Lift hard and heavy, 8 meals a day. 1000 calories each(clean). grilled chicken, LEAN beef, fish. Oatmeal, potatos, broccoli, asparagus. Also, an orange with every other meal helps. I had the same issues when I first started to workout, I was a very hard gainer. 8000 calories seems like alot and you will probably hate food, but it works. @ 18 I was 6'0" and 170lbs, now 6'0" and 220 with about 15% bodyfat.
Reread his post, he wants to GAIN weight.
Yeah, I missed that. (It was, like, 3AM when I posted.)
OK, if you want to gain weight, you need to eat more and train properly.
I bought Jason Ferruggia's book, "Muscle Gaining Secrets", followed his training program and went from 72kg to 97kg within 8 months. (I'm 5'9", so to be 97kg/213lbs at that height is pretty solid!)

I can honestly recommend this book. I trained for 45 minutes a day, four days per week. That was all. The rest was simply a matter of getting the right nutrition.
I doubt your gains were from that fools book, his site reads like the very companies and magazines he's bashing.
Unreal! I wish I could eat 8K calories a day. I have trouble just getting in 4,500. And I hate food at even that low amount!!
Trust me, I hated it. Waking up to an alarm twice a night to force feed myself eggwhites and oatmeal.::9
