The question is:

If I want to lose weight, how can I balance between calories deficit and building muscles!Ok, lifting weights is important because it increases the metabolism!
But, If i make a calories deficit to lose weight, how am I gonna build muscles!
Also, if I want to lose weight, should I keep increasing the weights that I left!! for example,,,I started three months ago with lifting 50 lb chest, now I can do 100 lb!! chest muscle got bigger but the fats are still in there and it looks ugly!!
Please,please and please, I really need a help about this!
Should I keep increasing the weights to lose weights and should I make a huge calories deficit or no?
Thanks a lot,
Forums is the only way that I can get a satisfying answer!!!
