is jogging gonna make me lose muscle mass?

im 16 and 5 foot 10. i weigh 169 pounds. i am currently trying to get down too 160 pounds. my goal is coming quite nicely. as two months ago i weighed about 185. well in order to lose, i have cut my calories and have taken up running. i run between 3 to 5 miles per night. i have been reading things on the internet lately... and ive read some things that say that jogging makes you lose muscle? and cutting calories will make me lose muscle too? i really dont want to lose any muscle. the reason im trying to lose weight is so my muscles stick out more. if i lose the muscle with the weight, what did i really gain? can anyone help me with this? will jogging make me lose my muscle? will this be furthered by cutting cals? how can i continue to lose the fat but hold on too the muscle?

short answer, yes... when in a deficit you will lose muscle mass and fat. as long as you have a decent amount of mass, jogging and a deficit will make you appear more cut and you shouldnt notice yourself "wasting away"...just make sure not to go into too big of a deficit. my first cut i did and lost a lot of mass and strength.

Start sprint training instead bro, you will stimulate muscle growth and lose bodyfat:

While true, your source isn't credible at all. HIIT would be better, again not in a fasted state.

Last time I checked Erick Minor trains Olympic athletes and is a prestige strength coach, does he or his athletes look small or catabolic to you ? I don't think so ;)

No. You will not lose any muscle mass at all. Unless you are running marathons... There was a study about this.

This video explains it more in detail: /watch?v=hl0QiuoOHFk&feature=channel_video_title (Put youtube.com before /watch)

in terms of sprinting.. how much of sprinting will equal lets say an hour on the treadmill?

If you spend all your time running and not doing any weights, your body will use not only fat for energy, but also glycogen and amino acids. So yes, your muscles will also atrophy if all you do is run.

But a light-moderate amount of cardio, or high intensity training, can be useful in helping stimulate muscle gains.

thanks alot everyone. does anyone have any sugestions to continue losing fat but minimize muscle loss? any particular workouts?

dont have any suggestions on workouts, but i read that pork tenderloin is awesome for maintaining muscle mass. sorry i dont have the sources on this, i read it a couple weeks ago and cant find the articles or studies.

not lifting makes you lose muscle
