Men should certainly want to be in shape, but I can understand how some young boys especially might suffer from some poor self esteem because they don't look a certain way. From the article:
"Of the boys who were highly concerned with their weight, about half were worried only about gaining more muscle, and approximately a third were concerned with both thinness and muscularity simultaneously."
Even here on SoSuave, there is a heavy message that if you are not a ripped guy with huge muscles, a six pack, and low body fat, then you are a lazy AFC wimp that women are not going to find attractive. Notice the emphasis on being thin and muscular at the same time.
It's good in many ways that there is peer pressure that provides motivation to work out and be in shape. But for younger boys especially, some of them may have to wait a little while to grow into their bodies - until their bodies are actually mature enough to look like men. Meanwhile, posts like "What every skinny guy should know" are telling them that if they are skinny, then they are undesireable.
Since men are fast losing their natural role as breadwinner/hunter/gatherers and protectors, it seems like in the modern world the way they look is becoming more and more important. As such, the newer generations of males especially are probably falling prey to body image issues as much as women are. And men have no "fat is beautiful" interest group lobbying for them, lol.
