also:
does the weightlifting l do burn fat?
what l mean is
wlll lifting weights help me lose and burn fat?
im not intereseted in cutting weight, just burnign fat cause l know if l gain muscle l gain weight

Yes, but you wo not be able to see it. Cardio gives you that lean and cut look. Taking supplements would help your muscles grow, but in order to really burn off the fat, you need to do cardio. Even walking for 30 minutes a day, walking up the stairs to the 3rd floor instead of taking the elevator. Every little bit of cardio is still cardio.

Yes you can get muscular without cardio. Bodybuilders will go through a 'bulk' phase where they eat more and lift heavy to gain muscle then go through a 'cut' phase where they eat clean food and do cardio with weight training. You should definitely incorporate cardio into your routine because you are still overweight, get rid of the weight first add cardio to your routine. And taking whey protein alright anything else is not really necessary at your age.
