a pound is a pound is a pound....😅...
