FG...I value your opinion so I'm hoping you can help me out with this a little bit. I'm always learning so I would like to get your thoughts on this.

Earlier you mentioned that it is possible to cut without doing cardio and without losing LBM. (This were when you were defending the statement made by another poster.)

I remember this Milos Sarcev video liked to this forum in the "so you wanta learn how to diet thread" (I think this was the name of it, it's been a while) He said a few things that seem to contradict some of what's been said in this thread. Now the last time I watched the video's was close to 3 years ago, so the info might be outdated. I forwarn you that this is very paraphrased and my memory might not be that good.

Anyway,

He was talking about how your body is always adapting. He gave an analogy about a woman who's BMR was at 2000cal/day who decided to drop weight and did a 500 cal deficit. He said after a while the body get's used to this deficit, and to counteract changes drops its' own BMR. So now the body saids 1500 calories is her BMR. After a while she stops losing the weight. So she drops another 500 calories from her diet. Her body says again it needs to reduce it's BMR. So now the BMR is 1000 calories a day....and so on, but you get the picture.

If this isn't outdate and in fact correct, it would seem to me that cardio is the only way to maintain LBM while still dropping fat. Based on diet alone without cardio or other cardio intensive activities in your daily life, it would seem that a calorie deficit will eventually lead to LBM loss because you can no longer get the nutrients your body needs to maintain its' muscle mass.

He went on to mention that this is why we do cardio. We still take in maintanence calories or a little below but do the cardio to counteract this and put us at a deficit. It makes sense to me, but maybe I have it all wrong. Can you explain this to me better?

Thanks
