I do not care to be rude or on a high horse, but Charles is spewing completely false information. It is possible to gain muscle and lose weight. It is all about balancing your macros while being in a calorie deficit. Many studies show this. Though it is difficult to achieve, it is completely possible. There is a link to a summary of one such study below. Like I said before, it takes time.
Charles is somewhat correct when it comes to losing fat extremely quickly. If I were not on a cycle and using clen, t3, or some other cutting agent my muscles would become catabolic, or becoming lower in mass. A cycle would help preserve my muscle when trying to cut an extreme amount in an extremely short time.
Just trying to share some knowledge!
Good luck fellas.
