Some of the reasons that people want a quick fix:
- Media/social pressure to have that ‘perfect’ body
- look like your skinnier/leaner/more muscly friend
- instagratification: ‘fast results and get back to normal’
- minimum time and effort/maximum results
- the more extreme diet, the better it is
- lose a couple of kgs (lbs) a month is not as sexy as losing 15lbs in a month
