Bad news not only do diet pills not work, but so called dieters like you who try for the quick fix have a 2 in 3 chance of ending up heavier in the long term!

Do you see the box near the top of the page?
The one labelled ‘Search for questions: ‘?
Well type in ‘lose weight’.
You will find over 518,682 pre-existing questions.
Try the misspellings ‘loose weight’ and there are another 119,033
In all there are over 637,715 Health section questions requesting solutions to being or thinking you might be overweight.
On average these each yield 6 answers, that is nearly 4 million answers.
(Without searching for any other variations on the question!)

I can usefully summarise these answers in 4 words:

EAT LESS DO MORE. Are you desperate enough to try this???
