Hairspray is a movie and not exactly reality.
I had an extremely bad stretch in my life (roughly 4 years) when my weight ballooned up from 80kg (177 lbs.) to 130kg (287 lbs.). I am 165cm. (5'-5").
I can confirm that I wasn't doing much dancing. The worst thing was living in a very beautiful city (Venice Italy) I could not even walk and enjoy the scenery, art, and whatever else was on offer. I couldn't move sufficiently to even exercise to lose the weight. At a certain point I started to find it incredibly difficult to wipe my own ass.
It took two full years and constant work to lose 50 kg.
I didn't even do that until I understood for certain that if I did not lose that weight it was a mathematical certainty that I would be dead. In the summer of 2003 I came within a whisker of dying from rampant infection as a consequence of, you guessed it, diabetes.
Mind you this all happened after more than 20 years of lifting weights in an extremely committed way (amongst other sports)
The messages there are a. if your in a sport your in it for life and b. if you take pharmacological supplements, even if prescribed by a doctor, you may be in for a rude surprise when you stop taking them, and you eventually must stop taking them!
I don't care much for the way obese people are treated in our society (especially considering that this is now 30% of the American population). My guess is fat prejudice just makes things worse. Neither do I buy the "fat is beautiful" or "fat liberation" arguments. They simply aren't true.
Money, no money, ripped, morbidly obese, and whatever else. The issue behind all of this is a matter of life and death health and not getting laid.
