Diet supplement

Are you aware that 97% of diet supplement don't work? You have to look long and hard to find something really effective that is going to suit your body and lifestyle. You should get a lot of good advice before embarking on any course of treatment which includes supplements or medication of any sort. Don't forget that on 3% of what is available on the market is in any way effective, so there is a much better chance of being ripped off than there is of having good results.
How do they get away with it? Basically they exploit a weakness, they know that their clients won't make a fuss and will think it is their own fault if they don't lose weight, and they are happy to peddle useless pills and potions on a basis of empty promises.
