First, calling someone you don`t know ignorant because he doesn`t agree with you is lame. Really lame. You shouldn`t do that. Especially because you clearly aren`t an expert in this field.
Now to the point. No, I never said that you don`t need fuel, I don`t know how you concluded that from my post, but whatever. You need fuel, but it`s an enormous difference between a 65 kg footballer and 90+ kg bodybuilder or recreational weightlifter. You need to eat well to gain/lose weight, but it`s nowhere near as dramatic as you describe it, especially when you are in a training regime most of your life. The problem is that an average sedentary person isn`t used to a strict regime of training and nutrition, so he finds it overwhelming at the beginning.
I`ve been training for the most of my life (big part of that with a pro coach), so I could say that I have pretty good first-hand experience of how a body works. Not that we are all the same, but general principles apply to everyone.
An athlete who doesn`t want to pack muscles just for show, but for enhancing athletic ability will never eat like a maniac and bulk up in 6-8 months or so. He will follow a strict regime for gaining lean muscle mass little by little at the same time with improving his maximum strength, muscular endurance etc.
