Men and the weight-gain obsession
I think it's fair to say that weight-loss is primarily a female obsession, but I see the reverse phenomenon, in young guys especially, in the quest to be bigger.
And the fitness industry is happy to enable the compulsion. Rippetoe is highly-respected in the industry, I'd go so far as to say revered. Of course he's popularized the GOMAD Diet. That's: Gallon Of Milk A Day.
Check out his before and after pics and you see him turning gangly adolescents into hulking (but now fat) adolescents.
Rippetoe, a bit chubby himself, is fairly glib about the transformation. After all, "you can always lose weight later."
But consider this: now the young male is doubly-bedeviled. Let's be honest, just as the young woman will never be thin enough, the young man will never be big enough. BUT NOW an additional compulsion has been cultivated: weight-loss anxiety WHERE IT DID NOT EXIST BEFORE.
