Take the advice given above FBG & lets be very honest here your not lean YOU ARE very very skinny & 95% of women DO NOT like skinny blokes. You honestly need to put on quite a bit of weight.

Do not take this post as a dig take it as an honest view. You are way to skinny to even think about losing weight. In fact if you still consider you need to lose weight I'd be worried your developing a psychological eating disorder.

I'm with Ressie FBG - you need to put weight on! If you were my son, I'd have you eating a lot more!

To cut you need to have something to cut into
You can be lean/athletic with the use of supps just eat well and keep the diet clean with odd cheats. Lime Ressie said none of us hate you we just think you need to be more mature and start looking after yourself. Like big Si said if i had a lad your age i would suggest to him that he needed a healthy diet high in protein and train like a monster. It is possible to build muscle and stay lean you just have to be commited to hard work in the gym and outside of the gym.

If you want a lean(ish) athletic look, try to have a look at Ollie's pictures, Rab's pictures or maybe even my own pictures - those are all achievable physiques, with decent mass and leanness. Of course, guys like Orinoco and h4ni blow us mortals out of the water, but my point is, you can have pretty decent abs, while still being above 10% BF.
As many has said before me, you need to have something underneath to show off and bones just doesn't cut it.

Its already been said what to do about the training and diet.

When i was 16 i was 9 1/2 stone FBG. If i had the advice you are getting now it wouldnt have taken me as long to get to where I am now.

One thing i would say is that you shouldnt be afraid of cheating with meals. You could eat till you burst and you aint going to put on fat....you can tell by looking at the pic, you have the same bodytype as me.

I think you should be eating as much as you can and not pissing about worrying about counting calories and macros, or worrying about supplements too much, just eat lots.
