Trying Atkins a second time?

So I have done the Atkins before and lost a considerable amount of weight pretty fast. I would like to do the diet a second time but have heard that it doesn't work as well. I need to see results to stay on a diet. Is there a way to kick start the Atkins again or do any of you have ideas as to which diets have worked for you. Like I said I want to see the results otherwise I won't stick with it. Open to any and all suggestions and cleanses/pills that may work. Please don't write "a healthy balanced diet and exercise"..... I know that much.I lead a healthy lifestyle but need the extra boost.
