What are the healthiest foods for rapid detox and weight loss?

I would like to go on a cleanse and start a healthy regimen for the new year. What are the best foods/combinations to do a detox and then a weight loss regimen? Are these cleansers like Puristat a bunch of hog wash or are they any good? I know to keep a low carb, low sugar, low fat diet, but are there any super food secrets I should know? Or juicing recipes that are great? Thanks so much!
