To put it quite simply...because it's just not "FuN" most of the time.
We are creatures that are hardwired to not only look for the easiest solution to a problem but also one's that keep our interest level going.
Most of the time getting fit, staying on a diet or going on one just isn't a fun thing to do...nor is it a quick thing to do.
Henceforth, doctors coming up with surgeries to look "beautiful" instantly and pharmaceutical companies (and the like) coming up with pills to make you get "Skinny" despite the risk to one's health.
In short, if you make your diet or exercise program something that is fun or that you look forward to, you will have a higher success rate. :o)
