The problem is the pendulum in fashion always swings to the extreme, from beefy super Rambo to waif thin, I don't think we'll ever see the extreme of portly and proud, as chubby chasers are generally off the mainstream and the health dangers inherent with being overweight.
If someone is starving himself(or herself) or resorting to drugs and diet aids to acheive the "new ideal' thin of the runway, then that is as unhealthy as sedentary and overweight. Naturally thin is as healthy as any normal physique, and most lanky males will bulk up after thirty-they usually don't get the middle age spread the larger physiques among us, myself included, must continually battle. The gaunt sunken eye-socket look is a bad message of body ideal to send out to anyone male or female. I don't think I need to mention how many lives have been cut short by eating disorders such as anorexia and bulemia and I hope that this doesn't result in a growing number of young males succumbing to disorders that have shattered so many women's lives.
In the face of an ever growing size and weight, waif thin may be an ideal that few will ever be able to acheive and idealizing this look can result in choices as unhealthy as those leading to a growing obesity problem. Yes, improved diets and nutrition has resulted in the average height and weight increasing in the last 45+ years, but the United States has seen a growing obesity problem in land of plenty in the areas of food and leisure.
There are numerous examples of attractive thin people and I doubt anyone can argue Audrey Hepburn wasn't a classic beauty in an era when curvier women were more accepted. By today's standards, Marilyn Monroe, Jane Russell, Mae West, and Susan Hayward would have been too overweight to be sex symbols or exude anything resembling glamor. They were fortunate to live in a time when a variety of body types were more accepted and today the media, not just fashion, seems to promote a more androgynous look. The message of men should be smooth and thin shouldn't be the universal ideal, as most men are thin and hairless, though hair can be shaven with little harm, at least that can be one's aesthetic ideal, but not another's and not cause irreversible damage or harm. |
