I'm assuming that 'diet' refers to implementing a calorie restriction into their diet. In which case it obviously does work, but people not doing it is the issue.
I actually believe education in nutrition and specifically weight manipulation would help a lot. From my experience in talking with others, the average person's views on these topics is almost in the realm of magic due to being bombarded with false information from media and product companies.
With a solid understanding in these topics, one can implement changes into their diet and very easily assess why they are or aren't making progress towards their goals.
As it stands the average weight loss attempt with the understanding of weight loss as some form of black magic tends to result in temporary success or outright failure, with no way of being able to assess why or what to do about it. It is then usually concluded that one's 'genetics' are at fault.
